French quantum computing startup, Alice&Bob, announced a major advance towards the first marketable quantum computer. In a major scientific breakthrough, Alice&Bob has eliminated one of the main barriers to, and significantly reduced the complexity of, delivering a functional quantum computer – a goal that could now be within reach.
Alice et Bob demonstrate that their cat-qubit stabilization scheme is compatible with macroscopic bit-flip times: they increased the resilience to bit-flip errors from a previous record of a few milliseconds to 2 minutes…
A Sydney-based start-up, Q-CTRL, has released the results of its algorithmic benchmarking experiments, which demonstrate massively improved performance of quantum computers when an error suppression technique is applied. The technique achieved an improvement of over 2,500 per cent.
Amazon Web Services (AWS) Center for Quantum Computing opens new facility at the California Institute of Technology with the aim of building a bigger, more accurate quantum computer.
Researchers from The University of Maryland and IonQ, Inc. (“IonQ”) (NYSE: IONQ), a leader in trapped-ion quantum computing, on Monday published results in the journal Nature that show a significant breakthrough in error correction technology for quantum computers. In collaboration with scientists from Duke University and the Georgia Institute of Technology, this work demonstrates for the first time how quantum computers can overcome quantum computing errors, a key technical obstacle to large-scale use cases like financial market prediction or drug discovery.

Quantum computers are advancing at a rapid pace and are already starting to push the limits of the world’s largest supercomputers. Yet, these devices are extremely sensitive to external influences and thus prone to errors which can change the result of the computation. This is particularly challenging for quantum computations that are beyond the reach of our trusted classical computers, where we can no longer independently verify the results through simulation. “In order to take full advantage of future quantum computers for critical calculations we need a way to ensure the output is correct, even if we cannot perform the calculation in question by other means,” says Chiara Greganti from the University of Vienna.
Work by Los Alamos and others shows that hybrid quantum-classical algorithms can accommodate limited qubits and lack of error correction for real-world tasks.
