Coherent states in the quantum multiverse [PDF]
Phys.Lett.B683:1-6,2010, 2009 In this paper, we study the role of coherent states in the realm of quantum cosmology, both in a second-quantized single universe and in a third-quantized quantum multiverse. In particular, most emphasis will be paid to the quantum description of multiverses made up of accelerated universes.

Retroduction, Multiverse Hypotheses and Their Testability [PDF]
arXiv, 2006 The actual existence of collections of universes -- multiverses -- is strongly suggested by leading approaches to quantum cosmology, and has been proposed earlier as an attractive way to explain the apparent fine-tuned character of our universe. But, how can such hypotheses be tested?

Probabilities in the inflationary multiverse [PDF]
Journal of Cosmology and Astroparticle Physics, 2006 18 pages, RevTeX 4, 2 figures. Discussion of the full probability in Sec.VI is sharpened; the conclusions are strengthened. Note added explaining the relation to recent work by Easther, Lim and Martin.

Thoughts on Defining the Multiverse [PDF]
arXiv, 2008 The possibility that the multiverse corresponds to physical reality deserves serious investigation. Having three different important theories,(quantum mechanics, string theory and inflation), predict the existence of the multiverse is hardly coincidental.

Hybrid quantum investment optimization with minimal holding period
Scientific Reports, 2021 In this paper we propose a hybrid quantum-classical algorithm for dynamic portfolio optimization with minimal holding period. Our algorithm is based on sampling the near-optimal portfolios at each trading step using a quantum processor, and efficiently ...

Variational quantum non-orthogonal optimization
Scientific Reports, 2023 Current universal quantum computers have a limited number of noisy qubits. Because of this, it is difficult to use them to solve large-scale complex optimization problems.

Variational quantum and quantum-inspired clustering
Scientific Reports, 2023 Here we present a quantum algorithm for clustering data based on a variational quantum circuit. The algorithm allows to classify data into many clusters, and can easily be implemented in few-qubit Noisy Intermediate-Scale Quantum devices. The idea of the
