Objective
Quantum dots (QDs), nanosystems so small that their size determines their properties, have revolutionised fields as diverse as light emission, photovoltaics, and biomedicine, primarily by exploiting their optical properties. QDs have, as well, extraordinary electrical properties that have placed them at the forefront of quantum information processing technologies, as hosts of semiconductor spin qubits. To operate, spins qubits necessitate deep cryogenic temperatures, and high frequency analog signals, typically delivered from room temperature. To advance towards scalable integrated quantum computing systems, cryogenic electronics are needed but the high power dissipated by these circuits have prevented tighter integration.
QuDos is the high-risk high-reward answer to this challenge, that bases its core programme on the hypothesis that the same embodiment for spin-qubit, QDs, could be utilized to demonstrate revolutionary new devices for cryogenic low-power analog applications. Particularly, QuDos will exploit, for the first time, the dissipationless high-frequency non-linear admittance of QDs, the quantum capacitance, to deliver stand-alone low-power analog circuits for the control and readout of solid-state quantum devices, as well as demonstrate that an integrated quantum-classical readout chain based on semiconductor QDs can be constructed.
The vision of QuDos sits on four main pillars: (i) Exploit the quantum capacitance of semiconductor QDs to demonstrate novel analog devices with superior performance to classical systems, (ii) Explore the fundamental physics of QDs at high frequency leading to new electronic device properties, (iii) Demonstrate an integrated low-power QD-based architecture for quantum state readout including qubits and the analog front end and (iv) Develop a simulation framework for hybrid QDs circuits at microwave frequencies. The research carried in QuDos will lay the foundation for a paradigm shift in information processing with QD tech.
