2021-10-27T10:46:59+02:00Tags: , , , |

Authors: Hernandez, Marta I.; Bartolomei, Massimiliano; Campos-Martinez, Jose Journal: NANOMATERIALS Publication date: 2021/01/01 DOI: 10.3390/nano11010073 Abstract: We report accurate quantum calculations of the sieving of Helium atoms by two-dimensional (2D) graphtriyne layers with a new interaction potential. Thermal rate constants and permeances in an ample temperature range are computed and compared for both Helium isotopes. [...]

Authors: Dolezal, Jiri; Merino, Pablo; Svec, Martin Journal: APPLIED PHYSICS LETTERS Publication date: 2021/05/10 DOI: 10.1063/5.0048476 Abstract: Constant amplitude bias modulation over a broad range of microwave frequencies is a prerequisite for application in high-resolution spectroscopic techniques in a tunnel junction, e.g., electron spin resonance spectroscopy or optically detected paramagnetic resonance. Here, we present an [...]

A perspective on scaling up quantum computation with molecular spins

Authors: Carretta, S.; Zueco, D.; Chiesa, A.; Gomez-Leon, A.; Luis, F. Journal: APPLIED PHYSICS LETTERS Publication date: 2021/06/14 DOI: 10.1063/5.0053378 Abstract: Artificial magnetic molecules can contribute to progressing toward large scale quantum computation by (a) integrating multiple quantum resources and (b) reducing the computational costs of some applications. Chemical design, guided by theoretical proposals, allows [...]

Versatile Atomic Magnetometry Assisted by Bayesian Inference

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 [...]

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 [...]
