Senior Quantum Engineer - Parametric Circuits

About The Role and Team As a Senior Quantum Engineer, you will play a critical role in the development and execution of experiments focused on silicon-based quantum computing systems. This is a rare and exciting opportunity to be an employee at a scale-up shaping the future of quantum computing. You would be part of the Quantum Hardware Team that specializes in designing, validating and operating quantum processors based on silicon industrial technology. More particularly, as part of the ERC CoG project QuDos, you would focus on developing ultra-low-power microwave qubit control and readout electronics for quantum computers. Our Team 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, and we have recently closed our Series C funding of $160 million. 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 in the UK (Oxford and London), Australia (Sydney) and Spain (San Sebastián). We are proud to expand our operations in San Sebastián, Spain in the new CIC nanoGUNE Quantum Tower. This expansion is part of the European Research Council - Consolidator Grant, QuDos, awarded to Prof. M. Fernando Gonzalez-Zalba to develop low-power quantum electronics devices based on semiconductor nanostructures. Functions of the Role • Design and demonstrate ultra-low power devices for qubit control and readout based on non-linear reactive elements such as the quantum capacitance of silicon quantum dots and the kinetic inductance of thin-film superconductors. • Perform combined demonstration of the aforementioned devices with silicon qubit structures. Experience - Essentials • A PhD degree in physics or engineering • Proven record of experience in the development of quantum-limited amplification (e.g. JPAs, TWPAs) • Experience with high-frequency electronic simulation software (e.g. Keysight ADS, Ansys HFSS, CST Microwave Studio). • Familiar with the use of high-frequency electronics: AWGs, MW signal generators, IQ (de)modulators • Ability to independently design and carry out complex experiments; perform data analysis and preparation of technical reports and presentations • Knowledge of data acquisition software (Python) • Ability to work in a team • Excellent verbal and written communication skills Experience - Desirable • Experience with the use of deep cryogenic measurement systems • Experience with the dynamical characterisation silicon-based nanoelectronic devices • Knowledge of quantum information systems and operations • Ability to supervise research students Benefits • Be part of a creative, world-leading team • Competitive salary • Flexible working hours • Choice of laptop EEO Statement Quantum Motion is committed to providing equal employment opportunity and does not discriminate based on age, sex, sexual orientation, gender identity, race, color, religion, disability status, marital status, pregnancy, gender reassignment, or any other protected characteristics covered by Spanish employment law.
