Nonlocal Quantum Information Transfer Without Superluminal Signalling and Communication

  title={Nonlocal Quantum Information Transfer Without Superluminal Signalling and Communication},
  author={Jan Walleczek and Gerhard Gr{\"o}ssing},

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
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
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
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.

This Editorial introduces a Special Issue featuring contributions which were invited as part of the David Bohm Centennial symposium of the EmQM conference series and provides topical overviews of thirty-one contributions which are organized into seven categories to provide orientation.
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.
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
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
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.


The Non-Signalling theorem in generalizations of Bell's theorem
Does "epistemic non-signalling" ensure the peaceful coexistence of special relativity and quantum nonlocality? The possibility of an affirmative answer is of great importance to deterministic

The Einstein-Podolsky-Rosen correlations are very like many ordinary occurrences of everyday life. So it is a little difficult for the man in the street to understand immediately why there has been
Bell Nonlocality, Signal Locality and Unpredictability (or What Bohr Could Have Told Einstein at Solvay Had He Known About Bell Experiments)
The 1964 theorem of John Bell shows that no model that reproduces the predictions of quantum mechanics can simultaneously satisfy the assumptions of locality and determinism. On the other hand, the
Einstein, Incompleteness, and the Epistemic View of Quantum States
It is shown that for models wherein the quantum state has the status of something real, the failure of locality can be established through an argument considerably more straightforward than Bell’s theorem.

Quantum Entanglement is the essence of quantum physics and inspires fundamental questions about the principles of nature. Moreover it is also the basis for emerging technologies of quantum
No extension of quantum theory can have improved predictive power
This work says that no extension of quantum theory can give more information about the outcomes of future measurements than quantum theory itself, under the assumption that measurements can be chosen freely.

Non-local setting and outcome information for violation of Bell's inequality
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.
On the Einstein-Podolsky-Rosen paradox
THE paradox of Einstein, Podolsky and Rosen [1] was advanced as an argument that quantum mechanics could not be a complete theory but should be supplemented by additional variables. These additional

Recently it has been claimed that no extension of quantum theory can have improved predictive power, the statement following, according to the authors, from the assumptions of free will and of the
