Proposal and proof-of-principle demonstration of non-destructive detection of photonic qubits using a Tm:LiNbO3 waveguide

Abstract

Rare-earth doped crystals are a promising platform for developing quantum devices. Here, Sinclair et al. propose and demonstrate a concept for non-destructive detection of photonic qubits using solid-state waveguides, which could help reduce signal losses in quantum information processing.
