Measurement-free code-switching for low overhead quantum computation using permutation invariant codes
Yingkai Ouyang, Yumang Jing, Gavin K. Brennen
Transversal gates on quantum error correction codes have been a promising approach for fault-tolerant quantum computing, but are limited by the Eastin-Knill no-go theorem. Existing…
Experimental Quantum Communication Overcomes the Rate-loss Limit without Global Phase Tracking
Lai Zhou, Jinping Lin, Yuan-Mei Xie +4
Secure key rate (SKR) of point-point quantum key distribution (QKD) is fundamentally bounded by the rate-loss limit. Recent breakthrough of twin-field (TF) QKD can overcome this li…
Twin-field quantum key distribution without optical frequency dissemination
Lai Zhou, Jinping Lin, Yumang Jing +1
Twin-field (TF) quantum key distribution (QKD) has rapidly risen as the most viable solution to long-distance secure fibre communication thanks to its fundamentally repeater-like r…
Quantum repeaters with encoding on nitrogen-vacancy center platforms
Yumang Jing, Mohsen Razavi
We investigate quantum repeater protocols that rely on three-qubit repetition codes using nitrogen-vacancy (NV) centers in diamond as quantum memories. NV centers offer a two-qubit…
Simple efficient decoders for quantum key distribution over quantum repeaters with encoding
Yumang Jing, Mohsen Razavi
We study the implementation of quantum key distribution (QKD) systems over quantum repeater infrastructures. We particularly consider quantum repeaters with encoding and compare th…
Quantum key distribution over quantum repeaters with encoding: Using Error Detection as an Effective Post-Selection Tool
Yumang Jing, Daniel Alsina Leal, Mohsen Razavi
We propose a post-selection technique, based on quantum error detection, for quantum key distribution (QKD) systems that run over quantum repeaters with encoding. In such repeaters…
Split spin-squeezed Bose-Einstein Condensates
Yumang Jing, Matteo Fadel, Valentin Ivannikov +1
We investigate and model the behaviour of split spin-squeezed Bose-Einstein condensates (BECs) system. In such a system, a spin-polarized BEC is first squeezed using a …
Correlation based entanglement criteria for bipartite systems
Yumang Jing, Qiongyi He, Tim Byrnes
We introduce a class of inequalities based on low order correlations of operators to detect entanglement in bipartite systems. The operators may either be Hermitian or non-Hermitia…
