Experimental realization of linear-optical partial SWAP gates
A. Cernoch, J. Soubusta, L. Bartuskova +2
We present a linear-optical implementation of a class of two-qubit partial SWAP gates for polarization states of photons. Different gate operations, including the SWAP and entangli…
Programmable discriminator of coherent states - experimental realization
L. Bartuskova, A. Cernoch, J. Soubusta +1
The optical implementation of the recently proposed unambiguous identification of coherent states is presented. Our system works as a programmable discriminator between two, in gen…
Several experimental realizations of symmetric phase-covariant quantum cloner of single-photon qubits
J. Soubusta, L. Bartuskova, A. Cernoch +2
We compare several optical implementations of phase-covariant cloning machines. The experiments are based on copying of the polarization state of a single photon in bulk optics by…
