Creating Faster, Stronger, and More Energy-Efficient Quantum Computers

UNSW scientists are moving further towards the goal of creating faster, stronger, and more energy-efficient computers. A new joint paper between FLEET (Australian Research Council’s Center for Excellence in Future Low Energy Electronic Technology) and CQC2T (ARC Center of Excellence for Quantum Computation and Communication Technology) and the University of British Columbia (Vancouver, Canada) say that the trade-off between operational speed and information consistency can be optimized through holes. Is shown. Mini quantum computer.

One way to create a qubit is to use the “spin” of an electron. It can be either up or down. To make quantum computers as fast and powerful as possible, FLEET scientists use only electric fields to operate quantum computers. It is applied using normal electrodes.

“Our theoretical research shows that we reach a solution by using holes that can be thought of as lack of electrons, behaving like positively charged electrons,” said UNSW Physics School. Dimi Culturer, an associate professor at the school, said. In this way, qubits can be robust to charge fluctuations due to solid background.

In addition, the “sweet spot” where qubits are the least sensitive to such noise is also the point at which qubits can operate fastest. “Our research predicts that such points are present in every qubit made of holes and provides a set of guidelines for reaching these points in the laboratory,” Dimi said. say.
