Figure Comparing Bit Flips, Phase Flips, and Erasure Errors. Credit: AWS There are a lot of different quantum error corrections being researched right now and Amazon has just published a paper on Physical Review X that shows an additional one they are researching. This actually came a little bit as a surprise to us because they had previously published papers on some completely different error correction algorithms including one on Schrödinger-cat qubits and another on concatenating the surface code with Gottesman, Kitaev, and Preskill (GKP) qubits. As explained to us by Dr. Oskar Painter, Head of Quantum Hardware at Amazon Web [...]

Vescent Photonics has named Russ Fein as its Chief Financial Officer (CFO) and Board Member. As a Managing Director of investment bank Corporate Fuel Partners, Russ played a key role in arranging Vescent's recent $5 million seed financing. Corporate Fuel takes an active role in their investments and Russ will be working with Vescent as part of this strategy. He has over 30 years of experience in a variety of financial firms as well as serving as a Board Member and has experience with a wide variety of technical based industries including biopharma, laser micromachining, software, and others.

Today’s quantum platforms need to radically scale-up to deliver on quantum computing’s true commercial promise. Innovation to meet this challenge continues to throw focus onto new parts of the quantum stack. Quantum networking technology is closely connected to modularity and so much more central to this quest than is commonly realized. Forward thinking quantum players, ecosystem builders and investors are already charting their strategies to maximize their share of this prize. The best of today’s early quantum systems are already capable of notional ‘beyond classical’ calculations. This starts to be possible with a high fidelity 50-60 qubit module where environmental noise [...]

One thing to understand is that quantum computing may not be the only game in town when one is looking for faster alternatives to classical computers. Recently, two companies have made introductions within the past week of physics based computational devices targeted at specific applications they they contend will be even more effect at solving problems than either classical or quantum computing. The first is a company based in Israel called LightSolver that has just introduced its LPU100 system that uses 100 lasers to solve tough optimization problems. They are now providing early access to a cloud based system accessible via [...]

By Amina Bashir and Doug Finke One of the key applications of quantum technology is to create a quantum network that can communicate messages and quantum states in a way that gives them more protection and other properties due to the laws of physics. Although this research is still very early, a number of organizations have started to create quantum testbeds to try out these quantum networks in order to continue developing them and advancing the technology. Most of these testbeds are used for Quantum Key Distribution, which one might argue as the simplest application for a quantum network. However, later [...]

NVIDIA is making a slew of product and other AI-related announcements this week during its annual GTC conference. But not to be overlooked are several announcements related to their quantum computing efforts which cover new supercomputer projects, academic initiatives, quantum clouds, and PQC acceleration. We will describe all of these announcements in this article. First, the company announced projects at two supercomputing centers to create large quantum emulation capabilities using their H100 Hopper architecture GPU and CUDA-Q programming platform. The first, called ABCI-Q, will be built by Fujitsu and located at the G-QuAT ABCI Supercomputing Center at Japan's National Institute of [...]

Credit: Journal of Physical Chemistry Chemical Physics If you had asked us six months ago, when we thought fault tolerant quantum computers would become available, we would have estimated some time around the 2030 timeframe. We would have indicated that between now and 2030, available quantum computers would all be NISQ based and that a few users would be able to figure out how to use these NISQ machines to achieve quantum advantage for a few applications during this period. But over the past few months, we have seen a large number of technical papers and roadmaps that indicate what we [...]

Rigetti Computing has announced its Q4 2023 and 2023 financial results. A quick summary of some key financial metrics comparing the Q4 2023 versus Q3 and 2022 is shown in the chart below. Other significant financial information disclosed during the company's conference call included that they raised $5.5 million in cash in Q4 from a stock sale agreement with B. Riley and an additional $12.8 million in cash after the Q4 2023 quarter closed from the same agreement. The company filed a shelf registration statement with the SEC in December to potentially raise up to $250 million. At their current projections, [...]

Brian Lenahan founded the Quantum Strategy Institute to demystify quantum technology for the global business community. As a Quantum Top Voice on Linked In, he does this via informative and interesting posts and through his three-times-a week newsletter, “Quantum’s Business.” In this interview, he explains why every organization needs a quantum strategist and why evaluating quantum solutions doesn’t require a physics degree. Transcript Veronica Combs: So if you are new to quantum technology and you really want to get an understanding of this industry and everything going on, one person you absolutely should know is Brian Lenahan. Brian is the founder [...]

Qrypt, a quantum-secure encryption company, has announced the launch of its Quantum Entropy and Quantum Secure Key Generation technologies. These technologies will be used to transmit AI workloads using NVIDIA BlueField-3 DPUs with quantum-secure encryption, providing protection against quantum computing threats to current cryptography. Most recently, Qrypt announced a Phase 1 contract with the Air Force to enhance national defense capabilities against quantum threats.  The announcement of the partnership between NVIDIA and Qrypt is a logical next step in this ambition, as Qrypt provides highly secure entropy, specifically in this context: Qrypt offers quantum-secure encryption for AI workloads using NVIDIA BlueField-3 [...]
