Quantum information recast via multiresolution in
Mandana Bidarvand, Artur Sowa
We present a multiresolution approach to the theory of quantum information. It arose from an effort to develop a systematic mathematical approach to the analysis of an infinite arr…
Solving the Bose-Hubbard model in new ways
A. P. Sowa, J. Fransson
We introduce a new method for analysing the Bose-Hubbard model for an array of bosons with nearest neighbor interactions. It is based on a number-theoretic implementation of the cr…
Entangling continuous variables with a qubit array
Patrick Navez, Artur Sowa, Alexander Zagoskin
We show that an array of qubits embedded in a waveguide can emit entangled pairs of microwave photon beams. The quadratures obtained from a homodyne detection of these outputs beam…
An almost-solvable model of complex network dynamics
Qi Guo, Artur Sowa
We discuss a specific model, which we refer to as RandLOE, of a large multi-agent network whose dynamic is prescribed via a combination of deterministic local laws and random exoge…
An exactly solvable quantum-metamaterial type model
A. P. Sowa, A. M. Zagoskin
The key difficulty in the modelling of large quantum coherent structures lies in keeping track of nonlocal, multipoint quantum correlations between their constituent parts. Here we…
Encoding spatial data into quantum observables
Artur Sowa
The focus of this work is a correspondence between the Hilbert space operators on one hand, and doubly periodic generalized functions on the other. The linear map that implements i…
