Quantum illumination reveals phase-shift inducing cloaking
(Nature Publishing, 2017-08-24)
In quantum illumination entangled light is employed to enhance the detection accuracy of an object when compared with the best classical protocol. On the other hand, cloaking is a stealth technology based on covering a ...
Supervised Quantum Learning without Measurements
(Nature Publishing, 2017-10-20)
We propose a quantum machine learning algorithm for efficiently solving a class of problems encoded in quantum controlled unitary operations. The central physical mechanism of the protocol is the iteration of a quantum ...
Approximate Quantum Adders With Genetic Algorithms: An IBM Quantum Experience
(De Gruyter Open, 2017-07)
It has been proven that quantum adders are
forbidden by the laws of quantum mechanics. We analyze
theoretical proposals for the implementation of approximate
quantum adders and optimize them by means
of genetic algorithms, ...
Degree of Quantumness in Quantum Synchronization
(Nature, 2019-12-27)
We introduce the concept of degree of quantumness in quantum synchronization, a measure of the quantum nature of synchronization in quantum systems. Following techniques from quantum information, we propose the number of ...
The TrapSensor Facility: an Open-Ring 7 Tesla Penning Trap for Laser-Based Precision Experiments
(IOP Publishing, 2019-02-28)
A Penning-trap facility for high-precision mass spectrometry based on a novel detection method has been built. This method consists in measuring motional frequencies of singly-charged ions trapped in strong magnetic fields ...
Parity-Assisted Generation of Nonclassical States of Light in Circuit Quantum Electrodynamics
(MDPI, 2019-03-13)
We propose a method to generate nonclassical states of light in multimode microwave cavities. Our approach considers two-photon processes that take place in a system composed of N extended cavities and an ultrastrongly ...
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 ...
