Quantum walks have emerged as an interesting candidate for the implementation of quantum information processing protocols. Optical implementations of quantum walks have been demonstrated by various g...
Demonstration of Deutsch's Algorithm on a Stable Linear-Optical Quantum Computer
Demonstration of Deutsch's Algorithm Stable Linear-Optical Quantum Computer
2010/10/20
We report an experimental demonstration of quantum Deutsch’s algorithm by using linear-optical
system. By employing photon’s polarization and spatial modes, we implement all balanced and constant fun...
