چکیده

Fault-tolerant implementation of quantum gates is one preconditions for realizing computation. The platform Rydberg atoms the most promising candidates achieving We propose to implement a controlled-$Z$ gate on where an amplitude-modulated field employed induce antiblockade. Gate robustness against fluctuations in Rydberg-Rydberg interaction can be largely enhanced by adjusting field. Furthermore, we introduce Landau-Zener-St\"{u}ckelberg transition target atom so as improve resilience deviation time and drift pulse amplitude. With feasible experimental parameters, achieve with low fidelity errors caused atomic decay, interatomic dipole-dipole force, Doppler effects. Finally, generalize scheme into multiqubit cases, resilient phase obtained step unchanged number qubits increases.

Quantum 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...

Coherent states of the driven Rydberg atom: Quantum-classical correspondence of periodically driven systems

A methodology to calculate generalized coherent states for a periodically driven system is presented. We study wave packets constructed as a linear combination of suitable Floquet states of the three-dimensional Rydberg atom in a microwave field. The driven coherent states show classical space localization, spreading, and revivals and remain localized along the classical trajectory. The microwa...

Driven Rydberg atoms reveal quartic level repulsion.

The dynamics of Rydberg states of a hydrogen atom subjected simultaneously to uniform static electric field and two microwave fields with commensurate frequencies is considered in the range of small field amplitudes. In the certain range of the parameters of the system the classical secular motion of the electronic ellipse reveals chaotic behavior. Quantum mechanically, when the fine structure ...

Conductance fluctuations in microwave-driven Rydberg atoms

– We draw and quantitatively support a parallel between conductance fluctuations in one-dimensional disordered solids and fluctuations of lifetimes of hydrogen atoms in microwave fields. In particular, we numerically analyze the statistics of scaled atomic resonance widths in the localized regime and we find a lognormal distribution, quantitatively consistent with the theory of Anderson localiz...

Collective 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 ...
