“This could be a game-changing development, because 200 nanometres is far enough to allow inserting various control and readout devices in between the qubits, making the processor easier to wire up and operate.”
"What he had discovered, the engineers later realised, was a new way of manipulating the quantum state of a single qubit by using electric fields, rather than the magnetic fields they had been using previously"
“We show that the global field can be used to perform spin resonance of single electrons confined in a silicon double quantum dot device, establishing the feasibility of this approach for scalable spin qubit control.”
“Now a team of researchers at UNSW Sydney has broken new ground in proving that ‘spin qubits’ – properties of electrons representing the basic units of information in quantum computers – can hold information for up to two milliseconds. K”
