Periodic Reporting for period 1 - QUENML (Quantum-enhanced Machine Learning)
Reporting period: 2022-06-01 to 2023-05-31
Equal1's prototype spin silicon-based qubit chip devices currently operate at 4 Kelvin. The initial devices used charge qubits and have been recently updated to spin qubits which can deliver improved performance. Equal1's unique approach is to use commercial foundry processes to create our qubits. There are several disadvantages; however, the maturity of the commercial silicon ecosystem outweighs these disadvantages and promises a road map to systems that can accommodate the >1M qubits necessary to solve some of the world's most challenging problems.
Equal1 has developed three generations of prototype devices and, most recently, is focused on selecting the optimum design for our Spin-Qubits given the constraints we have imposed upon ourselves (single-chip, commercial foundry, low-power consumption, 4 Kelvin operation).
Currently, many competing technologies are striving to reach the goal of usable quantum computers that will achieve a quantum advantage over their classical counterparts. All technologies have various challenges, some unique and many overlapping. Equal1’s ‘System on Silicon’ approach brings additional challenges, and during the past year, we have focused on solving many of these issues.
This will ultimately enable the widespread adoption of an inclusive quantum computing ecosystem, empowering diverse users to harness its potential.
Equal1’s three generations of Quantum SoCs give us a wealth of experience upon which to build our next-generation devices. During the last 12mts, we have investigated several promising qubit designs and researched many more. In our next device, we will select the best combination of features compatible with our silicon partners' processes to maximize the performance of our qubits.
