Fibre bundle formulation of nonrelativistic quantum mechanics. IV. Mixed states and evolution transport's curvature

open access: yes, 1999
We propose a new systematic fibre bundle formulation of nonrelativistic quantum mechanics. The new form of the theory is equivalent to the usual one but it is in harmony with the modern trends in theoretical physics and potentially admits new ...

Counterfactual Statements and Weak Measurements: an Experimental Proposal [PDF]

open access: yes, 2001
A recent analysis [quant-ph/0104062] suggests that weak measurements can be used to give observational meaning to counterfactual reasoning in quantum physics.

Efficient quantum processing of three–manifold topological invariants

open access: yes, 2009
A quantum algorithm for approximating efficiently three–manifold topological invariants in the framework of SU(2) Chern–Simons–Witten (CSW) topological quantum field theory at finite values of the coupling constant k is provided. The model of computation

Bell scenarios with communication

open access: yes, 2016
Classical and quantum physics provide fundamentally different predictions about experiments with separate observers that do not communicate, a phenomenon known as quantum nonlocality.

Quantum information and physics: Some future directions [PDF]

open access: yes, 1999
I consider some promising future directions for quantum information theory that could influence the development of 21st century physics. Advances in the theory of the distinguishability of superoperators may lead to new strategies for improving the ...

Fermionic Linear Optics Revisited

open access: yes, 2004
We provide an alternative view of the efficient classical simulatibility of fermionic linear optics in terms of Slater determinants. We investigate the generic effects of two-mode measurements on the Slater number of fermionic states.

Aqueous Colloidal Perovskite Quantum Emitters

open access: yesAdvanced Materials, EarlyView.
Facile structural transformation‐induced in situ core‐shell self‐assembly for constructing mono‐dispersed aqueous colloidal perovskite nanocrystals, exhibiting unprecedented aqueous solution single photon emission. Abstract Aqueous solutions of nanoparticles are the cornerstones for applications in diagnostics, catalysis and more, where control over ...

Total Syntheses of β‐ and γ‐Naphthocyclinones

open access: yesAngewandte Chemie, Volume 137, Issue 6, February 3, 2025.
The first total syntheses of β‐ and γ‐naphthocyclinones, the pyranonaphthoquinone dimers sharing unique dibenzobicyclo[3.2.1]octadienone skeleton, have been accomplished. The challenges are 1) stereoselective synthesis of the bicyclic skeleton and 2) enantio‐ and diasteoselective preparation of the pyranonaphthoquinone monomer.

Miscellaneous Applications of Quons [PDF]

open access: yes, 2007
This paper deals with quon algebras or deformed oscillator algebras, for which the deformation parameter is a root of unity. We show the interest of such algebras for fractional supersymmetric quantum mechanics, angular momentum theory and quantum ...

Breaking Bonds by Light: The Absorbance–Fragmentation Paradox

open access: yesChemistry – A European Journal, EarlyView.
Although octupolar and quadrupolar DMAQ‐derived probes showed superior ε and two‐photon absorption cross‐section (σ2) values relative to the dipolar one (1), the fragmentation efficiency exhibited inverse trend, and 1 emerged as the most effective caging group achieving Q = 12% quantum yield with σ2 = 86 GM and uncaging cross‐section δu = 10.2 GM at ...
