A concise review of Rydberg atom based quantum computation and quantum simulation

Abstract

Quantum information processing based on Rydberg atoms emerged as a promising direction two decades ago. Recent experimental and theoretical progresses have shined exciting light on this avenue. In this concise review, we will briefly introduce the basics of Rydberg atoms and their recent applications in associated areas of neutral atom quantum computation and simulation. We shall also include related discussions on quantum optics with Rydberg atomic ensembles, which are increasingly used to explore quantum computation and quantum simulation with photons.

Quantum evolution kernel : Machine learning on graphs with programmable arrays of qubits

“…Arrays of individual neutral atoms trapped in optical tweezers [41][42][43][44][45][46][47][48][49][50] have emerged as a promising platform for quantum information processing. By promoting the atoms to so-called Rydberg states, they behave as huge electric dipoles and experience dipole-dipole interactions that map into spin Hamiltonians.…”

Pulser: An open-source package for the design of pulse sequences in programmable neutral-atom arrays

“…Individual neutral atoms trapped in optical tweezers [1][2][3][4][5][6][7][8][9][10] have emerged as a powerful platform for quantum information processing. In those systems, one uses the strong interaction between atoms excited to a Rydberg state to generate entanglement.…”
