Authors: Hita-Perez, Maria; Jauma, Gabriel; Pino, Manuel; Garcia-Ripoll, Juan Jose Journal: PHYSICAL REVIEW APPLIED Publication date: 2022/01/24 DOI: 10.1103/PhysRevApplied.17.014028 Abstract: A flux qubit can interact strongly when it is capacitively coupled to other circuit elements. This interaction can be separated into two parts, one acting on the qubit subspaces and one in which excited states [...]
Authors: Penas, Guillermo F.; Puebla, Ricardo; Ramos, Tomas; Rabl, Peter; Jose Garcia-Ripoll, Juan Journal: PHYSICAL REVIEW APPLIED Publication date: 2022/05/24 DOI: 10.1103/PhysRevApplied.17.054038 Abstract: We propose a realistic setup, inspired by already existing experiments, within which we develop a general formalism for the implementation of distributed quantum gates. Mediated by a quantum link that establishes a [...]
Authors: Gomez-Leon, Alvaro; Luis, Fernando; Zueco, David Journal: PHYSICAL REVIEW APPLIED Publication date: 2022/06/14 DOI: 10.1103/PhysRevApplied.17.064030 Abstract: We study the physics of a magnetic molecule described by a ???giant??? spin with multiple (d > 2) spin states interacting with the quantized cavity field produced by a superconducting resonator. By means of the input-output formalism, we [...]

Journal: PHYSICAL REVIEW APPLIED Publication date: 2022/08/17 DOI: 10.1103/PhysRevApplied.18.024048 Abstract: Current noise levels in physical realizations of qubits and quantum operations limit the applicability of conventional methods to characterize entanglement. In this adverse scenario, we follow a quantum variational approach to estimate the [...]

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. [...]

Journal: PHYSICAL REVIEW APPLIED Publication date: 2021/02/23 DOI: 10.1103/PhysRevApplied.15.024054 Abstract: The conventional approach to perform two-qubit gate operations in trapped ions relies on exciting the ions on motional sidebands with laser light, which is an inherently slow [...]
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 [...]

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 [...]
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 [...]
