As a qubit processor developer, Archer, which has a market capitalisation of $67.53 million, has introduced the 12CQ chip to advance the quantum computing industry. In working with QMUL, Archer is improving the functionality of this project by using graphene to make electrical contact with the carbon nanosphere spin material.
Previously in the partnership, Archer and QMUL provided the building blocks for readout and control of the electron spins in a qubit by using Coulomb blockade to demonstrate the coupling of spins to superconduct resonator micro-devices.
Coulomb blockade is the inhibition of electron tunnelling, allowing Archer the precise control of a small number of electrons on a quantum dot.
The new program of work will aim to identify electron spin states in the electrical data from devices, allowing the spin state to be identified from the qubit at an estimated cost of $279,000 for the six-month extension.
By the end of the partnership, parties will be able to measure the spin relaxation on the single electron devices by using advanced pulsed gating.
CEO Simon Ruffell says that previous work with QMUL on the Coulomb blockade indicates crucial progress to the partnership.
“The work being done with QMUL bolsters the development of quantum devices and will ultimately lead to readout. Control and readout are the key milestones we must meet in advancing towards a qubit demonstration,” Ruffell says.
Archer Materials creates quantum technologies to evolve quantum computing and medical diagnostics, focusing on the semiconductor industry.
