Quantum computing is at an interesting point. It’s at the cusp of being mature enough to solve real problems. But like in the early days of personal computers, there are lots of different companies trying different approaches to solving the fundamental physics problems that underly the technology, all while another set of startups is looking ahead and thinking about how to integrate these machines with classical computers — and how to write software for them. At Disrupt 2020 on September 14-18, we will have a panel with D-Wave CEO Alan Baratz, Quantum Machines co-founder and CEO Itamar Sivan and IonQ president and CEO Peter Chapman. The leaders of these three companies are all approaching quantum computing from different angles, yet all with the same goal of making this novel technology mainstream.

D-Wave may just be the best-known quantum computing company thanks to an early start and smart marketing in its early days. Alan Baratz took over as CEO earlier this year after a few years as chief product officer and executive VP of R&D at the company. Under Baratz, D-Wave has continued to build out its technology — and especially its D-Wave quantum cloud service. Leap 2, the latest version of its efforts, launched earlier this year. D-Wave’s technology is also very different from that of many other efforts thanks to its focus on quantum annealing. That drew a lot of skepticism in its early days but it’s now a proven technology and the company is now advancing both its hardware and software platform.

Like Baratz, IonQ’s Peter Chapman isn’t a founder either. Instead, he was the engineering director for Amazon Prime before joining IonQ in 2019. Under his leadership, the company raised a $55 million funding round in late 2019, which the company extended by another $7 million last month. He is also continuing IonQ’s bet on its trapped ion technology, which makes it relatively easy to create qubits and which, the company argues, allows it to focus its efforts on controlling them. This approach also has the advantage that IonQ’s machines are able to run at room temperature, while many of its competitors have to cool their machines to as close to zero Kelvin as possible, which is an engineering challenge in itself, especially as these companies aim to miniaturized their quantum processors.

Quantum Machines plays in a slightly different part of the ecosystem from D-Wave and IonQ. The company, which recently raised $17.5 million in a Series A round, is building a quantum orchestration platform that combines novel custom hardware for controlling quantum processors — because once quantum machines reach a bit more maturity, a standard PC won’t be fast enough to control them — with a matching software platform and its own QUA language for programming quantum algorithms. Quantum Machines is Itamar Sivan’s first startup, which he launched with his co-founders after getting his Ph.D. in condensed matter and material physics at the Weizman Institute of Science.

Our social media profiles are reflection of our true personalities. Needless to say, we make that extra effort to make them look and feel special. What helps us in the process is a powerful smartphone that can not only capture stunning photos and videos, but also help us quickly process and share them across to our friends and family members.

Samsung’s phones are known for their excellent smartphone cameras. Over the years, the company has been shipping highly innovative and impressive cameras on its flagship smartphones. Samsung is now bringing its innovative flagship camera experiences to its Galaxy A series phones, the Samsung Galaxy A51 and Galaxy A71. These new flagship-level features can help you spice up your social media profiles by capturing and sharing stunning photographs and videos.

Let’s take a look at some of the most impressive new camera features in Samsung’s Galaxy A71 and Galaxy A51 smartphones at can help you take your social media posts to the next level:

Single Take Makes Your Special Moments Extra Ordinary

Everything you do is worth sharing on your social media profiles and messaging platforms. Your social profiles help you stay connected to your loved ones by helping you share your most memorable moments. Single Take is a new feature on Galaxy A71 and Galaxy A51 smartphones, which was earlier available only on Samsung’s flagship Galaxy S20 series.

Single Take lets you indulge in your special moments, while still capturing the best parts of it. Imagine being at a birthday celebration of a loved one, and wondering about which camera mode to select. Single Take can help you enjoy the moment while still being able to capture all the important details in the form of 10 photos and videos based on the moment and lighting condition.

All you have to do is pick Single Take mode, and capture a moment for a few seconds. Your Galaxy A71 or Galaxy A51 phone will be able to deliver stunning photos and videos that ensure you don’t miss out on anything important, and still end up with a bunch of great photos and videos to share on your social media profile.

