We present a toolbox to probe quantum many-body states implemented on Rydberg-atoms quantum hardware via randomized measurements. We illustrate the efficacy of this measurement toolbox in the context of probing entanglement, via the estimation of the

We experimentally realize a Peierls phase in the hopping amplitude of excitations carried by Rydberg atoms, and observe the resulting characteristic chiral motion in a minimal setup of three sites. Our demonstration relies on the intrinsic spin-orbit

We report on the realization of large assembled arrays of more than 300 single 87Rb atoms trapped in optical tweezers in a cryogenic environment at ∼4 K. For arrays with Na=324 atoms, the assembly process results in defect-free arrays in ∼37% of

Generating an arbitrary spin exchange between Rydberg atoms through Floquet engineering

Autor: Shai Tsesses, Anna Keselman, Antoine Browaeys, Thierry Lahaye

Publikováno v: Quantum 2.0 Conference and Exhibition.

We propose a method to engineer an arbitrary effective spin exchange Hamiltonian in arrays of Rydberg atoms and verify its experimental viability through simulations of induced anti-symmetric exchange interaction between 3 atoms.

Quantum simulation using synthetic systems is a promising route to solve outstanding quantum many-body problems in regimes where other approaches, including numerical ones, fail1. Many platforms are being developed towards this goal, in particular ba
