Experimental implementation of optimal linear-optical controlled-unitary gates
Karel Lemr, Karol Bartkiewicz, Antonín Černoch +2
We show that it is possible to reduce the number of two-qubit gates needed for the construction of an arbitrary controlled-unitary transformation by up to two times using a tunable…
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…
Orthogonalization of partly unknown quantum states
M. Jezek, M. Micuda, I. Straka +3
A quantum analog of the fundamental classical NOT gate is a quantum gate that would transform any input qubit state onto an orthogonal state. Intriguingly, this universal NOT gate…
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…
