Quantum networks require quantum nodes that are built using quantum dots.
However, a new study impressively solves these challenges. The study authors successfully used 13,000 nuclear spins in a gallium arsenide (GaAs) quantum dot system to create a scalable quantum register.
Quantum networks require quantum nodes that are built using quantum dots — tiny particles, much smaller than a human hair, which can trap and control electrons, and store quantum information.
Quantum dots are valued for their ability to emit single photons because single-photon sources are key requirements for secure quantum communication and quantum computing applications.
