Quantum estimation of the Schwarzschild spacetime parameters of the Earth (2014)
Journal Article
Bruschi, D. E., Datta, A., Ursin, R., Ralph, T. C., & Fuentes, I. (2014). Quantum estimation of the Schwarzschild spacetime parameters of the Earth. Physical Review D, 90(12), doi:10.1103/PhysRevD.90.124001

We propose a quantum experiment to measure with high precision the Schwarzschild spacetime parameters of the Earth. The scheme can also be applied to measure distances by taking into account the curvature of the Earth’s spacetime. As a wave packet of...

Impurities as a quantum thermometer for a Bose-Einstein condensate (2014)
Journal Article
Sabín, C., White, A., Hackermuller, L., & Fuentes, I. (2014). Impurities as a quantum thermometer for a Bose-Einstein condensate. Scientific Reports, 4, 1-6. https://doi.org/10.1038/srep06436

We introduce a primary thermometer which measures the temperature of a Bose-Einstein Condensate in the sub-nK regime. We show, using quantum Fisher information, that the precision of our technique improves the state-of-the-art in thermometry in the s...

Spacetime effects on satellite-based quantum communications (2014)
Journal Article
Bruschi, D. E., Ralph, T. C., Fuentes, I., Jennewein, T., & Razavi, M. (2014). Spacetime effects on satellite-based quantum communications. Physical Review D - Particles, Fields, Gravitation and Cosmology, 90(4), doi:10.1103/physrevd.90.045041

Phonon creation by gravitational waves (2014)
Journal Article
Sabín, C., Bruschi, D. E., Ahmadi, M., & Fuentes, I. (2014). Phonon creation by gravitational waves. New Journal of Physics, 16, 1-15. https://doi.org/10.1088/1367-2630/16/8/085003

We show that gravitational waves create phonons in a Bose–Einstein condensate (BEC). A traveling spacetime distortion produces particle creation resonances that correspond to the dynamical Casimir effect in a BEC phononic field contained in a cavity-...

Gravitational parameter estimation in a waveguide (2014)
Journal Article

Relativistic Quantum Metrology: Exploiting relativity to improve quantum measurement technologies (2014)
Journal Article
Ahmadi, M., Bruschi, D. E., Sabín, C., Adesso, G., & Fuentes, I. (2014). Relativistic Quantum Metrology: Exploiting relativity to improve quantum measurement technologies. Scientific Reports, 4(1), 1-6. https://doi.org/10.1038/srep04996

We present a framework for relativistic quantum metrology that is useful for both Earth-based and space-based technologies. Quantum metrology has been so far successfully applied to design precision instruments such as clocks and sensors which outper...

Testing the effects of gravity and motion on quantum entanglement in space-based experiments (2014)
Journal Article
Bruschi, D. E., Sabín, C., White, A., Baccetti, V., Oi, D. K., & Fuentes, I. (2014). Testing the effects of gravity and motion on quantum entanglement in space-based experiments. New Journal of Physics, 16, 1-15. https://doi.org/10.1088/1367-2630/16/5/053041

We propose an experiment to test the effects of gravity and acceleration on quantum entanglement in space-based setups. We show that the entanglement between excitations of two Bose–Einstein condensates is degraded after one of them undergoes a chang...

Quantum metrology for relativistic quantum fields (2014)
Journal Article
Ahmadi, M., Fuentes, I., & Edward Bruschi, D. (2014). Quantum metrology for relativistic quantum fields. Physical Review D - Particles, Fields, Gravitation and Cosmology, 89(6), doi:10.1103/PhysRevD.89.065028

In quantum metrology quantum properties such as squeezing and entanglement are exploited in the design of a new generation of clocks, sensors and other measurement devices that can outperform their classical counterparts. Applications of great techno... Read More about Quantum metrology for relativistic quantum fields.
