Quantum science and technology of atomic clocks. Atomic clocks are very accurate but very large and resource hungry. The aim of the project is to make a prototype for a semiconductor version, and make predictions about how small and cheap they might become.
The atomic clock is a mature quantum technology that provides sophisticated but large and resource-hungry frequency standards with remarkable levels of precision and accuracy. The idea is that a clock based on an oscillator and counter (like a pendulum and the hands on the clock-face) must be “disciplined” by periodically checking against a natural phenomenon (like the midday sun). The benefit of the free atom in vacuum as the natural standard against which to discipline the frequency of a quartz oscillator is that the atomic frequency is independent of time and position, and the hyperfine transitions for alkali vapours are extremely regular and sharply defined.
Entry requirements: All applicants should have (or expect to obtain) a first class or high upper second degree. Applicants must be from the UK or EU. If English is not your first language, please copy of a valid IELTS certificate (from the past 2 years), 6.5 overall with 6.0 minimum in each band).
