Archer Materials improves quantum detection methods

Quantum development company Archer Materials has announced improvements in how the company detects single electron spins in a quantum computing device.

Quantum computers store and retrieve information at the sub atomic level, utilising different spin states of an atom’s orbiting electrons.

The Archer quantum team, led by Dr Simon Ruffell and Dr Byron Villis, has developed a new method using resonators that can be adjusted to how they respond to a spin signal.

This means Archer can now finetune the resonators to make its readings faster and more accurate, according to a company update to investors.

Adjustable resonator responses allow the Company to handle more quantum bits (qubits of information) at once.

Archer also announced a project with Queen Mary University of London (QMUL) to study important phenomena in quantum physics.

The Executive Chair of Archer Greg English said: “Our quantum team…has achieved a lot during the past few months, and we look forward to updating the market on the results of our work with QMUL.

“Archer’s research is ongoing as it aims to enhance its devices and progress toward practical quantum computing applications.”

According to Archer’s statement, the team conducted measurements over three separate test sessions.

Each session refined the detection circuits, studying the characteristics of single electron box devices in different settings.

“As a result, Archer can more effectively read the quantum states of the materials used in these devices.”

Archer’s project with Queen Mary University of London will study electron movement using graphene-based nanodevices, to observe the Coulomb blockade phenomenon, an important phenomenon in quantum physics.
