Versatile Atomic Magnetometry Assisted by Bayesian Inference

2022-04-05T17:41:00+02:00Tags: , |

Authors: Puebla, R.; Ban, Y.; Haase, J. F.; Plenio, M. B.; Paternostro, M.; Casanova, J. Journal: PHYSICAL REVIEW APPLIED Publication date: 2021/08/25 DOI: 10.1103/PhysRevApplied.16.024044 Abstract: Quantum sensors typically translate external fields into a periodic response whose frequency is then determined by analyses performed in Fourier space. This allows for a linear inference of the parameters [...]

Three-Josephson junctions flux qubit couplings

2021-11-29T20:21:00+01:00Tags: , |

Authors: Hita-Perez, Maria; Jauma, Gabriel; Pino, Manuel; Garcia-Ripoll, Juan Jose Journal: APPLIED PHYSICS LETTERS Publication date: 2021/11/29 DOI: 10.1063/5.0069530 Abstract: We analyze the coupling of two flux qubits with a general many-body projector into the low-energy subspace. Specifically, we extract the effective Hamiltonians that controls the dynamics of two qubits when they are coupled via [...]

Quantum Control of Frequency-Tunable Transmon Superconducting Qubits

2021-02-12T10:07:56+01:00Tags: , |

Authors: Garcia-Ripoll, J. J.; Ruiz-Chamorro, A.; Torrontegui, E. Contribution: Article Journal: PHYSICAL REVIEW APPLIED Publication date: 2020/10/20 DOI: 10.1103/PhysRevApplied.14.044035 Abstract: In this work we analyze the implementation of a control-phase gate through the resonance between the vertical bar 11 > and vertical bar 20 > states of two statically coupled transmons. We find that there are [...]