All you have to do is create a custom filter using any of your existing photos. Custom Filters uses on-device AI to capture the rich colours and vibes of your existing photos. You can then use these filters and apply them on new photos you capture on the Galaxy A71 or Galaxy A51 to create personalized photos. Once you share these on your social media profiles, they’ll look stunning and extraordinary, unlike anyone else’s photos.

Smart Selfie Angle to Make You and Your Friends Looks Great

Selfies are quite an essential part of social media. While everyone is shooting and sharing selfies, not all of them are going to look as good as yours, thanks to this highly innovative camera feature on the Galaxy A71 and Galaxy A51.

The new Smart Selfie Angle mode on the Samsung Galaxy A71 and Galaxy A51 help you capture great selfies with your friends. Every time you use the front camera to capture a selfie with your friends, the camera can automatically switch to a wide-angle mode. The mode is built to capture great details when more than one person is involved in a selfie. This means your selfies with your friends are going to look fabulous when you share them on your social media profiles.

AI Gallery Zoom Adds That Magical Touch to Existing Photos

AI Gallery Zoom is a great feature that can help you improve existing photos on your phone. For example, if you get one of your photos from a friend, on a messaging platform, it could turn out to be slightly blurred due to compression systems.

This feature ensures those unclear photos look more clear in your Gallery. It can make images look sharper and visually appealing, so you can easily share them on your social media profiles. The feature uses an on-device AI-powered mechanism so your personal data doesn’t leave your phone ever. The feature is also useful if you’re migrating from an older, less powerful smartphone, and are importing photos from it.

Switch Camera While Recording Is Perfect for Vlogging

While most smartphones feature front and rear cameras, they rarely let you capture a single video using both the cameras. Well, Samsung’s Galaxy A71 and Galaxy A51 phones can now let you record videos using both the cameras without stopping recording. It’s an amazing feature that’s perfect while you’re sharing live videos or simply making a quick vlog for your social media profiles.

Quick Videos Ensure You Don’t Miss Anything

Consider this, you come across a really special moment, and by the time you fire up the Camera app on your phone and start recording the video, it’s gone. Samsung Galaxy A71 and Galaxy A51 now come with a new feature called Quick Videos that takes care of this problem.

You can now quickly capture a video by long-pressing the shutter button. This way, you can easily record a great video and share it on your social media profile. Quick Videos feature is ideal while you’re at home or on a vacation, and you simply want to capture a quick moment and share it with everyone.

How to copy expressions without changing cell references in Excel

istock 1150345178

Microsoft Excel updates cell references when you copy an expression. Here are a couple of workarounds for those rare occasions when you don’t want to change the cell references.

Microsoft Excel has a helpful behavior in regard to copying expressions. After entering a row or column of expressions, you can copy them, and Excel will update the cell references according. Otherwise, you’d have to enter all expressions manually and that would be tedious and open to error. However, it’s not uncommon to run up against a situation when you won’t want to update the references. There’s no easy built-in way to do this. In this article, I’ll show you two quick workarounds for copying expressions without updating the cell references.

SEE: 60 Excel tips every user should master (TechRepublic)

I’m using Microsoft 365 on a Window 64-bit system, but this works in older versions. You can work with your own data or download the demonstration .xls file. Both methods work in the browser. 

How copy works with expressions in Excel

When you copy an expression by using the fill handle, Excel updates relative cell references. For instance, if you copy the simple expression =B3/C3 one cell to the right, Excel will adjust the column reference and enter the expression =C3/D3. If the column reference is absolute ($), Excel will change nothing, and copy =$B3/$C3. However, if you copy the expression down one row, Excel will update the row reference because it isn’t absolute: =$B4/$C4. The same behavior is in play whether you use Ctrl+C to copy the expression or move it. This behavior makes it difficult—impossible—to copy an expression when you don’t want to update the cell references unless all of those references are absolute: =$B$3/$C$3.

