Optical quantum teleportation with known amplitude distorting factors of teleported qubits
Mikhail S. Podoshvedov, Sergey A. Podoshvedov
We develop a quantum teleportation protocol of an unknown optical single rail qubit using a hybrid quantum channel composed of continuous variable (CV) states of certain parity. Th…
Ultra-precise phase estimation without mode entanglement
Mikhail S. Podoshvedov, Sergey A. Podoshvedov
We explore optical quantum engineering of phase-parameterized continuous-variable (CV) probe states to exploit nonclassical light to solve the problem of precise phase estimation.…
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…
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…
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,…
