Quantum Advantage in Distributed Sensing with Noisy Quantum Networks
Allen Zang, Alexander Kolar, Alvin Gonzales +5
We show that quantum advantage in distributed sensing can be achieved with noisy quantum networks which only distribute noisy entangled states. We derive a closed-form expression o…
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…
Analytical Performance Estimations for Quantum Repeater Network Scenarios
Allen Zang, Joaquin Chung, Rajkumar Kettimuthu +2
Quantum repeater chains will form the backbone of future quantum networks that distribute entanglement between network nodes. Therefore, it is important to understand the entanglem…
Provable Optimality of the Square-Tooth Atomic Frequency Comb Quantum Memory
Allen Zang, Martin Suchara, Tian Zhong
Atomic frequency comb (AFC) quantum memories are a promising technology for quantum repeater networks because they enable multi-mode, long-time, and high-fidelity storage of photon…
