How Do You Measure Quantum Performance?

Introduction to Quantum Computing

Quantum Performance

According to Jay Gambetta, quantum computing performance can be determined by using three key metrics.  Those metrics are 1)scale, 2) quality, and 3) speed.  The scale is determined by the number of qubits.  The quality is assessed by using the quantum volume.  The speed is calculated by the 'circuit layer operations per second' (CLOPS) which measures how fast a quantum processor can execute circuits.  

Look at useful work that the quantum computer can do.  This requires having a large number of qubits which is important as indicates the problems that can be solved.  But this requires quality of the qubits.
