This is a research and Innovation Action of the Eu Horizon 2020 Programme
In this project, CMOS technology will be exploited to fabricate nanodevices to implement and benchmark different architectures of quantum bits (qubits) based on spin degree of freedom at cryogenic temperatures. The goal of the project is the identification of the most suitable physical qubit architecture in terms of scalability and to fabricate the first CMOS-based qubit in a reliable manner to pave the way to the development of a solid-state quantum computer.
In particular, five different spin qubit architectures will be investigated: quantum dot (QD)-based singlet-triplet qubits, QD-donor hybrid qubit, QD hybrid qubit, QD single spin qubit and donor spin qubits. For each architecture two qubits devices will also be investigated. Solutions about driving, readout and coupling of the qubit states as well as a detailed design of physical qubits will be provided to exploit the scalability of CMOS technology. Efficient qubit control will be assured by optmized low temperature electonics. Finally, a proposal of a scalable fault tolerant logical qubit obtained with the most suitable physical qubit will be given.
