Quantum Computing: IBM Just Created This New Way to Measure the Speed of Quantum Processors
IBM has run CLOPS to benchmark several of the company's quantum processors, ranging from five-qubit systems to 65-qubit devices.

To reflect exactly how fast a quantum computer can carry out a program, IBM is launching a new quantum speed metric, in a move that is likely to add a dose of competitiveness across an industry that is growing at pace.
Named CLOPS (Circuit Layer Operations Per Second), the metric is the first to measure the number of quantum circuits a quantum processing unit (QPU) can execute per unit of time, and is designed to provide an objective understanding of the amount of work a quantum system can do in a particular period.
Speed is only one of the three critical attributes that reflect the performance of a quantum computer, according to IBM, with the two others being scale and quality. Scale is measured by the number of qubits that the quantum processor supports, while quality can be determined thanks to quantum volume, which is another benchmark that IBM developed in 2017 to gauge how faithfully a quantum circuit can be implemented in a quantum computing system.
