How much faster will quantum computers be?
In 200 seconds, the machine performed a mathematically designed calculation so complex that it would take the world’s most powerful supercomputer, IBM’s Summit, 10,000 years to do it. This makes Google’s quantum computer about 158 million times faster than the world’s fastest supercomputer.
How is the quantum volume of a processor calculated?
Roughly, the quantum volume is a measure of the effective number of qubits a processor has. It is calculated by determining the largest number of qubits on which it can reliably run circuits of a prescribed type. You can think of it loosely as a quantum analogue of the LINPACK benchmark.
What kind of problem is quantum volume used for?
The problem used for computing quantum volume is called the heavy output generation problem. It has roots in the proposals for demonstrating quantum advantage [5].
What is the heavy output probability of a quantum computer?
Heavy output probability = 0.792 Each circuit in a circuit family has its own heavy output probability. If our quantum computer is of high quality, then we should expect to see heavy outputs quite often across all the circuits.
How is the success of a quantum computer determined?
Different quantum computers are tasked with solving the same problem, and the success will be a function of many properties: error rates, qubit connectivity, even the quality of the software stack. A single number won’t tell us everything about a quantum computer, but it does establish a framework for comparing them.
