Quantum computers could run artificially intelligent algorithms that initially appear to require too much computational power thanks to a new method for writing quantum programs.

While quantum computers have the potential to outperform conventional computers for many different types of calculations, so far they have only done so for a few specialised computations. That is because those that currently exist are relatively small and not very powerful.

S. C. Marshall at Leiden University in the Netherlands and his colleagues wanted to…
