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.…

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…

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…

Gain sensitivity of the Mach-Zehnder interferometer by photon subtraction strategy

Mikhail S. Podoshvedov, Sergey A. Podoshvedov

We study sensitivity of phase estimation of Mach-Zehnder (MZ) interferometer with original two-mode squeezed vacuum (TMSV) state. At the initial stage, the TMSV state is converted…

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…

Algorithm of quantum engineering of large-amplitude high-fidelity cat states in setup with k beam splitters and with inefficient photon number resolving detection

Mikhail S. Podoshvedov, Sergey A. Podoshvedov, Sergei P. Kulik

We present an algorithm of quantum engineering of large-amplitude>5 high-fidelity>0.99 even/odd Schrodinger cat states (SCSs) using a single mode squeezed vacuum (SMSV) state as re…

Family of CV states of definite parity and their metrological power

Mikhail S. Podoshvedov, Sergey A. Podoshvedov

We introduce a family of new continuous variable states of definite parity originating from even single mode squeezed vacuum state by subtracting an arbitrary number of photons fro…

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…
