Google Claims Quantum Error Correction Advance

Google has claimed an advance in quantum computing related to the devilishly difficult problem of quantum error correction. In a blog post from Google and Alphabet CEO Sundar Pichai, he said company quantum AI researchers have “experimentally demonstrated” that by increasing the number of qubits – the basic unit of quantum information – it’s possible […]

Quantinuum Says It’s Near Quantum Error Correction Break-even Point

Quantinuum, which joins Cambridge Quantum software with Honeywell Quantum trapped-ion hardware, today announced it is close to a breakeven point in quantum error correction.

$25M Federal Funding for Quantum R&D for GlobalFoundries and PsiQuantum

Federal funding of $25 million has been awarded to semiconductor manufacturer GlobalFoundries and quantum development company PsiQuantum for quantum computing research and development. This funding, secured as a part of the recently passed Fiscal Year 2022 spending package, is intended to expand research conducted by the Air Force Research Laboratory in Rome, New York to […]

Quantum Start-up Alice&Bob Raises Є27M; Claims Error Correction Breakthrough

PARIS, 10 March, 2022: — French quantum computing startup Alice&Bob today announced what it said is an 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 […]

IonQ’s Barium Systems Demonstrate Qubit Readout Performance

COLLEGE PARK, MD – March 3, 2022 – Quantum computing company IonQ (NYSE: IONQ) today published results from its new barium-based quantum computer showing its state detection fidelity. The results reflect a 13x reduction in state preparation and measurement (SPAM) errors, a metric core to producing accurate and reliable quantum computers. On a per-qubit basis, […]

@HPCpodcast: The Recent Rush of Quantum News – Tech Advances, Partnerships, Investments

A recent rush of quantum news is the topic of the latest episode of @HPCpodcast, including the melding of quantum and desktop computing, quantum error correction (a problem that not long ago led to assertions that quantum “will never work”), quantum investment, M&A and partnerships, and the connection between quantum computing and HPC.

Riken Claims Quantum Breakthrough: Entanglement of Three Spin Qubits

Researchers at Japan’s RIKEN scientific research institute have claimed a breakthrough in quantum computing, increasing the number of silicon-based qubits that can be entangled to three from two, which they say improves the potential of spin qubits for realizing multi-qubit quantum algorithms and effectively addressing quantum error correction. Reporting recently in SciTechDaily, the five researchers […]

Quantum Errors Not Random, Tied to Cosmic Rays, Researchers Say

Research by a Lawrence Livermore National Laboratory (LLNL) physicist and a group of collaborators is shedding light on one of the major challenges to realizing the potential of quantum computing — error correction. In a new paper published in Nature and co-authored by LLNL physicist Jonathan DuBois, scientists examined quantum computing stability, particularly what causes errors and […]
