Exploring postselection-induced quantum phenomena with time-bidirectional state formalism

Evgeniy O. Kiktenko

Here we present the time-bidirectional state formalism (TBSF) unifying in a general manner the standard quantum mechanical formalism with no postselection and the time-symmetrized…

Quantum communication protocols as a benchmark for quantum computers

A. A. Zhukov, E. O. Kiktenko, A. A. Elistratov +2

We point out that realization of quantum communication protocols in programmable quantum computers provides a deep benchmark for capabilities of real quantum hardware. Particularly…

Error estimation at the information reconciliation stage of quantum key distribution

E. O. Kiktenko, A. O. Malyshev, A. A. Bozhedarov +3

Quantum key distribution (QKD) offers a practical solution for secure communication between two distinct parties via a quantum channel and an authentic public channel. In this work…

Symmetric blind information reconciliation and hash-function-based verification for quantum key distribution

A. K. Fedorov, E. O. Kiktenko, A. S. Trushechkin

We consider an information reconciliation protocol for quantum key distribution (QKD). In order to correct down the error rate, we suggest a method, which is based on symmetric bli…

Bidirectional imperfect quantum teleportation with a single Bell state

E. O. Kiktenko, A. A. Popov, A. K. Fedorov

We present a bidirectional modification of the standard one-qubit teleportation protocol, where both Alice and Bob transfer noisy versions of their qubit states to each other by us…

Mutual information-energy inequality for thermal states of a bipartite quantum system

Aleksey Fedorov, Evgeny Kiktenko

In this work, we consider an upper bound for the quantum mutual information in thermal states of a bipartite quantum system. This bound is related with the interaction energy and l…

Multilevel superconducting circuits as two-qubit systems: Operations, state preparation, and entropic inequalities

E. O. Kiktenko, A. K. Fedorov, O. V. Man'ko +1

We theoretically study operations with a four-level superconducting circuit as a two-qubit system. Using a mapping on a two-qubit system, we show how to implement iSWAP gates and H…

Tomographic discord for a system of two coupled nanoelectric circuits

A. K. Fedorov, E. O. Kiktenko, O. V. Man'ko +1

We consider quantum correlations and quantum discord phenomena for two-qubit states with -type density matrices in the tomographic framework of quantum mechanics. By introducing…

Tomographic causal analysis of two-qubit states and tomographic discord

Evgeny Kiktenko, Aleksey Fedorov

We study a behavior of two-qubit states subject to tomographic measurement. We propose a novel approach to definition of asymmetry in quantum bipartite state based on its tomograph…

Quaternion representation and symplectic spin tomography

Aleksey Fedorov, Evgeny Kiktenko

Quantum tomography for continuous variables is based on the symplectic transformation group acting in the phase space. A particular case of symplectic tomography is optical tomogra…
