Scan Quantum Mechanics: Quantum Inertia Stops Superposition
Journal of Physics: Conference Series, 2016 A novel interpretation of the quantum mechanical superposition is put forward. Quantum systems scan all possible available states and switch randomly and very rapidly among them.

Quantum superposition inspired spiking neural network. [PDF]
iScience, 2021 Despite advances in artificial intelligence models, neural networks still cannot achieve human performance, partly due to differences in how information is encoded and processed compared to human brain. Information in an artificial neural network (ANN) is represented using a statistical method and processed as a fitting function, enabling handling of ...

Macroscopic Quantum Superposition in Cavity Optomechanics
Physical Review Letters, 2016 Quantum superposition in mechanical systems is not only key evidence for macroscopic quantum coherence, but can also be utilized in modern quantum technology. Here we propose an efficient approach for creating macroscopically distinct mechanical superposition states in a two-mode optomechanical system.

Probing macroscopic quantum superpositions with nanorotors [PDF]
New Journal of Physics, 2018 Whether quantum physics is universally valid is an open question with far-reaching implications. Intense research is therefore invested into testing the quantum superposition principle with ever heavier and more complex objects.

Stable Macroscopic Quantum Superpositions [PDF]
Physical Review Letters, 2011 We study the stability of superpositions of macroscopically distinct quantum states under decoherence. We introduce a class of quantum states with entanglement features similar to Greenberger-Horne-Zeilinger (GHZ) states, but with an inherent stability against noise and decoherence.

Completely scrambled memory for quantum superposition. [PDF]
Sci Rep, 2019 AbstractAlthough constructing a quantum computation device with multiple qubits is arguably a difficult task, several seconds of coherence time with tens of thousands of quantum particles has been demonstrated with a trapped atomic ensemble. As a practical application, a security-enhanced quantum state memory using atoms has been demonstrated.

Superpositional Quantum Network Topologies [PDF]
International Journal of Theoretical Physics, 2004 We introduce superposition-based quantum networks composed of (i) the classical perceptron model of multilayered, feedforward neural networks and (ii) the algebraic model of evolving reticular quantum structures as described in quantum gravity. The main feature of this model is moving from particular neural topologies to a quantum metastructure which ...

Superpositions in atomic quantum rings [PDF]
Physical Review A, 2013 Ultracold atoms are trapped circumferentially on a ring that is pierced at its center by a flux tube arising from a light-induced gauge potential due to applied Laguerre-Gaussian fields. We show that by using optical coherent state superpositions to produce light-induced gauge potentials, we can create a situation in which the trapped atoms are ...

Black holes decohere quantum superpositions
International Journal of Modern Physics D, 2022 We show that if a massive body is put in a quantum superposition of spatially separated states, the mere presence of a black hole in the vicinity of the body will eventually destroy the coherence of the superposition. This occurs because, in effect, the gravitational field of the body radiates soft gravitons into the black hole, allowing the black ...
