Quantum computers handle results even when not running

Scientists used a free-falling ball to explain the algorithm of quantum computers.

However, the recently published finding suggests that they will far exceed the capabilities of today's most modern supercomputers.

In 1998, some scientists theorized that quantum computers can sometimes find results without actually working. This week, researchers at the University of Illinois (UIUC) claim to have successfully built such a computer system.

They transmit light photons through a mirror system and other optical devices, along with a simple program, searching the database by changing the properties of the photon.

The new design was developed based on a trick called Zeno effect. The repetitive process will prevent photons from penetrating the actual program but allow quantum to interact with the elements of the program.

"The prospect of a computer is not running, but you still know the answer is odd but very interesting ," said Onur Hosten, a member of the development team. " Moreover, a computer like that will cause fewer errors ."
