Quantum simulation of transverse Ising models with Rydberg atoms
Quantum Isingmodels are canonicalmodels for the study of quantumphase transitions (Sachdev 1999QuantumPhase Transitions (Cambridge: CambridgeUniversity Press)) and are the underlying concept formany analogue quantumcomputing and quantum annealing ideas (Tanaka et al Quantum SpinGlasses, Annealing andComputation (Cambridge: CambridgeUniversity Press)). Here we focus on the implementation offinit...
متن کاملQuantum information with Rydberg atoms
Rydberg atoms with principal quantum number n 1 have exaggerated atomic properties including dipole-dipole interactions that scale as n4 and radiative lifetimes that scale as n3. It was proposed a decade ago to take advantage of these properties to implement quantum gates between neutral atom qubits. The availability of a strong long-range interaction that can be coherently turned on and off is...
متن کاملA coherent quantum annealer with Rydberg atoms
There is a significant ongoing effort in realizing quantum annealing with different physical platforms. The challenge is to achieve a fully programmable quantum device featuring coherent adiabatic quantum dynamics. Here we show that combining the well-developed quantum simulation toolbox for Rydberg atoms with the recently proposed Lechner-Hauke-Zoller (LHZ) architecture allows one to build a p...
متن کاملCollective quantum jumps of Rydberg atoms.
We study an open quantum system of atoms with a long-range Rydberg interaction, laser driving, and spontaneous emission. Over time, the system occasionally jumps between a state of low Rydberg population and a state of high Rydberg population. The jumps are inherently collective, and in fact, exist only for a large number of atoms. We explain how entanglement and quantum measurement enable the ...
متن کاملSimulation of coherent interactions between Rydberg atoms
The results of a theoretical investigation of the coherent interaction between many Rydberg atoms are reported. The atoms are assumed to move very little during the time range we investigate. We describe the basic interaction between atoms and show that (contrary to previous theoretical studies) the interaction between the atoms can be coherent. The band structure for a perfect lattice of atoms...
