Generalized Reimpell-Werner Iteration
Shihao Ru, Bikun Li, Weibo Gao +1
Quantum measurements and channels determine how information is extracted, encoded, and transmitted in quantum protocols. Optimizing their performance often requires numerical metho…
High-Rank Encoding Can Improve Approximate Quantum Error Correction
Bikun Li, Liang Jiang
Conventional quantum-code constructions encode pure logical states as pure code states, but this restriction can sacrifice performance. We show that intrinsic encoding randomness c…
Enhancing Entanglement Purification with Shared Randomness
Allen Zang, Bikun Li, Xinan Chen +4
Entanglement purification protocols (EPPs) are essential for improving entanglement fidelity to support fault-tolerant distributed quantum information processing. Practical entangl…
Realistic Simulation of Quantum Repeater with Encoding and Classical Error Correction
Sagar Patange, Caitao Zhan, Bikun Li +4
Quantum repeaters are essential for scalable long-distance quantum networking. As quantum information processing moves toward fault-tolerant and error-corrected operations, it beco…
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 Entanglement Purification Circuit Design for Dual-Species Atom Arrays
Bikun Li, Daniel Dilley, Alvin Gonzales +6
Entanglement purification protocols (EPPs) are essential for generating high-fidelity entangled states in noisy quantum systems, enabling robust quantum networking and computation.…
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…
Optimality Condition for the Petz Map
Bikun Li, Zhaoyou Wang, Guo Zheng +2
In quantum error correction, the Petz map serves as a perfect recovery map when the Knill-Laflamme conditions are satisfied. Notably, while perfect recovery is generally infeasible…
Generalized Quantum Repeater Graph States
Bikun Li, Kenneth Goodenough, Filip Rozpędek +1
All-photonic quantum repeaters are essential for establishing long-range quantum entanglement. Within repeater nodes, reliably performing entanglement swapping is a key component o…
Detecting Errors in a Quantum Network with Pauli Checks
Alvin Gonzales, Daniel Dilley, Bikun Li +2
We apply the quantum error detection scheme Pauli check sandwiching (PCS) to quantum networks by turning it into a distributed multiparty protocol. PCS provides protection on the t…
