... The QA described above has been tested on our SQC by simulating the antiferromagnetic spin 1/2 Heisenberg model with J = −1 on triangular lattices of L = 6, 10, 15, 21 sites, subject to free boundary conditions. The ground-state properties of this model can be computed by standard sparse-matrix tech ...

Semiclassical Correlation in Density

Testing Wavefunction Collapse

It is possible that the Hamiltonian needed to generate the protective interaction depends on the wavefunction being measured which would imply that we must first know the wavefunction before we can measure it. This diffic ...

A Fresh View for Maxwell`s Equations and Electromagnetic Wave

Meanwhile, when the intensity of the electric field starts decreasing, the operators start creating particles. From the poi ...
