Ultra-violet (UV) and near-UV wavelengths are necessary for many important optical transitions for quantum technologies and various sensing mechanisms for biological and chemical d…
Circuit-based leakage-to-erasure conversion in a neutral atom quantum processor
Matthew N. H. Chow, Vikas Buchemmavari, Sivaprasad Omanakuttan +4
Leakage out of the computational subspace is a major limitation of current state-of-the-art neutral-atom quantum computers and a significant challenge for scalable systems. In a qu…
