Entanglement is an essential ingredient for quantum information processing, but its fragility hampers its application in practical scenarios. We experimentally demonstrate quantum sensing in a lossy and noisy environment, and show that a performance enhancement over the best classical system is achievable in spite of the entanglement-breaking background.

Pre-selected quantum nodes (diamond micro-waveguides containing single negatively charged nitrogen vacancy centers) are deterministically integrated into low-loss silicon nitride waveguides. Each quantum memory node efficiently couples into the single-mode waveguide and exhibits long spin coherence times.

“The iQuISE program represents a bold step forward to coalesce and cohere the education and research training that will produce a new generation of quantum information researchers for our nation.”
