Control and enhancement of interferometric coupling between two photonic qubits
R. Stárek, M. Mičuda, I. Straka +4
We theoretically investigate and experimentally demonstrate a procedure for conditional control and enhancement of an interferometric coupling between two qubits encoded into state…
Experimental replication of single-qubit quantum phase gates
M. Mičuda, R. Stárek, I. Straka +4
We experimentally demonstrate the underlying physical mechanism of the recently proposed protocol for superreplication of quantum phase gates [W. Dür, P. Sekatski, and M. Skotiniot…
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…
Generation of tunable entanglement and violation of a Bell-like inequality between different degrees of freedom of a single photon
Adam Valles, Vincenzo D'Ambrosio, Martin Hendrych +4
We demonstrate a scheme to generate noncoherent and coherent correlations, i.e., a tunable degree of entanglement, between degrees of freedom of a single photon. Its nature is anal…
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…
