Cloud-Accessible, Programmable Quantum Simulator Based on Two-Dimensional Neutral Atom Arrays

Florian Huber, Jesse Amato-Grill, Alexei Bylinskii +6 more

Neutral atom arrays recently emerged as one the leading platforms for large-scale quantum computing and simulations [1, 2]. These systems offer a variety of possible qubit encodings with long coherence times along with exceptional programmability and reconfigurability of the array geometry and qubit connectivity. In addition, strong, highly coherent coupling between the qubits can be achieved using Rydberg states of the atoms. QuEra provides a cloud-accessible, programmable 256-qubit quantum simulator based on a two-dimensional array of Rubidium-87 atoms in reconfigurable optical tweezers.Neutral atom arrays recently emerged as one the leading platforms for large-scale quantum computing and simulations [1, 2].

Subradiant Decay in 2D and 3D Atomic Arrays

Nicola Piovella, Romain Bachelard

Subradiance is a phenomenon where coupled emitters radiate light at a slower rate than independent ones. While its observation was first reported in disordered cold atom clouds, ordered subwavelength arrays of emitters have emerged as promising platforms to design highly cooperative optical properties based on dipolar interactions. In this work we characterize the eigenmodes of 2D and 3D regular arrays, using a method which can be used for both infinite and very large systems. In particular, we show how finite-size effects impact the lifetimes of these large arrays. Our results may have interesting applications for quantum memories and topological effects in ordered atomic arrays.Subradiance is a phenomenon where coupled emitters radiate light at a slower rate than independent ones.

Controlling quantum many-body dynamics in driven Rydberg atom arrays

Bluvstein, D, Omran, A, Levine, H +12 more

Dynamic stabilization of an array Large-scale systems comprising one-dimensional chains and two-dimensional arrays of excited atoms held in a programmable optical lattice are a powerful platform with which to simulate emergent phenomena. Bluvstein et al. built an array of up to 200 Rydberg atoms and subjected the system to periodic excitation. Under such driven excitation, they found that the array of atoms stabilized, freezing periodically into what looked like time crystals. Understanding and controlling the dynamic interactions in quantum many-body systems lies at the heart of contemporary condensed matter physics and the exotic phenomena that can occur.
