Gate-based Readout and Cooling of Neutral Atoms
Richard Bing-Shiun Tsai, Lewis R. B. Picard, Xiangkai Sun +3
Neutral atom arrays have seen tremendous progress in quantum simulation, quantum metrology, and fault-tolerant quantum computing. However, hardware constraints such as atom loss an…
Experimental observation of conformal field theory spectra
Xiangkai Sun, Yuan Le, Stephen Naus +6
Conformal field theories (CFTs) feature prominently in high-energy physics, statistical mechanics, and condensed matter. For example, CFTs govern emergent universal properties of s…
Erasure-cooling, control, and hyper-entanglement of motion in optical tweezers
Adam L. Shaw, Pascal Scholl, Ran Finkelstein +3
Coherently controlling the motion of single atoms in optical tweezers would enable new applications in quantum information science. To demonstrate this, we first prepare atoms in t…
Benchmarking and fidelity response theory of high-fidelity Rydberg entangling gates
Richard Bing-Shiun Tsai, Xiangkai Sun, Adam L. Shaw +2
The fidelity of entangling operations is a key figure of merit in quantum information processing, especially in the context of quantum error correction. High-fidelity entangling ga…
Universal quantum operations and ancilla-based readout for tweezer clocks
Ran Finkelstein, Richard Bing-Shiun Tsai, Xiangkai Sun +6
Enhancing the precision of measurements by harnessing entanglement is a long-sought goal in the field of quantum metrology. Yet attaining the best sensitivity allowed by quantum th…
