Quantum Oblivion: A Master Key for Many Quantum Riddles

  title={Quantum Oblivion: A Master Key for Many Quantum Riddles},
  author={Avshalom C Elitzur and Eliahu Cohen},
  journal={arXiv: Quantum Physics},
A simple quantum interaction is analyzed, where the paths of two superposed particles asymmetrically cross, while a detector set to detect an interaction between them remains silent. Despite this negative result, the particles' states leave no doubt that a peculiar interaction has occurred: One particle's momentum changes while the other's remains unaffected, in apparent violation of momentum conservation. Revisiting the foundations of the quantum measurement process offers the resolution… 
The Weak Reality That Makes Quantum Phenomena More Natural: Novel Insights and Experiments
The Heisenberg ontology is shown to be conceptually advantageous compared to the Schrödinger picture, and several recent advances are reviewed, discussed their foundational significance and point out possible directions for future research.
Direct counterfactual communication via quantum Zeno effect
By using the quantum Zeno effect and a single-photon source, direct communication without carrier particle transmission is implemented successfully and the feasibility of direct counterfactual communication is experimentally demonstrated with the current technique.
Interaction-Free Effects Between Distant Atoms
A Gedanken experiment is presented where an excited and a ground-state atom are positioned such that, within the former’s half-life time, they exchange a photon with 50% probability, and the result is apparently precluding entanglement, which gives rise to the Quantum Zeno effect.
Entanglement: Quantum or Classical?
This work discusses some inequalities and bounds that are violated by quantum states thereby falsifying the existence of some of the classical hidden variables theories and discusses some exciting manifestations of entanglement, such as N00N states and the non-separable single particle states.
Unveiling the curtain of superposition: Recent gedanken and laboratory experiments
What is the true meaning of quantum superposition? Can a particle genuinely reside in several places simultaneously? These questions lie at the heart of this paper which presents an updated survey of
Some Notes on Counterfactuals in Quantum Mechanics
A weak value analysis of quantum oblivion is performed and some new avenues for further research are suggested that offer a realistic, simple and intuitively appealing explanation to the unique role of quantum non- Events as well as to the foundations of QM.
In Praise of Quantum Uncertainty
Ind determinism, or more precisely, locally consistent indeterminism, should be understood as the enabler of most quantum phenomena (and possibly all of them).
Voices of Silence, Novelties of Noise: Oblivion and Hesitation as Origins of Quantum Mysteries
Among the (in)famous differences between classical and quantum mechanics, quantum counterfactuals seem to be the most intriguing. At the same time, they seem to underlie many quantum oddities. In
Nonlocal Position Changes of a Photon Revealed by Quantum Routers
A Bell-like theorem applied to this experiment challenges any alternative interpretation that avoids disappearance-reappearance in favor of local hidden variables.

This work shows that, contrary to this intuition, universal quantum computation can be achieved without interaction among initially independent two-level quantum subsystems, and hence has practical applications to color imaging of ancient arts, upon which light is forbidden to shine.


The Retrocausal Nature of Quantum Measurement Revealed by Partial and Weak Measurements
Quantum measurement is sometimes more effective when its result is not definite. Partial measurement turns the initial superposition not into a certain state but to a greater probability for it,
Nonlocal effects of partial measurements and quantum erasure
Partial measurement turns the initial superposition not into a definite outcome but into a greater probability for it. The probability can approach 100%, yet the measurement can undergo complete
The Two-State Vector Formalism: An Updated Review
The two-state vector formalism of quantum mechanics is a time-symmetrized approach to standard quantum theory particularly helpful for the analysis of experiments performed on preand post-selected
Interaction‐free quantum measurements: A paradox?
In Heisenberg’s famous discussion of the measurement of a particle’s position using a microscope, the momentum transferred to the particle by the scattered photon makes the particle’s momentum
A Foundational Principle for Quantum Mechanics
In contrast to the theories of relativity, quantum mechanics is not yet based on a generally accepted conceptual foundation. It is proposed here that the missing principle may be identified through
Are all quantum measurements reducible to local position measurements
A typical quantum measurement process involves two steps. Step one is to separate the initial wavefunction into its spatial components which are then guided towards detectors at different locations.
Quantitative conditional quantum erasure in two-atom resonance fluorescence
We present a conditional quantum eraser that erases the a priori knowledge or the predictability of the path a photon takes in a Young-type double-slit experiment with two fluorescent four-level
Delayed "Choice" quantum eraser
The experimental results demonstrate the possibility of delayed determination of particlelike or wavelike behavior via quantum entanglement, and the which-path or both-path information of a quantum can be marked or erased by its entangled twin even after the registration of the quantum.
Experimental demonstration of nonlocal effects in the partial-collapse measurement and reversal process
We demonstrate experimentally the nonlocal reversal of a partial-collapse quantum measurement of a two-photon entangled state. Both the partial-collapse measurement and the reversal operation are
