The hyperlink representation of entanglement and the inclusion-exclusion principle

Silvia N. Santalla, Sudipto Singha Roy, Germán Sierra +1

The entanglement entropy (EE) of any bipartition of a pure state can be approximately expressed as a sum of entanglement links (ELs). In this work, we introduce their exact extensi…

Kicked-Ising Quantum Battery

Sebastián V. Romero, Xi Chen, Yue Ban

Entanglement has been identified as a key resource for enhancing charging performance in quantum batteries. We show that the kicked-Ising model at the self-dual point provides an e…

Making the Virtual Real: Measurement-Powered Tunneling Engines

Rafael Sánchez, Alok Nath Singh, Andrew N. Jordan +1

Quantum tunneling allows electrons to be transferred between two regions separated by an energetically forbidden barrier. Performing a position measurement that finds a particle in…

Constructing qubit edge states by inverse-designing the electromagnetic environment

A. Miguel-Torcal, T. F. Allard, P. A. Huidobro +2

Building on advances in topological photonics and computational optimization, we inversedesign a periodic dielectric structure surrounding a chain of interacting qubits, emulating…

Casimir-Lifshitz Theory for Cavity Modification of Ground-State Energy

Oleg V. Kotov, Johannes Feist, Francisco J. García-Vidal +1

A theory for ground-state modifications of matter embedded in a Fabry-Perot cavity and whose excitations are described as harmonic oscillators is presented. Based on Lifshitz's the…

Evolution of tripartite entanglement in three-qubit Quantum Gravity-Induced Entanglement of Masses (QGEM) with quantum decoherence

Pablo Guillermo Carmona Rufo, Anupam Mazumdar, Carlos Sabín

The recently introduced quantum gravity-induced entanglement of masses (QGEM) protocol aims to test the quantum nature of gravity by witnessing the entanglement produced by the vir…
