BOSTON, March 4, 2019 /PRNewswire/ -- At the 2019 American Physical Society March Meeting, IBM (NYSE: IBM) unveiled a new scientific milestone, announcing its highest quantum volume to date. Quantum Volume is a measurement, a procedure developed by IBM, that determines how powerful a quantum computer is, accounting for both gate and measurement errors, device cross talk, as well as device connectivity and circuit compiler efficiency. It follows that the higher the Quantum Volume, the more real-world, complex problems quantum computers can potentially solve, such as simulating chemistry, modeling financial risk, and supply chain optimization.

IBM has doubled the power of its quantum computers annually since 2017. IBM first made quantum computers available to the public in May, 2016 through its IBM Q Experience quantum cloud service.

IBM's recently unveiled IBM Q System One quantum computer, with a fourth-generation 20-qubit processor, has produced a Quantum Volume of 16, roughly double that of the current IBM Q 20-qubit IBM Q Network devices, which have a Quantum Volume of 8.

"Today, we are proposing a roadmap for quantum computing, as our IBM Q team is committed to reaching a point where quantum computation will provide a real impact on science and business," said Dr. Sarah Sheldon, lead of the IBM Q Quantum Performance team, dedicated to quantum verification at IBM Research. "While we are making scientific breakthroughs and pursuing early uses cases for quantum computing, our goal is to continue to drive higher quantum volume to ultimately demonstrate quantum advantage."
