Quantum development company Archer Materials has announced improvements in how the company detects the spins of individual electrons in a quantum computing device.
Quantum computers store and retrieve information at the subatomic level, using different spin states of an atom’s orbiting electrons.
Archer’s quantum team, led by Dr Simon Ruffell and Dr Byron Villis, has developed a new method using resonators that can be tuned based on their response to a spin signal.
This means Archer can now fine-tune the resonators to make its readings faster and more accurate, according to a company update to investors.
The resonators’ tunable 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.
Archer Executive Chairman Greg English said: “Our quantum team… has accomplished a great deal over the past few months, and we look forward to updating the market on the results of our work with QMUL.
“Archer’s research continues with the aim of improving its devices and moving towards practical applications of quantum computing.”
According to Archer’s statement, the team conducted measurements during three separate testing sessions.
Each session allowed to refine the detection circuits, studying the characteristics of single-electron box devices in different contexts.
“Archer can thus more efficiently read the quantum states of the materials used in these devices.”
Archer’s project with Queen Mary University of London will study the movement of electrons using graphene-based nanodevices to observe the phenomenon of Coulomb blockade, an important phenomenon in quantum physics.
