Quantum Interferences In article number 2201024, Xiangfeng Shao, Colin J. Lambert, Hao-Li Zhang, and co-workers present the significant modulation effect of double N-substitution on quantum interference (QI) in meta-phenylene ethylene oligomer molecular devices, reveal how two N-atoms synergistically modulate conductance between destructive QI constructive states. The findings this work pave a ...

An improved « plug & play » interferometric system for quantum key distribution is presented. Self-alignment and compensation of birefringence remain, while limitations due to reflections are overcome. Original electronics implementing the BB84 protocol makes adjustment simple. Key creation with 0.1 photon per pulse at a rate of 325 Hz with a 2.9% QBER – corresponding to a net rate of 210Hz ove...

A quantum capacitance is calculated for a single wall carbon nan otube in a eld e ect device The calculation is performed on a base of a continuum model taking into account full microscopics A general ex pression for the atomistic capacitance of a nanotube of arbitrary shape is derived The result is useful for modeling of electromechanical action of a nanotube device and for nanotube electronic...

The generation of reversible circuits from high-level code is in important problem in several application domains, including low-power electronics and quantum computing. Existing tools compile and optimize reversible circuits for various metrics, such as the overall circuit size or the total amount of space required to implement a given function reversibly. However, little effort has been spent...

Silicene is an intriguing 2D topological material which is closely analogous to graphene but with stronger spin orbit coupling effect and natural compatibility with current silicon-based electronics industry. Here we demonstrate that silicene decorated with certain 3d transition metals (Vanadium) can sustain a stable quantum anomalous Hall effect using both analytical model and first-principles...

Control of electron spin coherence via external fields is fundamental in spintronics. Its implementation demands a host material that accommodates the desirable but contrasting requirements of spin robustness against relaxation mechanisms and sizeable coupling between spin and orbital motion of the carriers. Here, we focus on Ge, which is a prominent candidate for shuttling spin quantum bits in...
