IBM Doubles Quantum Volume with 28 Qubit Raleigh System

All qubits are not created equal. Over at the IBM Blog, Jerry Chow and Jay Gambetta write that the company’s new Raleigh 28-qubit quantum computer has achieved the company’s goal of doubling its Quantum Volume. The development marks a shift from experimentation towards building Quantum Computers with a systems approach.

“At the 2019 American Physical Society March Meeting, 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.”
