QUES2T

QUES2T provides businesses and researchers access to advanced commercial quantum measurement and fabrication facilities.

At QUES2T businesses and researchers have access to the key infrastructure for the manufacture of high-quality solid-state quantum devices, including thin-film growth and advanced patterning. 

Business and researchers can have access to equipment for micro/nano-fabrication, thin-film growth and low-temperature measurement test-beds. 

QUES2T focuses on three of the most promising solid-state QT platforms to date:

1. Superconducting circuits: the foundation for the most complex solid-state quantum circuits achieved so far (e.g. Google, IBM, Rigetti, D-wave and UK start-ups like Oxford Quantum Circuits);
2. Silicon-based nano-devices with the longest-lived solid-state qubits and offering the powerful prospect of CMOS compatibility for large scale manufacture (e.g. Intel and UK start-ups like Quantum Motion); and
3. Carbon-based devices such as colour-centres in diamond that can be optically addressed, operate up to room temperature and act as atomic scale sensors.

However, our equipment is available for use by a broader scope of technologies.
