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…
Receipt of hybrid entangled and CV entangled states on demand
Sergey A. Podoshvedov, Mikhail S. Podoshvedov
We propose a new approach to the generation of entangled states, both hybrid and consisting exclusively of continuous variable (CV) states. A single mode squeezed vacuum is mixed w…
Universal DV-CV interaction mechanism for deterministic generation of entangled hybridity
Mihail S. Podoshvedov, Sergey A. Podoshvedov
We propose a general approach for the implementation of the hybrid entangled states consisting of continuous variable (CV) and discrete variable (DV) states. Peculiarities of DV-CV…
