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.

How to copy expressions without changing cell references in Excel
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.
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.
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:
Go to the formula bar and highlight the entire expression.
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.
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.
Now, let’s run through a quick example using the expressions in column D:
Press Ctrl+h or choose Replace from the Find & Select dropdown in the Editing group (on the Home tab)
Enter = in the Find what control.
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.
Click Replace All.
Click OK to confirm and Close.
As you can see in Figure C, Excel treats all of the selected 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.

A Human-Computer Duet System for Music Performance
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.
