Concentration-Free Quantum Kernel Learning in the Rydberg Blockade
Ayana Sarkar, Martin Schnee, Sangeeth Das Kallullathil +4
Quantum kernel methods (QKMs) offer an appealing framework for machine learning on near-term quantum computers. However, QKMs generically suffer from exponential concentration, req…

Unconventional early-time relaxation in the Rydberg chain
Martin Schnee, Roya Radgohar, Stefanos Kourtis
We show that unconventional relaxation dynamics of special initial states in one-dimensional arrays of Rydberg atoms produce non-generic decay of the initial-state survival probabi…
