Researchers at the University of New South Wales have proposed a new way to distinguish between quantum bits that are placed only a few nanometres apart in a silicon chip, taking them a step closer to the construction of a large-scale quantum computer.
Quantum bits, or qubits, are the basic building blocks of quantum computers -- ultra-powerful devices that will offer enormous advantages for solving complex problems.
Professor Michelle Simmons, leader of the research team, said a qubit based on the spin of an individual electron bound to a phosphorus atom within a silicon chip is one of the most promising systems for building a practical quantum computer, due to silicon's widespread use in the microelectronics industry.
