Investigating and controlling the quantum resources of bipartite-qubit detectors of scalar fields in the process of spacetime expansion

European Physical Journal C: Particles and Fields, 2023
Quantum resources construct new avenues to explore the cosmos. Considering bipartite-qubit detectors subjected to scalar fields in an expanding spacetime, quantum resources (including quantum coherence, quantum discord, Bell-nonlocality, and nonlocal ...

Interpreting the Modal Kochen-Specker Theorem: Possibility and Many Worlds in Quantum Mechanics [PDF]

, 2013
In this paper we attempt to physically interpret the Modal Kochen-Specker (MKS) theorem. In order to do so, we analyze the features of the possible properties about quantum systems arising from the elements in an orthomodular lattice and distinguish the ...

Plasmon‐Enhanced Second‐Harmonic Generation in Atomically Thin Crystalline Silver Nanostructures

Advanced Materials, EarlyView.
Atomically thin crystalline silver films combine vertical quantum confinement with lateral plasmonic field enhancement to boost second‐harmonic generation. Nanoribbon and nanotriangle arrays enable geometry‐tunable infrared plasmon resonances, producing strong SHG from deeply subwavelength metallic volumes compatible with silicon‐based nanophotonics ...

Nonlocality, violation of lorentz in variance, and wave-particle duality in quantum theory [PDF]

, 1992
This thesis addresses some of the consequences of giving quantum mechanics a realist interpretation. We consider three main topics: wave-particle duality, locality, and Lorentz invariance.

Intuitionistic quantum logic of an n-level system [PDF]

, 2009
A decade ago, Isham and Butterfield proposed a topos theoretic approach to quantum mechanics, which meanwhile has been extended by Doering and Isham so as to provide a new mathematical foundation for all of physics.

Lithium Niobate Electro‐Optic Photonic Processor for Variational Quantum Eigensolver

Advanced Science, EarlyView.
An integrated lithium‐niobate‐on‐insulator ququart processor implements an electro‐optically controlled photonic variational quantum eigensolver using single photons encoded in four path modes. Bell‐basis‐emulating ququart projective measurements reduce measurement settings while achieving chemical‐accuracy‐level molecular‐energy estimation.

Exposure of subtle multipartite quantum nonlocality

npj Quantum Information, 2021
The celebrated Einstein–Podolsky–Rosen quantum steering has a complex structure in the multipartite scenario. We show that a naively defined criterion for multipartite steering allows, like in Bell nonlocality, for a contradictory effect whereby local ...

Time-symmetry without retrocausality: how the quantum can withhold the solace [PDF]

, 2010
It has been suggested that some of the puzzles of QM are resolved if we allow that there is retrocausality in the quantum world. In particular, it has been claimed that this approach offers a path to a Lorentz-invariant explanation of Bell correlations ...

Sharing nonlocality between sequential observers by means of projective measurements [PDF]

, 2022
openWeak measurements are considered fundamental for sharing the nonlocality of an entangled two-qubit state between several sequential observers. In this thesis work, we show that this is not necessarily true.
