Benchmarking highly entangled states on a 60-atom analog quantum simulator
Adam L. Shaw, Zhuo Chen, Joonhee Choi +6
Quantum systems have entered a competitive regime where classical computers must make approximations to represent highly entangled quantum states. However, in this beyond-classical…
Erasure conversion in a high-fidelity Rydberg quantum simulator
Pascal Scholl, Adam L. Shaw, Richard Bing-Shiun Tsai +3
Minimizing and understanding errors is critical for quantum science, both in noisy intermediate scale quantum (NISQ) devices and for the quest towards fault-tolerant quantum comput…
Multi-ensemble metrology by programming local rotations with atom movements
Adam L. Shaw, Ran Finkelstein, Richard Bing-Shiun Tsai +4
Current optical atomic clocks do not utilize their resources optimally. In particular, an exponential gain in sensitivity could be achieved if multiple atomic ensembles were to be…
