Trapping potentials and quantum gates for microwave-dressed Rydberg atoms on an atom chip
Iason Tsiamis, Georgios Doultsinos, Andreas F. Tzortzakakis +5
Rydberg atoms in dc electric fields acquire static dipole moments. When the atoms are close to a surface producing an inhomogeneous electric field, such as by the adsorbates on an…
Multi-qubit Rydberg gates between distant atoms
Antonis Delakouras, Georgios Doultsinos, David Petrosyan
We propose an efficient protocol to realize multi-qubit gates in arrays of neutral atoms. The atoms encode qubits in the long-lived hyperfine sublevels of the ground electronic sta…
Fundamental error bound for entanglement generation between interacting Rydberg atoms
Georgios Doultsinos, Antonis Delakouras, David Petrosyan
We analytically derive the lower error bound for the preparation of any maximally entangled state of two atoms involving Rydberg-state interactions. This fundamental bound represen…
Quantum gates between distant atoms mediated by a Rydberg excitation antiferromagnet
Georgios Doultsinos, David Petrosyan
We present a novel protocol for implementing quantum gates between distant atomic qubits connected by an array of neutral atoms that play the role of a quantum bus. The protocol is…
Fast measurements and multiqubit gates in dual species atomic arrays
D. Petrosyan, S. Norrell, C. Poole +1
We propose and analyze an approach for fast syndrome measurements in an array of rubidium and cesium atomic qubits. The scheme works by implementing an inter-species $\textsf{CNOT}…
