Tower: data structures in Quantum superposition

open access: yesProceedings of the ACM on Programming Languages, 2022
Emerging quantum algorithms for problems such as element distinctness, subset sum, and closest pair demonstrate computational advantages by relying on abstract data structures. Practically realizing such an algorithm as a program for a quantum computer requires an efficient implementation of the data structure whose operations correspond to unitary ...

Experimental demonstration of classical analogous time-dependent superposition of states

open access: yesScientific Reports, 2022
One of the quantum theory concepts on which quantum information processing stands is superposition. Here we provide experimental evidence for the existence of classical analogues to the coherent superposition of energy states, which is made possible by ...

On quantum phase crossovers in finite systems [PDF]

open access: yes, 2006
In this work we define a formal notion of a quantum phase crossover for certain Bethe ansatz solvable models. The approach we adopt exploits an exact mapping of the spectrum of a many-body integrable system, which admits an exact Bethe ansatz solution ...

Space-time dual quantum Zeno effect: Interferometric engineering of open quantum system dynamics

open access: yesPhysical Review Research, 2022
Superposition of trajectories, which modify quantum evolutions by superposing paths through interferometry, has been utilized to enhance various quantum communication tasks.

Implementable Hybrid Quantum Ant Colony Optimization Algorithm

open access: yes, 2021
We propose a new hybrid quantum algorithm based on the classical Ant Colony Optimization algorithm to produce approximate solutions for NP-hard problems, in particular optimization problems.

Student ability to distinguish between superposition states and mixed states in quantum mechanics

open access: yesPhysical Review Special Topics. Physics Education Research, 2015
Superposition gives rise to the probabilistic nature of quantum mechanics and is therefore one of the concepts at the heart of quantum mechanics. Although we have found that many students can successfully use the idea of superposition to calculate the ...

Insolubility from No-Signalling [PDF]

open access: yes, 2013
This paper improves on the result in my http://philsci-archive.pitt.edu/9121/, showing that within the framework of the unitary Schroedinger equation it is impossible to reproduce the phenomenological description of quantum mechanical measurements (in ...

Axion-like dark matter detection using Stern–Gerlach interferometer

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
Quantum sensors based on the superposition of neutral atoms are promising for sensing the nature of dark matter (DM). In this study, we utilize the Stern–Gerlach (SG) interferometer configuration to seek a novel method for the detection of axion-like ...
