People have performed many mathematical proofs to show that a quantum computer will vastly outperform traditional computers on a number of algorithms. But the quantum ...

In algorithms, as in life, negativity can be a drag. Consider the problem of finding the shortest path between two points on a graph — a network of nodes connected by links, or edges. Often, these ...

Here, we implement an iterative version of the order-finding algorithm 10,11 in which the control register contains only a single qubit, which is recycled n times using a sequence of measurement and ...
