Quantum repeaters based on Rydberg-blockade coupled atomic ensembles

Yang Han, Bing He, Khabat Heshami +2

We propose a scheme for realizing quantum repeaters with Rydberg-blockade coupled atomic ensembles, based on a recently proposed collective encoding strategy. Rydberg-blockade medi…

Robust quantum repeater with atomic ensembles against phase and polarization instability

Ming Gao, Lin-Mei Liang, Cheng-Zu Li +1

We propose an alternative scheme for quantum repeater without phase stabilization and polarization calibration of photons transmitted over long-distance channel. We introduce time-…

Quantum Coherence Effects in Four-level Diamond Atomic System

Bao-Quan Ou, Lin-Mei Liang, Cheng-Zu Li

A symmetric four-level closed-loop type (the diamond structure) atomic system driven by four coherent optical fields is investigated. The system shows rich quantum i…

Long distance quantum key distribution without decoy state

Shi-Hai Sun, Cheng-Zu Li

We present a method without decoy state to estimate faithfully and efficiently the yield and quantum bit error rate of single photon pulse for BB84 protocol. The numerical calculat…

Coherence Induced by Incoherent Pumping Field and Decay Process in Three-level Type Atomic System

Bao-Quan Ou, Lin-Mei Liang, Cheng-Zu Li

Following the method of Victor V. Kozlov et al.[PhysRevA. 74. 063829],we inspect the coherence induced by incoherent pump and spontaneous decay process in type three-level atom…
