Priority Choice Experimental Two-qubit Tomography: Measuring One by One All Elements of Density Matrices
Karol Bartkiewicz, Antonín Černoch, Karel Lemr +1
In standard optical tomographic methods, the off-diagonal elements of a density matrix are measured indirectly. Thus, the reconstruction of , even if it is based on linear i…
Scheme for a linear-optical controlled-phase gate with programmable phase shift
Karel Lemr, Karol Bartkiewicz, Antonín Černoch
We present a linear-optical scheme for a controlled-phase gate with tunable phase shift programmed by a qubit state. In contrast to all previous tunable controlled-phase gates, the…
Temporal steering and security of quantum key distribution with mutually-unbiased bases against individual attacks
Karol Bartkiewicz, Antonín Černoch, Karel Lemr +2
Temporal steering, which is a temporal analogue of Einstein-Podolsky-Rosen steering, refers to temporal quantum correlations between the initial and final state of a quantum system…
