Emergence of string-like physics from Lorentz invariance in loop quantum gravity [PDF]

open access: yes, 2014
We consider a quantum field theory on a spherically symmetric quantum space time described by loop quantum gravity. The spin network description of space time in such a theory leads to equations for the quantum field that are discrete.

Post-quantum steering is a stronger-than-quantum resource for information processing

open access: yesnpj Quantum Information, 2022
We present the first instance where post-quantum steering is a stronger-than-quantum resource for information processing – remote state preparation.

The trouble with orbits: the Stark effect in the old and the new quantum theory [PDF]

open access: yes, 2014
The old quantum theory and Schr\"odinger's wave mechanics (and other forms of quantum mechanics) give the same results for the line splittings in the first-order Stark effect in hydrogen, the leading terms in the splitting of the spectral lines emitted ...

Bosonic fields in states with undefined particle numbers possess detectable non-contextuality features, plus more

open access: yesNew Journal of Physics, 2022
The paradoxical features of quantum theory are usually formulated for fixed number of particles. While one can now find a formulation of Bell’s theorem for quantum fields, a Kochen–Specker-type reasoning is usually formulated for just one particle, or ...

Proposal for demonstration of long-range cluster state entanglement in the presence of photon loss

open access: yesAPL Photonics, 2017
Photonic cluster states are a crucial resource for optical quantum computing. Recently a quantum dot single photon source has been demonstrated to produce strings of single photons in a small linear cluster state.

Causal Quantum Theory and the Collapse Locality Loophole

open access: yes, 2005
Causal quantum theory is an umbrella term for ordinary quantum theory modified by two hypotheses: state vector reduction is a well-defined process, and strict local causality applies. The first of these holds in some versions of Copenhagen quantum theory
