Quantum well states are quantized electronic states formed in thin films due to confinement of electron wave functions along surface normal direction by the surface and interface. First let us consider the textbook case: one dimensional square well problem in which a free electron is confined by th...
Quantum Well StatesFounded some 20 years ago,Glama Pak currently has two manufacturing sites located in Sydney and Melbourne,Australia.Employing some 80 people,the company manufactures lithographically printed corrugated boxes,folding cartons and point-of-sale display packaging.Their comprehensive production ...
Although the basic physics is similar, energy levels in atoms or molecules are generally not referred to as quantum well states. Artificial structures allow tailoring of properties, and metastable and nonequilibrium structures that are not found in nature due to thermodynamic requirements may offer ...
We show that Cs intercalated bilayer graphene acts as a substrate for the growth of a strained Cs film hosting quantum well states with high electronic quality. The Cs film grows in an fcc phase with a substantially reduced lattice constant of 4.9 Å corresponding to a compressive strain of ...

Only quantum systems like ions, electrons or superconducting circuits can exist in the superposition states that enable the power of quantum computing. A quantum particle such as an electron has its own “facing left or facing right” property, namely spin, referred to as either up or down, ...

These two quantum states are taken to correspond to the two states of a classical bit, namely0and1. The standard convention is to choose 0≡[10]1≡[01], although the opposite choice could equally well be taken. Thus, out of the infinite number of possible single-qubit quantum state vecto...
