A nanocrystal's cross-section for stimulated emission is regularly hidden in ultrafast transient absorption spectra owing to overlapping excited-state absorption and ground-state bleaching. In a recent study, a novel three-pulse femtosecond...

Quantum sensing utilizes the exquisite sensitivity of quantum states to external field (magnetic, electric, thermal and electromagnetic) to detect and measure physical quantities of interest with unprecedented sensitivity and accuracy. Here...
Signatures of coherent energy transfer and exciton delocalization in time-resolved optical cross correlations [0.03%]

We investigate how optical second-order cross correlations witness the quantum features of a prototype donor-acceptor light-harvesting unit. By considering a pair of detuned two-level emitters electronically coupled and incoherently driven ...

The field of molecular excitons and related supramolecular systems has largely focused on aggregates where nearest neighbour couplings dominate. We propose that radically different states can be produced by moving beyond that paradigm. In p...

In recent work, the author has developed a general category-theoretic framework for decision theory. This article applies this to the category of orthomodular lattices (OMLs). Every Boolean algebra is an OML, so this yields a new (syntactic...

Combinatorial problems pose significant challenges, especially for large-scale instances. A promising approach to addressing these challenges involves quadratic unconstrained binary optimization (QUBO) models, a key framework in quantum com...
A hybrid column generation-based heuristic for solving the parallel machine scheduling problem with sequence-dependent set-up times [0.03%]

This study explores the application of a hybrid quantum-classical algorithm for solving the parallel machine scheduling problem (PMSP) with sequence-dependent set-up times, a pivotal scheduling problem that has applications in multiple indu...
Limitations of quantum counting, nested quantum search and amplitude amplification and their potential to solve discrete optimization problems [0.03%]

Several quantum algorithms have been proposed for solving discrete optimization problems. In this paper, we focus on the quantum counting algorithm (QCB) of Brassard G, Høyer P, Tapp A. 1998 Quantum counting. In Automata, languages and pro...

Quantum randomness evidently transcends the classical framework of random variables defined on a single comprehensive Kolmogorov probability space. One prominent example is the quantum double-slit experiment owing to Feynman (Feynman 1951 I...

In a series of recent scientific contributions, the role of bosonic and fermionic ladder operators in a macroscopic realm has been investigated. Creation, annihilation and number operators have been used in very different contexts, all shar...
