Stability Thresholds for Gravitationally Induced Entanglement in Shielded Setups
Jan Bulling, Marit O. E. Steiner, Julen S. Pedernales +1
Proposed experiments for gravitationally induced entanglement (GIE) typically suppress direct electromagnetic interactions between two massive particles by inserting a conducting F…
Optically Hyperpolarized Materials for Levitated Optomechanics
Marit O. E. Steiner, Julen S. Pedernales, Martin B. Plenio
We explore the potential of levitating solids embedded with non-permanent, optically controllable electron spins, which can be used to hyperpolarize their nuclear spin environment…
On the origin of force sensitivity in tests of quantum gravity with delocalised mechanical systems
Julen S. Pedernales, Martin B. Plenio
The detection of the quantum nature of gravity in the low-energy limit hinges on achieving an unprecedented degree of force sensitivity with mechanical systems. Against this backgr…
Testing the quantum nature of gravity without entanglement
Ludovico Lami, Julen S. Pedernales, Martin B. Plenio
Given a unitary evolution on a multi-partite quantum system and an ensemble of initial states, how well can be simulated by local operations and classical communication (LO…
Ground-State Cooling of Levitated Magnets in Low-Frequency Traps
Kirill Streltsov, Julen S. Pedernales, Martin B. Plenio
We present a ground-state cooling scheme for the mechanical degrees of freedom of mesoscopic magnetic particles levitated in low-frequency traps. Our method makes use of a binary s…
Enhanced force sensitivity and entanglement in periodically driven optomechanics
F. Cosco, J. S. Pedernales, M. B. Plenio
Squeezing is a resource that enables precision enhancements in quantum metrology and can be used as a basis for the generation of entanglement by linear optics. While strong squeez…
