Comparing the relative quality of NISQ devices is difficult. Algorithms showing a quantum advantage are often tailored precisely to what a particular NISQ does well. We present a new algorithm for evaluating NISQs using quadratic nonresidues. We prove quantum computers can find quadratic nonresidues in deterministic polynomial time, whereas the classical version of this problem remains unsolved after hundreds of years. Using a restrictive computational rule set for finding quadratic nonresidues…

General theoretical foundations are laid for how to use special-purpose quantum computers with 40--50 high-quality qubits to demonstrate "quantum supremacy": that is, a clear quantum speedup for some task, motivated by the goal of overturning the Extended Church-Turing Thesis as confidently as possible.

In early 1994, it was demonstrated that a quantum mechanical computer could efficiently solve a well-known problem for which there was no known efficient algorithm using classical computers, i.e. testing whether or not a given integer, N, is prime, in a time which is a finite power of o (logN) .
