Experimental motivation and empirical consistency in minimal no-collapse quantum mechanics
Maximilian Schlosshauer
We analyze three important experimental domains (SQUIDs, molecular interferometry, and Bose-Einstein condensation) as well as quantum-biophysical studies of the neuronal apparatus…
Noncommuting Observables and Local Realism
James D. Malley, Arthur Fine
A standard approach in the foundations of quantum mechanics studies local realism and hidden variables models exclusively in terms of violations of Bell-like inequalities. Thus qua…
From optimal measurement to efficient quantum algorithms for the hidden subgroup problem over semidirect product groups
Dave Bacon, Andrew M. Childs, Wim van Dam
We approach the hidden subgroup problem by performing the so-called pretty good measurement on hidden subgroup states. For various groups that can be expressed as the semidirect pr…
Self-induced decoherence approach: Strong limitations on its validity in a simple spin bath model and on its general physical relevance
Maximilian Schlosshauer
The "self-induced decoherence" (SID) approach suggests that (1) the expectation value of any observable becomes diagonal in the eigenstates of the total Hamiltonian for systems end…
Renormalization of the singular attractive potential
Mary Alberg, Michel Bawin, Fabian Brau
We study the radial Schrödinger equation for a particle of mass in the field of a singular attractive potential with particular emphasis on the bound states problem…
Efficient Quantum Circuits for Schur and Clebsch-Gordan Transforms
Dave Bacon, Isaac Chuang, Aram Harrow
The Schur basis on n d-dimensional quantum systems is a generalization of the total angular momentum basis that is useful for exploiting symmetry under permutations or collective u…
