Demonstrations of Adaptive Quantum Measurements in Optics

Quantum measurement protocols make use of the quantum nature of the universe to gain more information about a system using fewer resources than would otherwise be possible. Achieving precision at the fundamental limits imposed by quantum mechanics nevertheless remains a challenge. Adaptive quantum measurement protocols may allow us to step closer to these ultimate limits. We present an overview of some interesting recent results of quantum measurement schemes as demonstrated in single-photon optical implementations, in the contexts of unambiguous phase estimation and multiple-copy non-orthogonal state discrimination.Quantum measurement protocols make use of the quantum nature of the universe to gain more information about a system using fewer resources than would otherwise be possible.
