Exploring the unification of quantum theory and general relativity with a Bose-Einstein condensate
Richard Howl, Roger Penrose, Ivette Fuentes
Despite almost a century's worth of study, it is still unclear how general relativity (GR) and quantum theory (QT) should be unified into a consistent theory. The conventional appr…
Designing quantum experiments with a genetic algorithm
Rosanna Nichols, Lana Mineh, Jesús Rubio +2
We introduce a genetic algorithm that designs quantum optics experiments for engineering quantum states with specific properties. Our algorithm is powerful and flexible, and can ea…
Dissipative entanglement preparation via Rydberg antiblockade and Lyapunov control
Zong-Xing Ding, Chang-Sheng Hu, Li-Tuo Shen +3
Preparation of entangled steady states via dissipation and pumping in Rydberg atoms has been recently found to be useful for quantum information processing. The driven-dissipative…
Assisted work distillation
Benjamin Morris, Ludovico Lami, Gerardo Adesso
We study the process of assisted work distillation. This scenario arises when two parties share a bipartite quantum state and their task is to locally distil the optimal a…
Evolution of confined quantum scalar fields in curved spacetime. Part I
Luis C. Barbado, Ana L. Báez-Camargo, Ivette Fuentes
We develop a method for computing the Bogoliubov transformation experienced by a confined quantum scalar field in a globally hyperbolic spacetime, due to the changes in the geometr…
Quantum-metrology estimation of spacetime parameters of the Earth outperforming classical precision
Jan Kohlrus, David Edward Bruschi, Ivette Fuentes
We consider quantum communication schemes where quantum optical signals are exchanged between a source on Earth and a satellite. The background curved spacetime affects the quantum…
