Observation of interaction induced Rydberg blockade and local spin freezing in an NMR quantum simulator

ORAL

Abstract

We experimentally emulate interaction induced blockade and local spin freezing in two and three spin-1/2 nuclear spin-systems using Nuclear Magnetic Resonance (NMR) architecture. These phenomena are identical to the Rydberg blockade and Rydberg biased freezing, which are facilitated by strong inter-particle interactions. In addition, we probe quantum correlations between the qubits under blockade and freezing phenomena using quantum discord. Such studies open up interesting quantum-information perspectives in simulating atomic interactions via NMR architecture.
