rQOPS
{{Short description|Metric for a quantum computer's capabilities}}
{{Lowercase title}}Reliable Quantum Operations Per Second (rQOPS) is a metric that measures the capabilities and error rates of a quantum computer. It combines several key factors to measure how many reliable operations a computer can execute in a single second: logical error rates, clock speed, and number of reliable qubits.{{r|Dive}}{{r|Copilot}}{{r|Practical}}
The quantities included in rQOPS can be measured in all quantum computer architectures, allowing different architectures to be compared with one standard metric. A larger rQOPS measurement indicates a faster and more accurate device capable of solving more complex problems.
Microsoft suggest that a machine with 1 million rQOPS qualifies as a quantum supercomputer.{{r|Practical}}{{r|Dive}}{{r|Omdia}}
Alternative benchmarks include quantum volume, cross-entropy benchmarking, Circuit Layer Operations Per Second (CLOPS) proposed by IBM and IonQ's Algorithmic Qubits.{{r|Forbes}}{{r|IBM}}{{r|IonQ}} However, as opposed to considering qubit performance alone, rQOPS measures how capable a quantum system is at solving tangible problems.
Definition
rQOPS is calculated as rQOPS=Q x f, at a corresponding logical error rate pL., where Q is the number of logical qubits and f is the hardware's logical clock speed. Microsoft has selected this metric for the higher quantum computing implementation levels as it encompasses scale, speed, and reliability.{{r|Dive}}
