Optimal quantum state identification with qudit-encoded unknown states
Ulrike Herzog
We consider the problem of optimally identifying the state of a probe qudit, prepared with given prior probability in a pure state belonging to a finite set of possible states whic…
A folded-sandwich polarization-entangled two-color photon pair source with large tuning capability for applications in hybrid quantum architectures
Otto Dietz, Chris Müller, Thomas Kreißl +4
We demonstrate a two-color entangled pho ton pair source which can be adapted easily to a wide range of wavelengths combinations. A Fresnel rhomb as a geometrical quarter-wave plat…
Optimal measurements for the discrimination of quantum states with a fixed rate of inconclusive results
Ulrike Herzog
We study the discrimination of N mixed quantum states in an optimal measurement that maximizes the probability of correct results while the probability of inconclusive results is f…
Optimal state discrimination with a fixed rate of inconclusive results: Analytical solutions and relation to state discrimination with a fixed error rate
Ulrike Herzog
We study an optimum measurement for quantum state discrimination, which maximizes the probability of correct results when the probability of inconclusive results is fixed at a give…
Optimized maximum-confidence discrimination of N mixed quantum states and application to symmetric states
Ulrike Herzog
We study an optimized measurement which discriminates N mixed quantum states occurring with given prior robabilities. The measurement yields the maximum achievable confidence for e…
Experimental Optimum Maximum-Confidence Discrimination and Optimum Unambiguous Discrimination of Two Mixed Single-Photon States
Gesine A. Steudle, Sebastian Knauer, Ulrike Herzog +4
We present an experimental implementation of optimum measurements for quantum state discrimination. Optimum maximum-confidence discrimination and optimum unambiguous discrimination…
