Quantum Permutations and Beyond Quantum Controlled Reference Frames
Ofek Bengyat, Časlav Brukner, Marios Christodoulou
Quantum permutations, or magic unitaries, have in recent years been explored in the context of identifying `genuinely quantum' isometries of graphs. Here, we import this tool in ph…
Complete Relational Description of Spin in a Quantum Background
Hannah Troger, Ofek Bengyat, Thomas D. Galley +1
The standard description of the state of a spin in quantum mechanics presupposes externally fixed directions -- a classical background. Can a spin be fully described instead in rel…
Gravity Mediated Entanglement between Oscillators as Quantum Superposition of Geometries
Ofek Bengyat, Andrea Di Biagio, Markus Aspelmeyer +1
Protocols for observing gravity induced entanglement typically comprise the interaction of two particles prepared either in a superposition of two discrete paths, or in a continuou…
Characterization of Supernovae Based on the Spectral-Temporal Energy Distribution: Possible two SN Ib Subtypes
Ofek Bengyat, Avishay Gal-Yam
A quantitative data-driven comparison among supernovae (SNe) based on their spectral time series combined with multi-band photometry is presented. We use an unsupervised Random For…
