High-performance cavity-enhanced quantum memory with warm atomic cell

open access: yesNature Communications, 2022
Quantum memories usually suffer from a trade-off between efficiency and excess noise. Here, by exploiting the time-reversal approach for improving modes matching, the authors show a warm-atomic-cell-based cavity-enhanced memory with 67% efficiency and ...

Testing universality of Feynman-Tan relation in interacting Bose gases using high-order Bragg spectra

open access: yesLight: Science & Applications, 2023
The Feynman-Tan relation, obtained by combining the Feynman energy relation with the Tan’s two-body contact, can explain the excitation spectra of strongly interacting 39K Bose-Einstein condensate (BEC).

Deterministic and Efficient Quantum Key Distribution Using Entanglement Parity Bits and Ancillary Qubits

open access: yesIEEE Access, 2017
In this paper, we propose an efficient and deterministic quantum key distribution protocol for establishing a secret key between two untrusted users. In this protocol, a secret key is distributed to a sender and a receiver who share entangled states with
