Passive Environment-Assisted Quantum Communication
Evelyn Voss, Bikun Li, Zhaoyou Wang +1
As quantum information systems mature, efficient and coherent transfer of quantum information through noisy channels becomes increasingly important. We examine how passive environm…
InterQnet: A Heterogeneous Full-Stack Approach to Co-designing Scalable Quantum Networks
Joaquin Chung, Daniel Dilley, Ely Eastman +21
Quantum communications have progressed significantly, moving from a theoretical concept to small-scale experiments to recent metropolitan-scale demonstrations. As the technology ma…
Efficient Measurement of Bosonic Non-Gaussianity
Kaifeng Bu, Bikun Li
Non-Gaussian states are essential resources in quantum information processing. In this work, we investigate methods for quantifying bosonic non-Gaussianity in many-body systems. Bu…
Constant-Overhead Fault-Tolerant Bell-Pair Distillation using High-Rate Codes
J. Pablo Bonilla Ataides, Hengyun Zhou, Qian Xu +4
We present a fault-tolerant Bell-pair distillation scheme achieving constant overhead through high-rate quantum low-density parity-check (qLDPC) codes. Our approach maintains a con…
Space-time Peer-to-Peer Distribution of Multi-party Entanglement for Any Quantum Network
Yuexun Huang, Xiangyu Ren, Bikun Li +3
Graph states are a class of important multiparty entangled states, of which bell pairs are the special case. Realizing a robust and fast distribution of arbitrary graph states in t…
