Extraction of timelike entanglement from the quantum vacuum

S. Jay Olson, Timothy C. Ralph

Recently, it has been shown that the massless quantum vacuum state contains entanglement between timelike separated regions of spacetime, in addition to the entanglement between th…

Simulating quantum effects of cosmological expansion using a static ion trap

Nicolas C. Menicucci, S. Jay Olson, Gerard J. Milburn

We propose a new experimental testbed that uses ions in the collective ground state of a static trap for studying the analog of quantum-field effects in cosmological spacetimes, in…

Entanglement between the future and past in the quantum vacuum

S. Jay Olson, Timothy C. Ralph

We note that massless fields within the future and past light cone may be quantized as independent systems. We show that the vacuum is an entangled state of these systems, exactly…

Probability, unitarity, and realism in generally covariant quantum information

S. Jay Olson, Jonathan P. Dowling

The formalism of covariant quantum theory, introduced by Reisenberger and Rovelli, casts the description of quantum states and evolution into a framework compatable with the princi…

Generating Entangled Photons from the Vacuum by Accelerated Measurements: Quantum Information Theory Meets the Unruh-Davies Effect

Muxin Han, S. Jay Olson, Jonathan P. Dowling

Building on the well-known Unruh-Davies effect, we examine the effects of projective measurements and quantum communications between accelerated and stationary observers. We find t…

Information and measurement in generally covariant quantum theory

S. Jay Olson, Jonathan P. Dowling

Due to the absence of an external, classical time variable, the probabilistic predictions of covariant quantum theory are ambiguous when multiple measurements are considered. Here,…
