Enhanced Weak-Value Amplification via Photon Recycling

2021 · Physical Review Letters

In a quantum-noise limited system, weak-value amplification using postselection normally does not produce more sensitive measurements than standard methods for ideal detectors: the increased weak value is compensated by the reduced power due to the …

Faithful Quantum Teleportation via a Nanophotonic Nonlinear Bell State Analyzer

2025 · Physical Review Letters

Quantum networking protocols, including quantum teleportation and entanglement swapping, use linear-optical Bell state measurements for heralding the distribution and transfer of quantum information. However, a linear-optical Bell state measurement requires identical photons and is susceptible …
