The spin degree of freedom of an electron or a nucleus is one of the most basic properties of
nature and functions as an excellent qubit, as it provides a natural two-level system that is …

Spintronics, or spin electronics, involves the study of active control and manipulation of spin
degrees of freedom in solid-state systems. This article reviews the current status of this …

For the first time in history, we are seeing a branching point in computing paradigms with the
emergence of quantum processing units (QPUs). Extracting the full potential of computation …

The entanglement of a pure state of a pair of quantum systems is defined as the entropy of
either member of the pair. The entanglement of formation of a mixed state ρ is the minimum …

We propose an implementation of a universal set of one-and two-quantum-bit gates for
quantum computation using the spin states of coupled single-electron quantum dots …

In recent years, stylized forms of the Boltzmann equation, now going by the name of" Lattice
Boltzmann equation"(LBE), have emerged, which relinquish most mathematical complexities …

In the light of the tremendous progress that has been made in raising the transition
temperature of the copper oxide superconductors (for a review, see ref.), it is natural to …

Artificial atoms like the nitrogen vacancy (NV) centers in diamond enable the realization of
fully functional qubits in a solid at room temperature. The functionalities of all the parts …
