Circuit-based leakage-to-erasure conversion in a neutral atom quantum processor
Matthew N. H. Chow, Vikas Buchemmavari, Sivaprasad Omanakuttan +4
Leakage out of the computational subspace is a major limitation of current state-of-the-art neutral-atom quantum computers and a significant challenge for scalable systems. In a qu…
Entangling quantum logic gates in neutral atoms via the microwave-driven spin-flip blockade
Vikas Buchemmavari, Sivaprasad Omanakuttan, Yuan-Yu Jau +1
The Rydberg dipole-blockade has emerged as the standard mechanism to induce entanglement between neutral atom qubits. In these protocols, laser fields that couple qubit states to R…
High-Fidelity, Low-Loss State Detection of Alkali-Metal Atoms in Optical Tweezer Traps
Matthew N. H. Chow, Bethany J. Little, Yuan-Yu Jau
We demonstrate discrimination of ground-state hyperfine manifolds of a cesium atom in an optical tweezer using a simple probe beam with 99.91(2)% detection fidelity and 0.9(2)% det…
A Mølmer-Sørensen Gate with Rydberg-Dressed Atoms
Michael J. Martin, Yuan-Yu Jau, Jongmin Lee +3
Neutral atoms are building blocks of ground-up quantum many-body systems. Well-controlled and high-fidelity entangling gates are an essential component for realizing complex neutra…
Characterization of Suspended Membrane Waveguides towards a Photonic Atom Trap Integrated Platform
Michael Gehl, William Kindel, Nicholas Karl +10
We demonstrate an optical waveguide device, capable of supporting the high, in-vacuum, optical power necessary for trapping a single atom or a cold atom ensemble with evanescent fi…
Demonstration of a MOT in a Sub-Millimeter Membrane Hole
Jongmin Lee, Grant Biedermann, John Mudrick +2
We demonstrate the generation of a cold-atom ensemble within a sub-millimeter diameter hole in a transparent membrane, a so-called "membrane MOT". With a sub-Doppler cooling proces…
Enhanced cooperativity for quantum-nondemolition-measurement--induced spin squeezing of atoms coupled to a nanophotonic waveguide
Xiaodong Qi, Yuan-Yu Jau, Ivan H. Deutsch
We study the enhancement of cooperativity in the atom-light interface near a nanophotonic waveguide for application to quantum nondemolition (QND) measurement of atomic spins. Here…
Demonstration of the Jaynes-Cummings ladder with Rydberg-dressed atoms
Jongmin Lee, Michael J. Martin, Yuan-Yu Jau +3
We observe the nonlinearity of the Jaynes-Cummings (JC) ladder in the Autler-Townes spectroscopy of the hyperfine ground states for a Rydberg-dressed two-atom system. Here the role…
Arbitrary Dicke-State Control of Symmetric Rydberg Ensembles
Tyler Keating, Charles H. Baldwin, Yuan-Yu Jau +3
Symmetric ensembles of neutral atoms interacting via the Rydberg blockade are well-described by the Jaynes-Cummings Hamiltonian. We use this framework to study the problem of gener…
Robust quantum logic in neutral atoms via adiabatic Rydberg dressing
Tyler Keating, Robert L. Cook, Aaron Hankin +3
We study a scheme for implementing a controlled-Z (CZ) gate between two neutral-atom qubits based on the Rydberg blockade mechanism in a manner that is robust to errors caused by a…
Adiabatic quantum computation with Rydberg-dressed atoms
Tyler Keating, Krittika Goyal, Yuan-Yu Jau +3
We study an architecture for implementing adiabatic quantum computation with trapped neutral atoms. Ground state atoms are dressed by laser fields in a manner conditional on the Ry…
