A position exists for a Research Assistant/Associate in Multiplexed Quantum Circuits. The candidate will work as part of an EPSRC Grant team entitled "Multiplexed Quantum Integrated Circuits" headed by Professor Charles G. Smith, who is a member of the Semiconductor Physics Group.

The aim of the role holder is to perform research using a dedicated BlueFors dilution refrigerator to investigate quantum properties of nano-devices using a low temperature multiplexer device developed within the group:


The applicant will be required to fabricate nano-structure semiconductor devices in our clean room and then measure these devices at cryogenic temperatures.  The role will be to extend the multiplexer to read out at higher frequencies.  The project will explore ways of applying the multiplexer to a number of nano-electronic devices including quantum technology applications.

The successful candidate will hold (or be close to obtaining) a PhD in physics, electrical engineering or a closely related discipline with a proven track record in quantum transport measurements in nano-structured devices at cryogenic temperatures, a strong background in nano-device fabrication and radio frequency measurements with the ability to pursue scientific investigation from the conceptions stage through to publication.

Preference will be given to candidates with experience in low temperature device measurements, optical or e-beam lithography and radio frequency measurements.

The candidate will also be expected to have proven organisational, communication and team working skills. We welcome a diverse range of applicants with skills closely related to those described above.

Salary Range: Research Assistant (Grade 5) £26,715 to £30,942. Research Associate (Grade 7) £32,816 to £40,322.
