Entanglement Distillation and Swapping Scheduling in Quantum Repeaters with Noisy Memories
Siddharth Chander, Xinan Chen, Allen Zang
Entanglement distillation and entanglement swapping have been extensively studied assuming perfect quantum memories. However, near-term quantum networks will be fundamentally limit…
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…
Routing Entanglement in Complex Quantum Networks Using GHZ States
Xin-An Chen, Caitao Zhan, Joaquin Chung +1
Distributing entanglement to distant parties in a network is a central task in quantum information processing and quantum networking. The sensitivity of entangled states to loss ne…
No-Go Theorems for Universal Entanglement Purification
Allen Zang, Xinan Chen, Eric Chitambar +2
An entanglement purification protocol (EPP) aims to transform multiple noisy entangled states into a single entangled state with higher fidelity. In this work we consider EPPs that…
Entanglement Purification in Quantum Networks: Guaranteed Improvement and Optimal Time
Allen Zang, Xin-An Chen, Eric Chitambar +2
While the concept of entanglement purification protocols (EPPs) is straightforward, the integration of EPPs in network architectures requires careful performance evaluations and op…
