Direct Fidelity Estimation for Generic Quantum States

2024 · arXiv (Cornell University)

Verifying the proper preparation of quantum states is essential in modern quantum information science. Various protocols have been developed to estimate the fidelity of quantum states produced by different parties. Direct fidelity estimation is a …

Localizing entanglement in high-dimensional states

2025 · arXiv (Cornell University)

In this work, we study the asymptotic behavior of protocols that localize entanglement in large multi-qubit states onto a subset of qubits by measuring the remaining qubits. We use the maximal average n-tangle that can …
