These so called "metamaterials" consist of very tiny objects with micrometer-scale dimensions.
Metallic quantum point contacts exhibit striking features, e.g., their atomic-scale dimension and electronic quantum transport, which have motivated extensive experimental and theoretical research in recent years1,2,3,4,5.
Loads of things operate on a quantum scale – including things you came up with, like photosynthesis!
"A grander vision is to have electronic circuits which are at the quantum scale," Dr. Forrest said.
Nano-structures traditionally provide approximate realizations of low-dimensional systems through confined electron states in one dimension (thin films, interfaces or quantum wells), two dimensions (quantum wires or nano-wires), or three dimensions (quantum dots or color centers).
We still have to scale the dimensions farther down".
And this quantum bullshit dimension contains all the tiny machinery that decides how everything works.
I will summarize the development and performance of atomic ion trap systems at both university and industrial settings, including demonstrations of quantum algorithms and simulations that show a path to scaling quantum computers to useful dimensions, and also a high-level software layer that allows autonomy and remote use via a cloud service.
Quantum networks scale the advantages of quantum key distribution protocols to more than two distant users.
For global-scale quantum communications, quantum repeaters [8] and quantum satellites [9 11] are potential solutions.
As critical transistor dimensions scale below the 100 nm (nanoscale) regime, quantum mechanical (QM) effects begin to manifest themselves and affect important device performance metrics.
