From no causal loop to absoluteness of cause: discarding the quantum NOT logic

  title={From no causal loop to absoluteness of cause: discarding the quantum NOT logic},
  author={Anandamay Das Bhowmik and Preeti Parashar and Guruprasad Kar and Manik Banik},
The principle of ‘absoluteness of cause’ (AC) assumes the cause-effect relation to be observer independent and is a stronger assertion than just prohibiting occurrence of any causal loop. Here, we study implication of this stronger principle to derive a fundamental no-go result in quantum world. AC principle restrains the ‘time order’ of two spacelike separated events to be a potential cause of another event in their common future, and in turn negates existence of a quantum device that… Expand

The relativistic causality versus no-signaling paradigm for multi-party correlations
It is shown that, in the multipartite setting, the no-signalling condition is in general stronger than demanding relativistic causality in multi-party correlations, i.e., the rule that correlations do not allow casual loops. Expand
Bell measurement ruling out supraquantum correlations
The so called bipartite non-signaling boxes are systems whose statistics is constrained solely by the principle of no instantaneous signaling between distant locations. Such systems can exhibit muchExpand

The transition from classical to quantum mechanics rests on the recognition that the structure of information is not what we thought it was: there are operational, i.e., phenomenal, probabilisticExpand
Experimental realization of the quantum universal NOT gate
The experimental realization of a universal quantum machine that performs the best possible approximation to the universal NOT transformation is reported, an optical parametric amplifier of entangled photon states, which also enabled us to investigate universal quantum cloning. Expand
Information processing in generalized probabilistic theories
A framework in which a variety of probabilistic theories can be defined, including classical and quantum theories, and many others, is introduced, and a tensor product rule for combining separate systems can be derived. Expand
No-flipping as a consequence of no-signalling and non-increase of entanglement under LOCC
Abstract Non-existence of universal flipper for arbitrary quantum states is a fundamental constraint on the allowed operations performed on physical systems. The largest set of qubits that can beExpand
Can Quantum-Mechanical Description of Physical Reality Be Considered Complete?
Consideration of the problem of making predictions concerning a system on the basis of measurements made on another system that had previously interacted with it leads to the result that one is led to conclude that the description of reality as given by a wave function is not complete. Expand
Limited Holism and Real-Vector-Space Quantum Theory
This paper considers in this paper a class of theories more holistic than quantum theory in that they are constrained only by “bilocal tomography”: the state of any composite system is determined by the statistics of measurements on pairs of components. Expand
Impossibility of deleting an unknown quantum state
The linearity of quantum theory does not allow us to delete a copy of an arbitrary quantum state perfectly, and this could in principle be useful in quantum computation, where one could store new information in an already computed state by deleting the old information. Expand
No-signaling condition and quantum dynamics.
It is shown that the basic dynamical rules of quantum physics can be derived from its static properties and the condition that superluminal communication is forbidden, and this result constrains possible nonlinear modifications of quantum science. Expand
