Introduction To Green Computing And Its Importance
2020/7/23· In conventional computers we work with now, computing and processing of data is based on transistors’ on and off states as binary representation of ‘1’ or ‘0,’ or vice versa. In quantum computers, the basic principle is to use quantum properties to represent data.
Coherent control of single spins in silicon carbide
In short: Electron spins that can be prepared in arbitrary states are the basic elements for quantum spintronics, such as quantum computing and nanoscale sensing. Here we demonstrate that missing atoms in a silicon carbide crystal can host single spins that are accessible by optical spectroscopy, with long coherence times even at room temperature.
