Exploring Quantum Annealing Architectures: A Spin Glass Perspective

2024-03-27T14:34:55+01:00Tags: |

Authors: Jauma, Gabriel; Garcia-Ripoll, Juan Jose; Pino, Manuel Journal: ADVANCED QUANTUM TECHNOLOGIES Publication date: 2024/03/14 DOI: 10.1002/qute.202300245 Abstract: This work analyzes the spin-glass transition across various Ising models relevant to quantum annealers. By employing the parallel tempering method, the location of the spin-glass phase transition is extrapolated from the pseudo-critical temperature of finite-sized systems. The [...]

Directional spontaneous emission in photonic crystal slabs

2024-03-27T14:34:49+01:00Tags: , , |

Authors: Navarro-Baron, Erik P.; Vinck-Posada, Herbert; Gonzalez-Tudela, Alejandro Journal: NANOPHOTONICS Publication date: 2024/02/25 DOI: 10.1515/nanoph-2023-0843 Abstract: Spontaneous emission is one of the most fundamental out-of-equilibrium processes in which an excited quantum emitter relaxes to the ground state due to quantum fluctuations. In this process, a photon is emitted that can interact with other nearby emitters [...]