The easy way handles a single expression in Excel

If you have only a few expressions to copy, retaining the original references, you can use the formula bar in edit mode. It’s quick, easy and gets the job done. We can illustrate this using the simple data set shown in Figure A as follows:

  1. Select D3.
  2. Go to the formula bar and highlight the entire expression.
  3. Press Ctrl+C.
  4. Press Esc.
  5. Select the destination cell, F3, and press Ctrl+V.

As you can see in the data set to the right in Figure A, both expressions reference the same cells, B3 and C3. If you’re working in the browser, you’ll need to erase the ‘ character in the destination cell before it will evaluate the expression.

Figure A

  Let’s copy the expressions in column D without updating the cell references. 

This method is quick and easy but works with one or a few expressions. If you have a lot of expressions, this method will take a long time. Now, let’s look at a second method that takes a bit more work but works with lots of expressions simultaneously.

The hard way handles many expressions in Excel

If you want to make the same change to several instances of the same content, what tool do you usually use? Replace—that’s right! That’s the tool we’re going to use to copy many expressions without changing the cell references at the same time:

  • First, we’ll add a special character to the beginning of selected expressions using = as the Find string and # as the replace string Excel will treat the expressions as text 
  • Then, we’ll copy the expressions to the new destination.
  • Finally, we’ll replace the special character we used in step 1 with the = character.

SEE: How to expose expressions that return a defined error value in Microsoft Excel (TechRepublic)

Now, let’s run through a quick example using the expressions in column D:

  1. Select D3:D8.
  2. Press Ctrl+h or choose Replace from the Find & Select dropdown in the Editing group (on the Home tab)
  3. Enter = in the Find what control.
  4. Enter # in the Replace with control (Figure B). You don’t have to use #; you can use most any other character but use one that’s not in use or you might get unexpected results. That’s why I chose #. If # is in use, come up with another character or even a string of characters, such as AAA or ZZZ.
  5. Click Replace All.
  6. Click OK to confirm and Close.

As you can see in Figure C, Excel treats all of the selected expressions as text.

Figure B

excelcopyexp-b.jpg

  Enter the find and replace characters.

Figure C

excelcopyexp-c.jpg

  Excel displays the expressions as text.

Using your favorite copy and paste method, copy the contents of D3:D8 to F3:F8. Now, it’s time to replace the # character with the = character. To do so, repeat the above instructions, but in step 3, enter # and in step 4, enter =, reversing the original search strings. When you’re done, you will have matching expressions in columns D and F (Figure D). You can select both sets by creating a non-contiguous selection or you can run the Replace task twice.

Figure D

  With a few easy steps, you copied a selection of expressions without changing the cell references.

A Human-Computer Duet System for Music Performance

pret

Despite the popularity of virtual musicians, most of them cannot play together with human musicians following their tempo or create their own behaviors without the aid of human characters. The authors of a recent paper created a virtual violinist having these characteristics.

It can track music and adapt to the human pianist’s tempo varying with time and with performance, making the two voices harmonized. The virtual musician’s body movements are generated directly from the music. The motion generator is trained on a music video dataset of violin performance and a pose sequence synchronized with live performance is generated.

These features mean that the human musician can practice, rehearse, and perform music with the virtual musician like with a real human, by following the music content. The proposed system has successfully performed in a ticket-selling concert, where a movement from Beethoven’s Spring Sonata was played. 

Virtual musicians have become a remarkable phenomenon in the contemporary multimedia arts. However, most of the virtual musicians nowadays have not been endowed with abilities to create their own behaviors, or to perform music with human musicians. In this paper, we firstly create a virtual violinist, who can collaborate with a human pianist to perform chamber music automatically without any intervention. The system incorporates the techniques from various fields, including real-time music tracking, pose estimation, and body movement generation. In our system, the virtual musician’s behavior is generated based on the given music audio alone, and such a system results in a low-cost, efficient and scalable way to produce human and virtual musicians’ co-performance. The proposed system has been validated in public concerts. Objective quality assessment approaches and possible ways to systematically improve the system are also discussed.
