Digital Quantum Rabi and Dicke Models in Superconducting Circuits
(Nature Publishing Group, 2014-12-15)
We propose the analog-digital quantum simulation of the quantum Rabi and Dicke models using circuit quantum electrodynamics (QED). We find that all physical regimes, in particular those which are impossible to realize in ...
The Forbidden Quantum Adder
(Nature Publishing Group, 2015-07-08)
Quantum information provides fundamentally different computational resources than classical information. We prove that there is no unitary protocol able to add unknown quantum states belonging to different Hilbert spaces. ...
Biomimetic Cloning of Quantum Observables
(Nature Publishing Group, 2014-05-09)
We propose a bio-inspired sequential quantum protocol for the cloning and preservation of the statistics associated to quantum observables of a given system. It combines the cloning of a set of commuting observables, ...
Advanced-Retarded Differential Equations in Quantum Photonic Systems
(Nature Publishing Group, 2017-02-23)
We propose the realization of photonic circuits whose dynamics is governed by advanced-retarded differential equations. Beyond their mathematical interest, these photonic configurations enable the implementation of quantum ...
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 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 ...
Artificial Life in Quantum Technologies
(Nature Publishing, 2016-02-08)
We develop a quantum information protocol that models the biological behaviours of individuals living in a natural selection scenario. The artificially engineered evolution of the quantum living units shows the fundamental ...
From transistor to trapped-ion computers for quantum chemistry
(Nature Publishing Group, 2014-01)
Over the last few decades, quantum chemistry has progressed through the development of computational methods based on modern digital computers. However, these methods can hardly fulfill the exponentially-growing resource ...
