Optimal high-dimensional entanglement concentration in the bipartite scenario

2023 · arXiv (Cornell University)

Considering pure quantum states, entanglement concentration is the procedure where from $N$ copies of a partially entangled state, a single state with higher entanglement can be obtained. Getting a maximally entangled state is possible for …

Near-optimal pure state estimation with adaptive Fisher-symmetric measurements

2024 · arXiv (Cornell University)

Quantum state estimation is important for various quantum information processes, including quantum communications, computation, and metrology, which require the characterization of quantum states for evaluation and optimization. We present a three-stage adaptive method for estimating …
