Chart Showing the Possible Evolution of Quantum Threats. Source: GQI's State of Play Presentation There was a recent flurry of concern over the strength of the Lattice based encryption algorithms approved by NIST due to a paper titled Quantum Algorithms for Lattice Problems published earlier this month by Yilei Chen, a professor at the Tsinghua University Institute for Interdisciplinary Information Science (IIIS). Two algorithms this would possibly have affected include ML-KEM (CRYSTALS-Kyber) and ML-DSA (CRYSTALS-Dilithium) which use an LWE (Learning with Errors) approach. These algorithms are based upon the computationally hard problems of determining the length of the shortest nonzero vector [...]

Credit: Horizon Quantum Computing It's no secret that the best way to achieve maximum performance from a quantum system is to establish a very tight integration between the hardware and software stacks. This allows the software to take advantage of all the idiosyncrasies in the hardware to obtain every ounce of performance that it can. And achieving this maximum performance is surely needed as the industry races to achieve systems that can provide [...]

Progression of Quantuum's Improvements in Quantum Volume Performance. Credit: Quantinuum Quantinuum has always had a strategy of providing users with qubits that demonstrated the highest possible measure of qubit quality, as measured by both gate fidelity metrics as well as the Quantum Volume measure originally proposed by IBM. In fact, in 2020, they declared a goal of continuing to improve the Quantum Volume measure of their machines by a factor of 10X each year. And to their credit, they have continued to meet or beat this goal every year. Now, they have reached a new level of qubit quality performance on [...]

How to Celebrate a Hundred Years of Quantum Mechanics Bard Professor Paul Cadden-Zimansky wants everyone from kindergarteners to CEOs to celebrate the International Year of Quantum Science and Technology in 2025. One of his goals for the initiative is to illustrate the many pathways to jobs in science and technology. He shares his own story that includes both a C in high school physics and a successful career as a professor and superconductivity researcher. Paul Cadden-Zimansky is an associate professor of physics and director of the Physics Program at Bard College. A condensed matter physicist, Paul earned his Ph.D. from Northwestern [...]

Quantonation Ventures revealed the initial closing of its second early-stage investment fund, Quantonation II, with €70 million ($75M USD) raised towards a €200 million ($214M USD) goal. Focused on Quantum Technologies, the fund underscores Quantonation's leading role in the burgeoning Quantum Tech industry, with investments already being made globally. Since its inception in 2018, Quantonation has backed founders translating quantum science and physics into real-world applications across sensing, communication, and computing.  Its first fund, Quantonation I, exceeded its target by securing €91 million ($97M USD), investing in 27 companies globally, and achieving two exits. This success places Quantonation in the top [...]

IBM Quantum System One Installation at RPI's Voorhees Computing Center. Credit: IBM We had reported last June that Rensselaer Polytechnic Institute (RPI) had ordered an 127-qubit IBM Quantum 'Eagle' processor for on-premise use. Now IBM and RPI have announced that they've completed installation at RPI's Voorhees Computing Center, a facility which used to be a former cathedral. This is the first installation that IBM has performed at a university. IBM had previously installed a Quantum System One at the Cleveland Clinic last year. RPI will be using the machine to perform quantum computing research as well as train future quantum computing professionals. [...]

Infleqtion has named Matthew Kinsella as their new Chief Executive Officer replacing Scott Faris who has decided to leave the company to focus on quantum industry policy and investments in national security and defense. Mr. Kinsella was previously a senior Managing Director at Maverick Ventures and was one of the earliest investors in Infleqtion, when it was originally named ColdQuanta. He has served on the company's board since 2018 and knows the company well. He will be focusing on continuing to  scale Infleqtion's business and expand their sales into high-growth markets. A press release from Infleqtion announcing his appointment is available [...]

Chart Showing Improvement in Error Rates with this Latest Research. Credit: Quantinuum The race to achieve fault tolerant quantum computing (FTQC) will need many steps in order to cross the goal line and provide a usable capability so that end users can take advantage of it for their applications. But Quantinuum and Microsoft have moved the ball further downfield with their latest experiment. OverviewBasic quantum error correction groups together a bunch of error prone physical qubits with a coding scheme to form a logical qubit that shows a greatly decreased error rate. More advanced schemes increase the rate of encoding. A key [...]
