Step towards quantum computer.


UNSW researchers 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.

“However, to be able to couple electron-spins on single atom qubits,  the qubits need to be placed with atomic precision, within just a few tens of nanometres of each other,”  she says.

“This poses a technical problem in how…
