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…
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…
