Reporting in the February 26 issue of the journal Nature, a team of scientists from AWS and Caltech demonstrate a new quantum chip architecture for suppressing errors using a type of qubit known as a cat qubit. Cat qubits were first proposed in 2001, and, since then, researchers have developed and refined them. Now, the AWS team has put together the first scalable cat qubit chip that can be used to efficiently reduce quantum errors.

In a leap forward for quantum computing, a Microsoft team led by UC Santa Barbara physicists on Wednesday unveiled an eight-qubit topological quantum processor, the first of its kind. The chip, built as a proof-of-concept for the scientists’ design, opens the door to the development of the long-awaited topological quantum computer.

Quantum technologies hold the power to revolutionise industries such as cybersecurity, drug discovery and more. To help unlock the transformative potential of these technologies, the Dieter Schwarz Foundation and the National University of Singapore (NUS) are forging a strategic partnership to set the stage for a quantum-fuelled digital future.

D-Wave Quantum Inc. (“D-Wave” or the “Company”), a leader in quantum computing systems, software, and services, and the world’s first commercial supplier of quantum computers, and the Jülich Supercomputing Centre (JSC) at Forschungszentrum Jülich (FZJ) announced today that FZJ has purchased a D-Wave quantum computer, becoming the first high-performance computing (HPC) center in the world to own a D-Wave Advantage annealing quantum computing system.

Quantinuum, the world’s largest integrated quantum computing company, and RIKEN, Japan’s largest comprehensive research institution, today announced the successful on-premise installation of Quantinuum’s “Reimei” quantum computer at RIKEN’s Wako campus in Saitama, Japan. RIKEN has designed, prepared, and delivered a world-class facility for the trapped-ion quantum computer, which will enable generations of high-performance quantum systems.

Quandela, the European leader in photonic quantum computing, announces a major breakthrough for the sector in a scientific paper describing a reduction by a factor of 100,000 in the number of components required for fault-tolerant calculations. Quandela’s hybrid approach, based on a technology that generates photonic qubits with unprecedented efficiency from artificial atoms (semiconductor quantum emitters), should enable the company to accelerate the scaling-up of its quantum computers.

Physicists have built a new type of digital-analogue quantum simulator in Google’s laboratory, which can be used to study physical processes with unprecedented precision and flexibility. Two physicists from PSI’s Center for Scientific Computing, Theory and Data, played a key role in this achievement.

The formation of the universe after the Big Bang is the subject of ongoing research. A team of scientists from Jülich Supercomputing Centre at Forschungszentrum Jülich, the University of Leeds and the Institute of Science and Technology Austria has now succeeded in gaining important insights into false vacuum decay, a process related to the formation of the universe and the behaviour of particles on the smallest scales. The calculations were carried out with a quantum annealer that is connected to a classical supercomputer at the Jülich Supercomputing Centre. Using a combination of calculations on the supercomputer and the quantum annealer, scientists were able to understand the phenomenon of false vacuum decay. The results have been published in the journal Nature Physics.

Researchers at the University of Oxford have pioneered a new approach to simulate turbulent systems, based on probabilities. The findings have been published today in the journal Science Advances.

ParityQC and the University of Hamburg are joining forces for the ambitious new project QuADro, with the goal of applying quantum computing to the field of bioinformatics. The teams aim to develop novel algorithms and a development framework to use quantum computers for personalized drug development and drug repurposing.
