The concept of a quantum computer could provide answers to an algorithm without needing to run the program, which may sound “far-fetched”. However, recent findings indicate that they will far exceed the capabilities of the most advanced supercomputers available today.
In 1998, some scientists proposed the theory that quantum computers could sometimes find results without actually operating. This week, research experts at the University of Illinois (UIUC) announced they have successfully built such a computing system.
They transmitted light photons through a system of mirrors and other optical devices, using a simple program to search a database by altering the properties of the photons.
The new design is based on a trick known as the Zeno effect. This repetitive process prevents the photons from entering the actual program while allowing quantum interactions with the components of the program.
“The prospect of a computer that doesn’t run but still gives you the answer sounds odd but is very intriguing“, said Onur Hosten, a member of the development team. “Moreover, such a computer would produce fewer errors“.
