We propose and explore the families of fully tunable, conditional 2 x 2 frequency-domain beamsplitters that result from sideband coupling in phase modulators. Full tunability is obtained by tailoring the driving voltage ...

[EN] This paper provides a review of the most important and widely used Quantum Key Distribution systems and then describes our recently proposed scheme based on Subcarrier Multiplexing that opens the possibility of parallel ...
[EN] Many components that are employed in quantum information and communication systems are well known photonic devices encountered in standard optical ¿ber communication
systems, such as optical beamsplitters, waveguide ...

In a recent paper, [4] have developed a scheme for the stochastic implementation
of arbitrary quantum operations on multimode single-photon qudit states by using
reconfigurable linear-optic systems. Based on this idea, ...
