Bounded Entanglement Entropy in the Quantum Ising Model
Autor: Petra F. Scudo, Tobias J. Osborne, Geoffrey Grimmett
Publikováno v: Journal of Statistical Physics 178 (2020), Nr. 1
Funder: University of Cambridge
A rigorous proof is presented of the boundedness of the entanglement entropy of a block of spins for the ground state of the one-dimensional quantum Ising model with sufficiently strong transverse field. This is p

One of the challenges for achieving efficient exciton transport in solar energy conversion systems is precise structural control of the light-harvesting building blocks. Here, we create a tunable material consisting of a connected chromophore network

Spectral converters and luminescent solar concentrators
Autor: Luciano Caccianotti, Roberto Fusco, Luigi Abbondanza, Petra F. Scudo
Publikováno v: Solar Energy Materials and Solar Cells. 94:1241-1246
In this paper we present a comprehensive theoretical description of molecular spectral converters in the specific context of luminescent solar concentrators (LSCs). The theoretical model is an extension to a three-level system interacting with a sola

CONVERGENCE OF COINED QUANTUM WALKS ON ℝd
Autor: Petra F. Scudo, Svante Janson, Alex D. Gottlieb
Publikováno v: Infinite Dimensional Analysis, Quantum Probability and Related Topics. :129-140
Coined quantum walks may be interpreted as the motion in position space of a quantum particle with a spin degree of freedom; the dynamics are determined by iterating a unitary transformation which is the product of a spin transformation and a transla

Low-cost approach for broadband enhancement of ultraviolet to visible light downconversion in fluorescent media
Autor: Iacopo Malfanti, Roberto Fusco, Matteo Burresi, Diederik S. Wiersma, Rajeshkumar Mupparapu, Kevin Vynck, Petra F. Scudo, Silvia Vignolini
Publikováno v: IEEE Photonics Conference 2012.
The addition of a tiny amount of Aluminum nanoparticles in dye solutions is shown to yield a significant enhancement of the down conversion of ultraviolet light while maintaining a high transparency at visible wavelengths.

Metallic nanoparticles are known to enhance nonlinear optical processes due to a local enhancement of the optical field. This strategy has been proposed to enhance downconversion in thin film solar cells, but has various disadvantages, among which is

Entanglement in the quantum Ising model
Autor: Tobias J. Osborne, Petra F. Scudo, Geoffrey Grimmett
We study the asymptotic scaling of the entanglement of a block of spins for the ground state of the one-dimensional quantum Ising model with transverse field. When the field is sufficiently strong, the entanglement grows at most logarithmically in th

Quantum estimation of relative information
Autor: Petra F. Scudo, Netanel H. Lindner, Dagmar Bruß
We derive optimal schemes for preparation and estimation of relational degrees of freedom between two quantum systems. We specifically analyze the case of rotation parameters representing relative angles between elements of the SU(2) symmetry group.

De Finetti representation theorem for quantum-process tomography
Autor: Petra F. Scudo, Rüdiger Schack, Christopher A. Fuchs
Publikováno v: Physical Review A. 69
In quantum process tomography, it is possible to express the experimenter's prior information as a sequence of quantum operations, i.e., trace-preserving completely positive maps. In analogy to de Finetti's concept of exchangeability for probability
