This PhD project at the University of Southampton, within the EPSRC Centre for Doctoral Training in Quantum Technology Engineering, focuses on developing a novel hardware platform for Quantum Reservoir Computing using Nano-Opto-Electro-Mechanical (NOEM) coupled quantum oscillators. The research aims to advance quantum neural networks, leveraging quantum information as data for machine learning algorithms. Candidates can pursue either a modelling approach, suitable for those with a Computer Science background, or a device fabrication route, ideal for Physics or Electronic Engineering students. The modelling path involves developing mathematical or numerical models of NOEM-based quantum reservoir computing, while the experimental route seeks to fabricate NOEM-coupled oscillators capable of operating in the quantum regime. The project offers substantial training in scientific, technical, and commercial skills, preparing students for careers in quantum technology. Funding is competitive, with UK students eligible for a 4-year UKRI TechExpert tax-free stipend of approximately £31,000 per year, and studentships at the UKRI base rate available for EU, Horizon Europe, and International students. Overseas applicants with external funding are also encouraged to apply. Entry requirements include an undergraduate degree with at least UK 2:1 honours or international equivalent, and applications must include a CV, two academic references, degree transcripts/certificates, and English language qualification if applicable. The university supports equality, diversity, and inclusivity, considers personal circumstances, and offers part-time study options. The application deadline is 31 July 2026, with an earlier deadline of 31 March 2026 for international applicants. For further information, candidates are encouraged to contact the supervisors, Dr Yoshishige Tsuchiya and Dr Srinandan Dasmahapatra.

This PhD project at the University of Southampton, within the EPSRC Centre for Doctoral Training in Quantum Technology Engineering, focuses on developing a novel nano-opto-electro-mechanical (NOEM) tunable silicon carbide (SiC) entangled photon source for future on-chip quantum photonic circuits. The research aims to establish a robust technological platform for generating entangled photon pairs in a controlled manner, advancing quantum information and communication technology. The project involves design optimisation, device fabrication, and single photon measurements to demonstrate the working principle and tunability of the device. Opto-electro-mechanical interactions will be used to control the timing of single photon emissions and regulate the level of entanglement from two adjacent photon sources. SiC is chosen as the platform material for its suitability in integrated, reconfigurable quantum circuits. The outcome will be a novel tunable entangled photon generator demonstrated on a silicon-based substrate, contributing to discrete photon generation device research and paving the way for on-chip photon-source-integrated quantum circuit technologies. The project is a collaboration between the University of Southampton and the Institute of Science Tokyo. Students will receive substantial training in scientific, technical, and commercial skills. UK students are eligible for a 4-year UKRI TechExpert tax-free stipend of around £31k per year, with studentships at the UKRI base rate available for EU, Horizon Europe, and International students. Overseas students with external funding are also encouraged to apply. Entry requirements include an undergraduate degree with at least a UK 2:1 honours or international equivalent.

This PhD project at the University of Southampton, within the EPSRC Centre for Doctoral Training in Quantum Technology Engineering, focuses on developing novel Micro/Nano-Electro-Mechanical Systems (MEMS/NEMS) switches to dramatically reduce the stand-by power consumption of integrated quantum circuits. The research aims to design and prototype RF/DC MEMS/NEMS switches optimized for low temperature operation, leveraging their ultralow off-state current due to mechanical separation—a significant advantage over conventional semiconductor switches like FETs. The project will utilize Southampton's cleanroom facilities for device fabrication and will investigate suitable contact materials for reliable low temperature performance. These optimized switches will be integrated into quantum circuits, such as those used in quantum computers and sensors, to evaluate and enhance overall energy efficiency. The project offers substantial training in scientific, technical, and commercial skills, and the supervisory team maintains strong collaborative links with research institutions in Japan and potential industry partners.
