Quantum computers have been shown to solve some problems faster than ordinary computers, but so far all these problems have had little application. A quantum Monte Carlo algorithm could change that
IBM’s quantum computers aren’t useful – yet

A quantum version of a computer algorithm widely used in finance, engineering and scientific modelling shows promising signs of operating much faster than existing methods. Experts say there are many hurdles to overcome before it overtakes versions running on ordinary computers, but that the potential gains could be dramatic.
In recent years, several research groups have claimed to achieve “quantum advantage” – the point at which a quantum computer can complete a task that would be impossible for ordinary machines. But the benchmark problem typically …
