Beam splitters as controlled-Z gate for hybrid state
Mikhail S. Podoshvedov, Sergey A. Podoshvedov
We explore a scheme based on adding a nonlocal photon and subtracting some number of photons to entangle the initial single-mode squeezed vacuum (SMSV) state with the photon state.…
Gain of squeezing via photon subtractions
Mikhail S. Podoshvedov, Sergey A. Podoshvedov, Sergei P. Kulik
We develop a method for generating a more squeezed than single-mode squeezed vacuum (SMSV) state by subtracting 2,4,6 photons from it. In general, the more photons are subtracted,…
Potential of photon-subtracted CV states towards gain sensitivity of the Mach-Zehnder interferometer
Mikhail S. Podoshvedov, Sergey A. Podoshvedov
Quantum Cramer-Rao (QCR) bound is attached to a particular nonclassical state, therefore appropriate choice of the probe state is of the key importance to enhance sensitivity beyon…
Quantum computing of analytical functions by linear optics methods
Mikhail S. Podoshvedov, Sergey A. Podoshvedov
We propose a model for computing of a certain set of analytical functions based on estimating the output distribution of multiphoton outcomes in an optical scheme with an initial s…
