On quantum operations of photon subtraction and photon addition
S. N. Filippov
The conventional photon subtraction and photon addition transformations, and , are not valid quantum oper…
Effect of incoherent pump on two-mode entanglement in optical parametric generation
S. V. Vintskevich, D. A. Grigoriev, S. N. Filippov
Pumping a nonlinear crystal by an intense radiation results in the optical parametric generation of photons in two modes (the signal and the idler). The quantized electromagnetic f…
Divisibility of quantum dynamical maps and collision models
S. N. Filippov, J. Piilo, S. Maniscalco +1
Divisibility of dynamical maps is visualized by trajectories in the parameter space and analyzed within the framework of collision models. We introduce ultimate completely positive…
Single photon-added coherent states: estimation of parameters and fidelity of the optical homodyne detection
S. N. Filippov, V. I. Man'ko, A. S. Coelho +2
Travelling modes of single-photon-added coherent states (SPACS) are characterized via optical homodyne tomography. Given a set of experimentally measured quadrature distributions,…
