Construct validity of the anxiety sensitivity index-3 in clinical samples
2012
"Using two clinical samples of patients, the presented studies examined the construct validity of the recently revised Anxiety Sensitivity Index-3 (ASI-3). Confirmatory factor analyses established a clear three-factor structure that corresponds to the postulated subdivision of the construct into correlated somatic, social, and cognitive components. Participants with different primary clinical diagnoses differed from each other on the ASI-3 subscales in theoretically meaningful ways. Specifically, the ASI-3 successfully discriminated patients with anxiety disorders from patients with nonanxiety disorders. Moreover, patients with panic disorder or agoraphobia manifested more somatic concerns …
Entanglement Swapping between Discrete and Continuous Variables
2014
We experimentally realize "hybrid" entanglement swapping between discrete-variable (DV) and continuous-variable (CV) optical systems. DV two-mode entanglement as obtainable from a single photon split at a beam splitter is robustly transferred by means of efficient CV entanglement and operations, using sources of squeezed light and homodyne detections. The DV entanglement after the swapping is verified without post-selection by the logarithmic negativity of up to 0.28$\pm$0.01. Furthermore, our analysis shows that the optimally transferred state can be post-selected into a highly entangled state that violates a Clauser-Horne-Shimony-Holt inequality by more than four standard deviations, and …
Entanglement generation and protection by detuning modulation
2006
We introduce a protocol for steady-state entanglement generation and protection based on detuning modulation in the dissipative interaction between a two-qubit system and a bosonic mode. The protocol is a global-addressing scheme which only requires control over the system as a whole. We describe a postselection procedure to project the register state onto a subspace of maximally entangled states. We also outline how our proposal can be implemented in a circuit-quantum electrodynamics setup.
Continuous-Variable Instantaneous Quantum Computing is Hard to Sample
2017
Instantaneous quantum computing is a sub-universal quantum complexity class, whose circuits have proven to be hard to simulate classically in the Discrete-Variable (DV) realm. We extend this proof to the Continuous-Variable (CV) domain by using squeezed states and homodyne detection, and by exploring the properties of post-selected circuits. In order to treat post-selection in CVs we consider finitely-resolved homodyne detectors, corresponding to a realistic scheme based on discrete probability distributions of the measurement outcomes. The unavoidable errors stemming from the use of finitely squeezed states are suppressed through a qubit-into-oscillator GKP encoding of quantum information,…
All-optical long-distance quantum communication with Gottesman-Kitaev-Preskill qubits
2021
Quantum repeaters are a promising platform for realizing long-distance quantum communication and thus could form the backbone of a secure quantum internet, a scalable quantum network, or a distributed quantum computer. Repeater protocols that encode information in single- or multi-photon states are limited by transmission losses and the cost of implementing entangling gates or Bell measurements. In this work, we consider implementing a quantum repeater protocol using Gottesman-Kitaev-Preskill (GKP) qubits. These qubits are natural elements for quantum repeater protocols, because they allow for deterministic Gaussian entangling operations and Bell measurements, which can be implemented at ro…
Investigación en la escuela

Se persigue romper con los tratamientos puntuales e inconexos, haciendo posible una correcta comprensión de la situación y la participación en la adopción de medidas adecuadas. Andalucía Ma…
Rethinking Secular Time in Victorian England
2022
This open access book draws on conceptual resources ranging from medieval scholasticism to postmodern theory to propose a new understanding of secular time and its mediation in nineteenth-century technological networks. Untethering the concept of secularity from questions of ‘religion’ and ‘belief’, it offers an innovative rethinking of the history of secularisation that will appeal to students, scholars, and everyone interested in secularity, Victorian culture, the history of technology, and the temporalities of modernity.

Una revolución científica a la que Educación Química quiere contribuir
2014
AbstractSustainability Science aims to integrate the study of social development and natural processes to fa a new paradigm thatvour both of them and make possible the transition to Sustainability. This deep scientific revolution cannot be the result of just a new knowledge discipline: it must become a new paradigm that impregnates the ensemble of scientific disciplines and social activities.ResumenLa Ciencia de la Sostenibilidad tiene como objetivo integrar el estudio del desarrollo social y los procesos naturales para favorecer a ambos y posibilitar la transición hacia la sostenibilidad. Esta profunda revolución científica no puede ser el resultado de solo una nueva disciplina del conocim…
