Bristol University demonstrates world's-first optical quantum computer

Abstract:
The University of Bristol has created the world's first optical quantum computer capable of performing mathematical calculations. The computer used single particles of light (photons) passing through a silicon chip to work out the prime factors of the number 15 (three and five). The chip has four photons that carry the input for the calculations (in binary a four-digit input allows for all numbers between 0 and 15). The input is analysed using a quantum program, which calculates the prime factors.

"The really exciting thing about this result is that it will enable the development of large scale quantum circuits for photons. This opens up all kinds of possibilities," said O'Brien.
