Since 2021 our team has been listed every year in the “Top 100 Startups worth watching” in the EE Times, and our technology breakthroughs have been featured in The Telegraph, BBC and the New Statesman. Our founders are internationally renowned researchers from UCL and Oxford University who have pioneered the development of qubits and quantum computing architectures. Our chairman is the co-founder of Cadence and Synopsys, the two leading companies in the area of Electronic Design Automation. We’re backed by a team of top-tier investors including Bosch Ventures, Porsche SE, Sony Innovation Fund, Oxford Sciences Innovations, INKEF Capital and Octopus Ventures, and we have so far raised over £62 million in equity and grant funding. 

We bring together the brightest quantum engineers, integrated circuit (IC) engineers, quantum computing theoreticians and software engineers to create a unique, world-leading team, working together closely to maximise our combined expertise. Our collaborative and interdisciplinary culture is an ideal fit for anyone who thrives in a cutting-edge research and development environment focused on tackling big challenges and contributing to the development of scalable quantum computers based on silicon technology

Our team of 100+ is based across London, Oxford, Spain and Sydney, with our primary hub in Islington (London) and our Sydney lab based in Redfern.

The Quantum Hardware Team at Quantum Motion specialises in designing, validating and operating quantum processors based on silicon (CMOS) industrial technology. This PhD track is experimental in nature with laboratory based work. Silicon-based approaches to quantum computing 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. Two-qubit gate fidelities for spin qubits in silicon now exceed 99.5% and registers of up to 6 qubits have been made so far. By integrating CMOS quantum devices on-chip with ‘classical’ digital and analogue electronics, arrays of up to 1024 quantum dots have been addressed and rapidly characterised in just 5 minutes. These advances open up many exciting research opportunities for spin-qubits based on silicon MOS (metal-oxide-semiconductor) devices, fabricated using the same processes used routinely across the IC industry today.  

This PhD project, part of the CSIRO Next Generation Quantum Graduates Scholarship Program, is an exciting collaboration between academia and industry with the industrial placement at Quantum Motion.

Project Focus 
The transition from small-scale demonstrations to useful, scaled quantum computers requires rigorous measurement and characterization. This PhD track is experimental in nature with laboratory-based work, offering the chance to work at the cutting edge of quantum engineering. Your work will be central to understanding and verifying the performance of our next-generation hardware. 

This PhD topic will cover the design and measurement of silicon spin qubits based on quantum dots (QDs). Silicon-based approaches are key to scalability, offering high qubit density, record qubit coherence lifetimes for the solid state, and the ability to leverage the advanced nanofabrication methods of CMOS technologies.

The primary focus will be on developing and implementing system and qubit benchmark techniques that are useful for near-term and longer-term spin qubit processors. The student will work towards establishing and demonstrating useful metrics and reliable means of characterising increasingly complex qubit device architectures.

You will gain hands-on experience and deep expertise in:

• Advanced nanofabrication techniques.

• Fast readout and coherent control of qubits.

• All experimental work is performed at millikelvin temperatures in dilution refrigerators.

• Minimum First Class honours degree in the fields of Physics or Electrical Engineering or closely related discipline studied to master’s level

• Particular experience of relevance will depend on the direction the student would like to take in the PhD project – understanding and/or experience in at least one of the following topics would be beneficial: quantum computing, measuring quantum devices, cryogenic measurements, analogue circuit design, machine learning, microwave engineering

• Experience of working in a laboratory environment

• Demonstrated ability to perform experiments, data analysis and preparation of technical reports and presentations                 

• Knowledge of scripted data acquisition software, such as Python or Matlab                                               

• Excellent communication skills and demonstrated experience of working collaboratively in a team environment

This project would suit an exceptional electrical engineering, quantum engineering, or physics student with a strong foundation in quantum mechanics and data analysis. The ideal candidate will be adept at devising and applying practical engineering solutions to the challenges of scaling tomorrow's quantum computers.
