# Nonlocal Quantum Information Transfer Without Superluminal Signalling and Communication

@article{Walleczek2016NonlocalQI, title={Nonlocal Quantum Information Transfer Without Superluminal Signalling and Communication}, author={Jan Walleczek and Gerhard Gr{\"o}ssing}, journal={Foundations of Physics}, year={2016}, volume={46}, pages={1208-1228} }

It is a frequent assumption that—via superluminal information transfers—superluminal signals capable of enabling communication are necessarily exchanged in any quantum theory that posits hidden superluminal influences. However, does the presence of hidden superluminal influences automatically imply superluminal signalling and communication? The non-signalling theorem mediates the apparent conflict between quantum mechanics and the theory of special relativity. However, as a ‘no-go’ theorem…

Conditions for Lorentz-invariant superluminal information transfer without signaling

- Physics
- 2016

It is shown that a basic argument discussing the allegedly paradox time ordering of events in EPR-type two-particle experiments falls short of taking into account the contextuality of the experimental setup, and under which circumstances superluminal information transfer (but not signaling) may be compatible with a Lorentz-invariant theory.

Based on quantum entanglement and corresponding quantum communication, we research a simple superluminal entangled communication scheme, whose key is to establish two mutually entangled particles or…

Agent Inaccessibility as a Fundamental Principle in Quantum Mechanics: Objective Unpredictability and Formal Uncomputability

- PhilosophyEntropy

The present work considers a third option—‘objective ignorance’: an in-principle limit for ontological quantum mechanics based upon self-referential dynamics, including undecidable dynamics and dynamical chaos, employing uncomputability as a formal limit.

Contextuality Revisited: Signaling May Differ From Communicating

- Computer ScienceSynthese Library

It is argued that it is important to distinguish two types of signaling: (1) signaling that Alice and Bob can use to communicate, and (2) signalingthat Alice andBob cannot use to communication.

The super-indeterminism in orthodox quantum mechanics does not implicate the reality of experimenter free will

The concept of 'super-indeterminism' captures the notion that the free choice assumption of orthodox quantum mechanics necessitates only the following requirement: an agent's free-choice performance…

Genuine Randomness vis-a-vis Nonlocality: Hardy and Hardy type Relations.

- Computer Science
- 2020

A combined study of maximum achievable as well as guaranteed amounts of GR, obtained for both fixed and varying preparation procedures, demonstrate that the nature of quantitative relationship between randomness and nonlocality is crucially dependent on which aspect (guaranteed/maximum amount) of GR is considered.

Vacuum Landscaping: Cause of Nonlocal Influences without Signaling

- PhysicsEntropy

It is shown with the examples of double- and n-slit interference that the assumed nonlocality of the distribution functions alone suffices to derive the de Broglie–Bohm guiding equation for N particles with otherwise purely classical means.

A Loss Resilient Entanglement Swapping Protocol using Non-Classical States of Light

- Physics, Computer Science
- 2018

This thesis presents two possible entanglement swapping protocols, and shows that these protocols are resilient to small levels of photonic losses, and proposes the use of these protocols in quantum communication schemes that require shared entangled qubits, in the form of a Bell state.

It is shown that it is impossible to model a violation without having information in one laboratory about both the setting and the outcome at the distant one, and the assumed experimenter's freedom to choose the settings ensures that the setting information must be non-locally transferred even when the SI condition is obeyed.
