Fault tolerant silicon-based quantum processors - Industrial Track Doctoral Studentship

UCL’s CDT in Delivering Quantum Technologies is pleased to announce an Industrial Track Studentship on fault tolerant silicon-based quantum processor with industrial partner Quantum Motion.

Silicon-based approaches to quantum information processors offer advantages such as high qubit density, record qubit coherence lifetimes for the solid state, and the ability to leverage the advanced nanofabrication methods of CMOS technologies. This project will focus on the measurement of silicon quantum devices, including spin qubits based on donor atoms and/or quantum dots, measuring basic qubit properties, as well as single- and multi- qubit gate fidelities, to help validate and refine fault-tolerant architectures based on spin qubits in silicon. The project will also develop robust and scalable ways to read out and manipulate spin qubits. Collaborations with the project will include theoretical groups on the design of fault-tolerant quantum architectures in silicon as well as nano-fabrication facilities. There will be opportunities to learn about advanced nanofabrication techniques as well as to develop experience of quantum transport, reflectometry, coherent control and measurements an milliKelvin temperatures in a dilution refrigerator.

Past work
The spins of donor atoms in silicon have record quantum coherence lifetimes for solid-state systems, being up to seconds for the electron spin [1] and hours for the nuclear spin [2]. Spins of single quantum dots and donors can be manipulated and controlled with high fidelity [3], and indeed both can be coupled together in CMOS-compatible silicon nanodevices [4]. Stimulated by this great promise, a variety of promising architectures are being developed to enable scaling to larger numbers of spins [5,6].
Quantum Motion is a recent start-up founded by Professor Simon Benjamin (University of Oxford) and Professor John Morton (UCL), developing new technology aimed at creating a quantum computer based on silicon.
