In order to build a random number generator, we need to estimate the amount of randomness it has. Our aim to estimate the min-entropy of a finite sample of data using the Bayesian and Frequencist estimators.
Aim to generate random numbers by performing a homodyne measurement of the quantum vacuum state.
This project aims to be the first in the world to use the radiation pressure forces of laser beams to coherently levitate a macroscopic mirror. Applications of this scheme include precision metrology and test of new physics theories.
This projects aims to construct an ultra-sensitive magnetic field sensor from a whispering gallery mode crystal resonator.
We aim to generate random numbers by performing orthogonal quadrature homodyne measurements without actually knowing or trusting the quantum state that we are measuring.
Student will build and characterise a new source of quantum squeezed light genearted from an optical parametric oscillator
Student will use electro-optic feedforward techniques to implement noiseless linear amplification of information carrying laser light
A quantum state has "coherence" if it is in a superposition of some classical states. In some way, coherence measures the quantumness of that state. We aim to study the coherence of simple systems and also establish a relationship between coherence and quantum metrology.
Student will develop a source of laser light at 775nm that will be utilised for pumping of squeezing cavities
When two point sources of light are close together, we just see one blurry patch. This project aims to use coherent measurement techniques in quantum optics to measure the separation between the point sources beyond the Rayleigh's limit.
