I suppose all those with quantum programs ready to test, it's ready for you: I*BM’s new 53-qubit quantum ‘mainframe’ is live in the cloud* 20 Sep 2019 IBM has boosted its growing stable of quantum computers with a new 53-quantum bit (qubit) device, the most powerful ever offered for commercial use. Google announced a more powerful 72-qubit ‘Bristlecone’ model last year, but that was for its internal techies only. IBM’s, by contrast, feels significant because it can be used by absolutely anyone who can find a use for such a computer. The new and still-to-be-named computer will sit in the company’s Quantum Computation Center in Poughkeepsie, New York State, which has recently turned into a hotbed for commercial development. The facility also houses an array of older quantum computers, including one with 20 qubits (including the first Q System One launched in January), four with 5 qubits, and one with 14 qubits. The involvement of Poughkeepsie is no coincidence – this is the heritage site where IBM built many of the mainframes that made its name synonymous with business computing. Might quantum computers be on course to be the mainframes of the 21st century? https://nakedsecurity.sophos.com/2019/09/20/ibms-new-53-qubit-quantum-mainframe-is-live-in-the-cloud/ @philipthrift -- You received this message because you are subscribed to the Google Groups "Everything List" group.
