Quantum Nanoscience

Quantum nanoscience is that the basic research area at the intersection of nanoscale science and quantum science that makes the understanding that permits development of nanotechnologies. With the growing work toward realization of quantum computing, quantum has taken on new meaning that describes the consequences at this scale. Quantum nanoscience explores and utilizes coherent quantum effects in engineered nanostructures. This property is vital when one intends to use the system for specific tasks, like performing a sequence of logic operations during a quantum computer. Quantum coherence is fragile and may easily be lost if the system becomes overlarge or is subjected to uncontrolled interactions with the environment. Quantum coherence-enabled functionality holds the promise of creating possible disruptive technologies like quantum computing, quantum communication, quantum simulation, and quantum sensing. This may eventually cause the planning of latest sorts of nanodevices and nanoscopic scale materials, where functionality and structure of quantum nanodevices are described through quantum phenomena such as superposition and entanglement. Current quantum refers to the quantum mechanical phenomena of superposition, entanglement and quantum coherence that are engineered rather than naturally-occurring phenomena. It uses quantum physics to explore and utilize coherent quantum effects in engineered nanostructures. Coherence is that the property of a quantum system that permits to predict its evolution in time, once it's been prepared during a superposition of various quantum states.
