Our quantum optics research is focused on the theory of light-matter interaction. Our aim is to understand and develop techniques to use quantum emitters with engineered light-matter interaction to produce new types and useful states of quantum light. This can have applications in quantum computing, communication and metrology. We also study these platforms to understand their fundamental quantum many-body physics.
Our research is focused on investigating and understanding the quantum many-body physics of quantum optical systems. These are systems where photons interact with one another through a nonlinear medium — usually atoms or artificialy atoms. These systems are difficult to model and understand for a number of reasons: they are quantum systems whose Hilbert space grows exponentially with the number of particles and they are open systems that are often driven by external sources of light, e.g., lasers.
We use a number of different theoretical techniques to model these systems including: Bethe Ansatz scattering matrix techniques, which can give analytic insight into the behaviour of these systems, as well as numerical techniques such as Matrix-Product State methods.
Although we are a theory group, we also aim to work with experimentalists. We look to work with experimental groups in Australia and around the world to observe predictions we make with our theory. We also use these collaborations to further understand different quantum optics platforms.
The Quantum Optics Theory group is led by Dr Sahand Mahmoodian. For any enquiries or opportunties, please get in touch via email.
