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…
Heisenberg-limited Bayesian phase estimation with low-depth digital quantum circuits
Su Direkci, Ran Finkelstein, Manuel Endres +1
Optimal phase estimation protocols require complex state preparation and readout schemes, generally unavailable or unscalable in many quantum platforms. We develop and analyze a sc…
Experimental signatures of Hilbert-space ergodicity: Universal bitstring distributions and applications in noise learning
Adam L. Shaw, Daniel K. Mark, Joonhee Choi +4
Systems reaching thermal equilibrium are ubiquitous. For classical systems, this phenomenon is typically understood statistically through ergodicity in phase space, but translating…
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…
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…
