Optimal scheme for distributed quantum metrology
Zhiyao Hu, Allen Zang, Jianwei Wang +4
Optimal strategies for local quantum metrology -- including the preparation of optimal probe states, implementation of optimal control and measurement strategies, are well establis…
PhotonIDs: ML-Powered Photon Identification System for Dark Count Elimination
Karl C. Linne, Sho Uemura, Yue Ji +6
Reliable single photon detection is the foundation for practical quantum communication and networking. However, today's superconducting nanowire single photon detector(SNSPD) inher…
SQuaD: Smart Quantum Detection for Photon Recognition and Dark Count Elimination
Karl C. Linne, Sho Uemura, Yue Ji +5
Quantum detectors of single photons are an essential component for quantum information processing across computing, communication and networking. Today's quantum detection system,…
Enhancing Noisy Quantum Sensing by GHZ State Partitioning
Allen Zang, Tian-Xing Zheng, Peter C. Maurer +3
Presence of harmful noise is inevitable in entanglement-enhanced sensing systems, requiring careful allocation of resources to optimize sensing performance in practical scenarios.…
Quantum secret sharing in a triangular superconducting quantum network
Haoxiong Yan, Allen Zang, Joel Grebel +11
We present a three-node quantum communication testbed with a triangular topology, each side of the triangle formed by a 1.3-meter-long transmission line. We demonstrate state trans…
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…
