Quantum Information Scrambling in Non-Markovian Open Quantum System. [PDF]
Entropy (Basel), 2022 In this paper, we investigate the dynamics of a spin chain whose two end spins interact with two independent non-Markovian baths by using the non-Markovian quantum state diffusion (QSD) equation approach.

Quantum Information of the Aharanov-Bohm Ring with Yukawa Interaction in the Presence of Disclination. [PDF]
Entropy (Basel), 2022 We investigate quantum information by a theoretical measurement approach of an Aharanov–Bohm (AB) ring with Yukawa interaction in curved space with disclination. We obtained the so-called Shannon entropy through the eigenfunctions of the system.

Switching and Swapping of Quantum Information: Entropy and Entanglement Level. [PDF]
Entropy (Basel), 2021 Information switching and swapping seem to be fundamental elements of quantum communication protocols. Another crucial issue is the presence of entanglement and its level in inspected quantum systems. In this article, a formal definition of the operation

Towards practical quantum computers: transmon qubit with a lifetime approaching 0.5 milliseconds
npj Quantum Information, 2022 Here we report a breakthrough in the fabrication of a long lifetime transmon qubit. We use tantalum films as the base superconductor. By using a dry etching process, we obtained transmon qubits with a best T 1 lifetime of 503 μs. As a comparison, we also
