Starting with the simplest semiclassical approaches and ending with the description of
complex fully quantum-mechanical methods for quantum transport analysis of state-of-the …

The control of electrons at the level of the elementary charge e was demonstrated
experimentally already in the 1980s. Ever since, the production of an electrical current ef, or …

Wiring Up Silicon Surfaces One of the challenges in downsizing electronic circuits is
maintaining low resistivity of wires, because shrinking their diameter to near atomic …

Quantum computers hold the promise of massive performance enhancements across a
range of applications, from cryptography and databases to revolutionary scientific simulation …

Practical quantum computers require a large network of highly coherent qubits,
