Thermal baths as quantum resources: More friends than foes?
(IOP Publishing, 2015-11-06)
In this article we argue that thermal reservoirs (baths) are potentially useful resources in processes involving atoms interacting with quantized electromagnetic fields and their applications to quantum technologies. One ...
Quantum discord determines the interferometric power of quantum states
(American Physical Society - APSCollege Park, 2014)
Quantum metrology exploits quantum mechanical laws to improve the precision in estimating technologically relevant parameters such as phase, frequency, or magnetic fields. Probe states are usually tailored to the particular ...
Polarimetric Optical High-Voltage Sensor Using Synthetic-Heterodyne Demodulation and Hilbert Transform With Gain Control Feedback
(Ieee-inst Electrical Electronics Engineers Inc, 2017-03-01)
Optical voltage sensors are widely used for high-voltage (HV) sensing, but the measurement accuracy is often compromised by a sensitivity drift due to variations in the ambient conditions. Synthetic-heterodyne demodulation ...
Quantum charge pumping in graphene-based devices: when lattice defects do help
(American Institute of Physics, 2013-09)
Quantum charge pumping, the quantum coherent generation of a dc current at zero bias through time-dependent potentials, provides outstanding opportunities for metrology and the development of nanodevices. The long electronic ...
Entanglement-Enhanced Phase Estimation without Prior Phase Information
(American Physical Society, 2017-06)
We study the generation of planar quantum squeezed (PQS) states by quantum nondemolition (QND) measurement of an ensemble of Rb87 atoms with a Poisson distributed atom number. Precise calibration of the QND measurement ...

Manipulation of multimode squeezing in a coupled waveguide array
(American Physical Society, 2019)
© 2019 American Physical Society. ©2019 American Physical Society.We present a scheme for generating and manipulating three-mode squeezed states with genuine tripartite entanglement by injecting single-mode squeezed light ...
Quantum Manipulation of Nitrogen-Vacancy Centers in Diamond: From Basic Properties to Applications
(2010)
TThis thesis presents works not only to understand the spin degree of freedom
present in the nitrogen-vacancy defect in diamond: its internal structure and its relation
to its environment, but also to find novel applications ...
El efecto Hall cuántico y sus contextosThe quantum Hall effect and its contexts
(Universidade de São Paulo, 2013-01)
En este artículo, se atienden ciertas facetas conceptuales y experimentales del efecto Hall cuántico. Se argumenta que el mismo ofrece variados matices para la reflexión filosófica, desde la generación de entidades teóricas ...
