Improving the efficiency of quantum engineering of SCSs by adding two demultiplexed input photons
Mikhail S. Podoshvedov, Sergey A. Podoshvedov
Conditional addition and subtraction of photons is a powerful tool for quantum engineering of continuous variable (CV) states that forms the fundamental building blocks of advanced…
Transfer of entanglement from nonlocal photon to non-Gaussian CV states
Mikhail S. Podoshvedov, Sergey A. Podoshvedov
Continuous variable (CV) entanglement refers to the type of entanglement of quantum wave-like systems that are described by continuous variables in an inherently infinite-dimension…
Schr{ö}dinger cat state formation in small bosonic Josephson junctions at finite temperatures and dissipation
D V Tsarev, D V Ansimov, S A Podoshvedov +1
In this work, we consider the feasibility of Schr{ö}dinger cat (SC) and states formation by a convenient bosonic Josephson junction (BJJ) system in two-mode approximation. S…
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…
