Quantum computers with millions of qubits are essential to solving some of humanity's toughest challenges. Integrating key qubit control electronics into the quantum chip architecture that holds the qubits is critical to achieving that scale.

Quantinuum, the world’s largest integrated quantum computing company, together with Microsoft, has achieved a breakthrough in making fault tolerant quantum computing a reality, by demonstrating the most reliable logical qubits with active syndrome extraction, an achievement previously believed to be years away from realization.

D-Wave Quantum announced that the 1,200+ qubit Advantage2 prototype is now available via the company’s Leap real-time quantum cloud service. Customers who have Leap service subscriptions can access the new Advantage2 prototype today, and those new to the Leap service can sign up and get up to one minute of free use of the actual quantum processing units (QPUs) and quantum hybrid solvers, including the new Advantage2 prototype.

Alice & Bob, a leading hardware developer in the race to fault tolerant quantum computers, in collaboration with the research institute Inria, today announced a new quantum error correction architecture – low-density parity-check (LDPC) codes on cat qubits – to reduce hardware requirements for useful quantum computers.

Atom Computing has been selected by the Defense Advanced Research Projects Agency (DARPA) to explore how Atom’s highly-scalable neutral atom technology will realize utility-scale quantum computing in the near term.

In a new paper in Nature, a team of researchers from JPMorganChase, Quantinuum, Argonne National Laboratory, Oak Ridge National Laboratory and The University of Texas at Austin describe a milestone in the field of quantum computing, with potential applications in cryptography, fairness and privacy.

Oxford Ionics, a world leader in trapped-ion quantum computing, today announced that it has been selected by the UK’s DSIT and Innovate UK for the Quantum Missions pilot to unlock scalable and commercially-useful quantum computing.

Researchers at the UChicago Pritzker School of Molecular Engineering (UChicago PME) have realized a new design for a superconducting quantum processor, aiming at a potential architecture for the large-scale, durable devices the quantum revolution demands.

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, today announced that it has completed the calibration and benchmarking of a 4,400+ qubit Advantage2 processor. This milestone marks a significant step forward in D-Wave’s ongoing development of its sixth-generation annealing quantum computing system. The latest Advantage2 processor shows substantial performance gains over the current AdvantageTM system in solving customers’ complex computational problems in areas such as optimization, AI, and materials science.

oday Microsoft announced a game-changing collaboration to extend our lead in the race: together we will build the world’s most powerful quantum computer on a path to scientific and commercial advantage. Microsoft and Atom Computing have been working closely together to accelerate the development of fault-tolerant quantum supercomputers that can solve impactful problems too difficult for even the most powerful classical supercomputing systems.
