Improving quantum gate fidelities using optimized Euler angles
K. Ch. Chatzisavvas, G. Chadzitaskos, C. Daskaloyannis +1
An explicit algorithm for calculating the optimized Euler angles for both qubit state transfer and gate engineering given two arbitary fixed Hamiltonians is presented. It is shown…
Quantum Computation Beyond the "Standard Circuit Model"
K. Ch. Chatzisavvas, C. Daskaloyannis, C. P. Panos
Construction of explicit quantum circuits follows the notion of the "standard circuit model" introduced in the solid and profound analysis of elementary gates providing quantum com…
Quantum machine language and quantum computation with Josephson junctions
K. Ch. Chatzisavvas, C. Daskaloyannis, C. P. Panos
An implementation method of a gate in a quantum computer is studied in terms of a finite number of steps evolving in time according to a finite number of basic Hamiltonians, which…
Quantum Algebraic Symmetries in Nuclei, Molecules and Atomic Clusters
Dennis Bonatsos, C. Daskaloyannis
Various applications of quantum algebraic techniques in nuclear structure physics and in molecular physics are briefly reviewed and a recent application of these techniques to the…
Coupled Q-oscillators as a model for vibrations of polyatomic molecules
Dennis Bonatsos, C. Daskaloyannis, P. Kolokotronis
The system of two -deformed oscillators coupled so that the total Hamiltonian has the su(2) symmetry is proved to be equivalent, to lowest order approximation, to a system o…
