Scalable quantum memory in the ultrastrong coupling regime
(Nature Publishing, 2015-03-02)
Circuit quantum electrodynamics, consisting of superconducting artificial atoms coupled to on-chip resonators, represents a prime candidate to implement the scalable quantum computing architecture because of the presence ...
Digital Quantum Simulation of Spin Models with Circuit Quantum Electrodynamics
(American Physical Society, 2015-06-17)
Systems of interacting quantum spins show a rich spectrum of quantum phases and display interesting many-body dynamics. Computing characteristics of even small systems on conventional computers poses significant challenges. ...
Quantum Emulation of Gravitational Waves
(Nature Publishing Group, 2015-07-14)
Gravitational waves, as predicted by Einstein's general relativity theory, appear as ripples in the fabric of spacetime traveling at the speed of light. We prove that the propagation of small amplitude gravitational waves ...
Quantum Simulation of Dissipative Processes without Reservoir Engineering
(Nature Publishing Group, 2015-05-29)
We present a quantum algorithm to simulate general finite dimensional Lindblad master equations without the requirement of engineering the system-environment interactions. The proposed method is able to simulate both ...
Quantum Simulator for Transport Phenomena in Fluid Flows
(Nature Publishing Group, 2015-08-17)
Transport phenomena still stand as one of the most challenging problems in computational physics. By exploiting the analogies between Dirac and lattice Boltzmann equations, we develop a quantum simulator based on ...
Parity-dependent State Engineering and Tomography in the ultrastrong coupling regime
(Nature Publishing Group, 2015-07-08)
Reaching the strong coupling regime of light-matter interaction has led to an impressive development in fundamental quantum physics and applications to quantum information processing. Latests advances in different quantum ...
Low Effort L-i Nuclear Fusion Plasma Control Using Model Predictive Control Laws
(Hindawi Publishing, 2015)
One of the main problems of fusion energy is to achieve longer pulse duration by avoiding the premature reaction decay due to plasma instabilities. The control of the plasma inductance arises as an essential tool for the ...
Pretreatment with Resveratrol Prevents Neuronal Injury and Cognitive Deficits Induced by Perinatal Hypoxia-Ischemia in Rats
(Public Library Science, 2015-11-06)
Despite advances in neonatal care, hypoxic-ischemic brain injury is still a serious clinical problem, which is responsible for many cases of perinatal mortality, cerebral palsy, motor impairment and cognitive deficits. ...
Efficacy of a cognitive and behavioural psychotherapy applied by primary care psychologists in patients with mixed anxiety-depressive disorder: a research protocol
(Biomed Central, 2015-03-20)
Background: In contrast with the recommendations of clinical practice guidelines, the most common treatment for anxiety and depressive disorders in primary care is pharmacological. The aim of this study is to assess the ...
Fitting BICEP2 with defects, primordial gravitational waves and dust
(IOP Publishing, 2015)
In this work we discuss the possibility of cosmic defects being responsible for the B-mode signal measured by the BICEP2 collaboration. We also allow for the presence of other cosmological sources of B-modes such as ...
