High-fidelity quantum teleportation through noisy channels via weak measurement and environment-assisted measurement

2022 · arXiv (Cornell University)

A perfect teleportation protocol requires pure maximally shared entangled states. While in reality the shared entanglement is severely degraded due to the inevitable interaction with the noisy environment, which leads to mixed entangled state and …

Quantum state tomography of multi-qubit systems — a comparative study

2022 · International Journal of Quantum Information

Multi-qubit state tomography is a key problem in quantum information technology, which has been studied extensively. In this work, we focus on multi-qubit state tomography based on neural network estimators and typical conventional estimation approaches. …
