Assembling a Bose-Hubbard superfluid from tweezer-controlled single atoms
William J. Eckner, Theodor Lukin Yelin, Alec Cao +4
Quantum simulation relies on the preparation and control of low-entropy many-body systems to reveal the behavior of classically intractable models. The development of new approache…
A high optical access cryogenic system for Rydberg atom arrays with a 3000-second trap lifetime
Zhenpu Zhang, Ting-Wei Hsu, Ting You Tan +4
We present an optical tweezer array of Rb atoms housed in an cryogenic environment that successfully combines a 4 K cryopumping surface, a <50 K cold box surrounding the ato…
Autoionization-enhanced Rydberg dressing by fast contaminant removal
Alec Cao, Theodor Lukin Yelin, William J. Eckner +2
Rydberg dressing is a powerful tool for entanglement generation in long-lived atomic states. While already employed effectively in several demonstrations, a key challenge for this…
Multi-qubit gates and Schrödinger cat states in an optical clock
Alec Cao, William J. Eckner, Theodor Lukin Yelin +8
Many-particle entanglement is a key resource for achieving the fundamental precision limits of a quantum sensor. Optical atomic clocks, the current state-of-the-art in frequency pr…
Long-range-enhanced surface codes
Yifan Hong, Matteo Marinelli, Adam M. Kaufman +1
The surface code is a quantum error-correcting code for one logical qubit, protected by spatially localized parity checks in two dimensions. Due to fundamental constraints from spa…
