Quantum Computing relies on very low temperature electronics, independent of selected quantum technology. SEQUENCE aims at providing a new paradigm by developing and implementing high performance cryogenic electronics to enable wide use of quantum computing.
SEQUENCE will make use of Unconventional Nanoelectronics to develop cryogenic electronics and demonstrate their usability and effectiveness for quantum computing systems.
- Objective 1 – 3D Electronics: To introduce 3D integration at cryogenic conditions to combine technologies, including qubit layers, and reduce form factors, latency, and power consumption enabling qubit multiplexing strategies to significantly reduce the number of physical components inside and outside the cryostat.
- Objective 2 – Cryogenic Electronics: To develop a new generation low-power cryogenic electronics, with LNAs, multiplexers, RF switches, DACs and oscillators combining III-V and Si CMOS technologies, for scalable quantum computers.
- Objective 3 – Cryogenic Transistors: To develop and validate cryogenic transistor and circuit models to reduce the design margins of cryogenic circuits operating at extremely low power levels leveraging unique low-temperature effects, such as reduced subthreshold slopes, carrier scattering and carrier interaction with defect states.
- Objective 4 – Nanoelectronics Devices:To develop and benchmark novel nanoelectronic device concepts with added values (functionality and performance) at cryogenic temperatures.
- Objective 5 – Develop Synergies: To leverage the developed cryogenic and 3D technology platforms towards space and terrestrial communication. As a result of the SEQUENCE project, synergies provided by the co-development between the abovementioned fields and quantum computing will be found and developed.
