Neutral atom quantum computing
M. Saffman
Neutral atom qubits are one of the leading approaches for implementation of a large scale quantum computer. The original proposals for neutral atom qubits were formulated more than…
Strategic Plan for Neutral Atom Quantum Computation
Adrian J. Menssen, Tout Wang, Michael Gullans +53
We present a strategic plan for neutral atom quantum computation, bringing together hardware development and theory advancements to achieve the goal of practical quantum advantage.…
Fault-tolerant quantum computation with static atomic buses
Matteo Bergonzoni, Laura Pecorari, Sam Norrell +3
Efficient quantum error correction and fault-tolerant quantum computing require scalable, high-fidelity long-range connectivity. In neutral-atom quantum computers, this is commonly…
Entangling gate performance and fidelity limits with neutral atom Förster resonances
S. A. Norrell, Y. Shen, M. Saffman +1
Neutral-atom entangling gates are commonly analyzed with a single effective Rydberg-pair state, but near Förster resonances the pair manifold contains resonantly coupled interactio…
Demonstration of a Logical Architecture Uniting Motion and In-Place Entanglement
Rich Rines, Benjamin Hall, Mariesa H. Teo +35
We demonstrate a logical neutral atom architecture that integrates atom motion with in-place entanglement to achieve lower overheads than entangling-zone approaches. Using a 114-qu…
Experimental observation of subabsorption
D. C. Gold, U. Saglam, S. Carpenter +5
We predict and experimentally demonstrate a new type of collective (cooperative) coupling effect where a disordered atomic ensemble absorbs light with a rise-time longer (i. e., at…
Quantum computing with atomic qubit arrays: confronting the cost of connectivity
M. Saffman
These notes present a review of the status of quantum computing with arrays of neutral atom qubits, an approach which has demonstrated remarkable progress in the last few years. Sc…
Fault-Tolerant Operation and Materials Science with Neutral Atom Logical Qubits
Matt. J. Bedalov, Matt Blakely, Peter. D. Buttler +27
We report on the fault-tolerant operation of logical qubits on a neutral atom quantum computer, with logical performance surpassing physical performance for multiple circuits inclu…
Multi-scale architecture for fast optical addressing and control of large scale qubit arrays
T. M. Graham, E. Oh, M. Saffman
We present a technique for rapid site-selective control of the quantum state of particles in a large array using a combination of a fast deflector (e.g. an acousto-optic deflector)…
Speed, retention loss, and motional heating of atoms in an optical conveyor belt
G. T. Hickman, M. Saffman
The problem of high-speed transport for cold atoms with minimal heating has received considerable attention in theory and experiment. Much theoretical work has focused on solutions…
Analysis of a controlled phase gate using circular Rydberg states
T. Xia, X. L. Zhang, M. Saffman
We propose and analyze the implementation of a two qubit quantum gate using circular Rydberg states with maximum orbital angular momentum. The intrinsic quantum gate error is limit…
Coherent control of mesoscopic atomic ensembles for quantum information
I. I. Beterov, M. Saffman, V. P. Zhukov +8
We discuss methods for coherently controlling mesoscopic atomic ensembles where the number of atoms varies randomly from one experimental run to the next. The proposed schemes are…
A crossed vortex bottle beam trap for single-atom qubits
G. Li, S. Zhang, L. Isenhower +2
We demonstrate trapping and quantum state control of single Cesium atoms in a 532 nm wavelength bottle beam trap. The three dimensional trap is formed by crossing two unit charge v…
Doppler-free, Multi-wavelength Acousto-optic deflector for two-photon addressing arrays of Rb atoms in a Quantum Information Processor
Sangtaek Kim, Robert R. Mcleod, Mark Saffman +1
We demonstrate a dual wavelength acousto-optic deflector (AOD) designed to deflect two wavelengths to the same angles by driving with two RF frequencies. The AOD is designed as a b…
