Optimal entanglement-assisted discrimination of quantum measurements
M. Mikova, M. Sedlak, I. Straka +5
We investigate optimal discrimination between two projective single-qubit measurements in a scenario where the measurement can be performed only once. We consider general setting i…
Optimal single shot strategies for discrimination of quantum measurements
Michal Sedlak, Mario Ziman
We study discrimination of m quantum measurements in the scenario when the unknown measurement with n outcomes can be used only once. We show that ancilla-assisted discrimination p…
Process fidelity estimation of linear optical quantum CZ gate: A comparative study
M. Micuda, M. Sedlak, I. Straka +4
We present a systematic comparison of different methods of fidelity estimation of a linear optical quantum controlled-Z gate implemented by two-photon interference on a partially p…
Bounds on quantum process fidelity from minimum required number of quantum state fidelity measurements
Jaromir Fiurasek, Michal Sedlak
To certify that an experimentally implemented quantum transformation is a certain unitary operation U on a d-dimensional Hilbert space, it suffices to determine fidelities of outpu…
Distance to boundary and minimum-error discrimination
Erkka Haapasalo, Michal Sedlak, Mario Ziman
We introduce the concept of boundariness capturing the most efficient way of expressing a given element of a convex set as a probability mixture of its boundary elements. In other…
