NP-Complete problems are a class of complexity problems that currently have no time-efficient algorithm. In gene analysis, genes are clustered by their similar reactions to certain Quantum + NP-Complete = No problem. We haven't been able to solve NP-Complete problems since the 1950s Informally, a problem is NP-complete if answers can be verified quickly, and a quick algorithm to solve this problem can be used to solve all other NP problems quickly. Note: A trivial example of NP, but (presumably) not NP-complete is finding the bitwise AND of two strings of N boolean bits
