Linear-Optical Implementation of Perfect Discrimination between Single-bit Unitary Operations
arXiv:0801.3493 · doi:10.1088/0953-4075/41/19/195501
Abstract
Discrimination of unitary operations is a fundamental quantum information processing task. Assisted with linear optical elements, we experimentally demonstrate perfect discrimination between single-bit unitary operations using two methods--sequential scheme and parallel scheme. The complexity and resource consumed in these two schemes are analyzed and compared.
