A generic qubit unitary operator affected by quantum noise is duplicated and inserted in a coherently superposed channel, superposing two paths offered to probe across the noisy unitary, driven control qubit. characterization performed of transformation realized channel on joint state probe-control pair. The then specifically analyzed for fundamental metrological task phase estimation with perf...
We introduce a two-parameter approximate counter-diabatic term into the Hamiltonian of transverse-field Ising model for quantum annealing to accelerate convergence solution, generalizing an existing single-parameter approach. The protocol is equivalent unconventional diabatic control longitudinal and transverse fields in thus makes it more feasible experimental realization than introduction new...
The collapse of antiferromagnetic order as a function of some quantum tuning parameter such as carrier density or hydrostatic pressure is often accompanied by a region of superconductivity. The corresponding phenomenon in the potentially simpler case of itinerant-electron ferromagnetism, however, remains more illusive. In this paper we consider the reasons why this may be so and summaries evi...
In this paper, the quantum chemistry calculations related to the structural parameter of the chromite and molybdate anions and the complexes obtained from them with the glycine and alanine amino acids were performed. The calculations were carried out using HF and DFT methods and in the base series 6-31G *. Thermodynamic studies related to the formation of complexes have been considered and thei...
Introduction: Proton therapy delivers radiation to tumor tissue in a much more confined way than conventional photon therapy thus allowing the radiation oncologist to use a greater dose while still minimizing side. Materials and Methods: protons release most of their energy within the tumor region. As a result, the treating physician can potentially give an...
