Engineering negative stress-energy densities with quantum energy teleportation

Abstract

We use quantum energy teleportation in the light-matter interaction as an operational means to create quantum field states that violate energy conditions and have negative local stress-energy densities. We show that the protocol is optimal in the sense that it scales in a way that saturates the quantum interest conjecture.

Continuous-variable quantum teleportation with vacuum-entangled Rindler modes

“…It is also a natural setting to analyse continuous-variable protocols where only discrete-variable versions have been studied, and these can be straightforwardly mapped to quantum optical contexts. An immediate extension to this work would be to implement other entanglement-based protocols using the quantum circuit model, such as continuousvariable dense coding [32,33], quantum energy teleportation [34][35][36][37][38] and quantum key distribution [15]. As before, we add these terms together and integrate over ω, γ to obtain the photon number variance.…”

“…Eq. ( 34)- (37) imply that the complete sets of right-moving modes in Regions I and III and the leftmoving modes in Regions II and IV are entangled, in the same way that space-like separated Rindler modes in (R) and (L) and time-like separated conformal modes in (F) and (P) are entangled. In the following analysis, we harness this entanglement as the resource for teleportation between the accelerated and stationary observers.…”

The geometry of spacetime from quantum measurements

“…These tools have been successfully employed in the study of plenty of phenomena in quantum field theory, such as the Unruh effect [4][5][6][7][8] and Hawking radiation [9,10]. Nowadays, many protocols of relativistic quantum information have been developed through the use of particle detector models, such as entanglement harvesting [11][12][13][14][15][16][17][18][19][20], quantum and classical communication [21][22][23][24][25][26][27][28] and quantum energy teleportation [29][30][31][32] to cite some. Moreover, particle detector models have a natural connection with experimental setups, being able model the interaction of atoms with light [33][34][35][36] and nucleons with neutrinos [37,38] in more accurate ways than the typical models employed in quantum optics (e.g.…”

Is Temperature Quenching in the Early Universe Due to Particle Production, Or Quantum Occupation States, Or the Influence of Quantum Teleportation?

“…The author also thanks another friend who wishes to be unnamed for making him aware of reference [22] as to the astounding implications of negative energy states, as a result of quantum teleportation. This is a venue on a Pre Planckian to Planckian regime of space-time in conjunction with the change in energy as brought up in Equation (18) with a presumed initial negative energy states, as far as teleportation, which may be a link between a prior to a present universe, and also account for the sheer magnitude of the temperatures which may ensue.…”

“…Corda's treatment of if scalar-tensor gravity is indicated here, or General relativity is decisively important. Secondly, the magnitude of Planckian space-time to positive energy states, by the mechanism discussed in [22], with the magnitude of this energy switch given by Equation (18), i.e. the audacity of the idea of this energy shift, as given in Equation (18) could be in fact set by a switch from initial low negative energy values to positive energy at the Planckian boundary.…”
