Destroying and Preserving Measurement Incompatibility over a Quantum Channel
Eric Chitambar, Yujie Zhang
A quantum channel is called incompatibility-breaking if it always destroys the incompatibility of quantum measurements. On the other extreme are incompatibility-preserving channels…
Universal Improvement of Channel Fidelity via Entanglement Assistance
Xinan Chen, Eric Chitambar
Communication using quantum channels generally requires encoding and decoding on many identical uses of a quantum channel. In practical settings, decoherence may severely limit our…
Compatibility of quantum instruments
Chloe Kim, Yujie Zhang, Eric Chitambar +2
Measurement compatibility asks whether a family of quantum measurements can be simulated by one parent measurement followed by classical post-processing. We extend this measurement…
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…
