@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 […]
