Matrix product channel: Variationally optimized quantum tensor network to mitigate noise and reduce errors for the variational quantum eigensolver
Sergey Filippov, Boris Sokolov, Matteo A. C. Rossi +5
Quantum processing units boost entanglement at the level of hardware and enable physical simulations of highly correlated electron states in molecules and intermolecular chemical b…
On quantum operations of photon subtraction and photon addition
S. N. Filippov
The conventional photon subtraction and photon addition transformations, and , are not valid quantum oper…
Effect of incoherent pump on two-mode entanglement in optical parametric generation
S. V. Vintskevich, D. A. Grigoriev, S. N. Filippov
Pumping a nonlinear crystal by an intense radiation results in the optical parametric generation of photons in two modes (the signal and the idler). The quantized electromagnetic f…
Divisibility of quantum dynamical maps and collision models
S. N. Filippov, J. Piilo, S. Maniscalco +1
Divisibility of dynamical maps is visualized by trajectories in the parameter space and analyzed within the framework of collision models. We introduce ultimate completely positive…
Dissociation and annihilation of multipartite entanglement structure in dissipative quantum dynamics
Sergey N. Filippov, Alexey A. Melnikov, Mario Ziman
We study the dynamics of the entanglement structure of a multipartite system experiencing a dissipative evolution. We characterize the processes leading to a particular form of out…
Single photon-added coherent states: estimation of parameters and fidelity of the optical homodyne detection
S. N. Filippov, V. I. Man'ko, A. S. Coelho +2
Travelling modes of single-photon-added coherent states (SPACS) are characterized via optical homodyne tomography. Given a set of experimentally measured quadrature distributions,…
Quantum computing based on space states without charge transfer
S. Filippov, V. Vyurkov, L. Gorelik
An implementation of a quantum computer based on space states in double quantum dots is discussed. There is no charge transfer in qubits during calculation, therefore, uncontrollab…
