Characterizing noise correlation and enhancing coherence via qubit motion
Fundamental Research, 2021 The identification of spacial noise correlation is of critical importance in developing error-corrected quantum devices, but it has barely been studied so far. In this work, we utilize an effective method called qubit motion, to efficiently determine the

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.

Quantum-enhanced radiometry via approximate quantum error correction
Nature Communications, 2022 Exotic quantum states can be advantageous for sensing, but are very fragile, so that some form of quantum error correction is needed. Here, the authors show how approximate QEC helps overcoming decoherence due to noise when measuring the excitation ...

Strategies for Positive Partial Transpose (PPT) States in Quantum Metrologies with Noise
, 2021 Quantum metrology overcomes standard precision limits and has the potential to play a key role in quantum sensing. Quantum mechanics, through the Heisenberg uncertainty principle, imposes limits on the precision of measurements.

Strategies for achieving high key rates in satellite-based QKD
npj Quantum Information, 2021 Quantum key distribution (QKD) is a pioneering quantum technology on the brink of widespread deployment. Nevertheless, the distribution of secret keys beyond a few 100 km at practical rates remains a major challenge.
