 Our group is all about atoms, photons, and their properties. We are particularly curious about the interaction between photons and atoms, how to tailor the interactions to various applications and harness their special properties. As experimentalists, we conduct experiments in our labs at Durham University but our group also has a strong background in computational and theoretical quantum & atomic physics. As a team, we are a small group of kind and curious researchers immersed in the wider Quantum Light and Matter section at Durham Uni, and we are always welcoming new PhD students, postdocs or academic visitors. Please see our open positions at the bottom of the page and get in touch with Stuart Adams for any queries ([email protected]).

 Taking this one step further, we have shown that Rydberg polaritons can also be used to form the fundamental building blocks of a quantum computer, a so-called qubit [PRL **127**, 063604 (2021)](https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.127.063604). We have shown that qubits based on Rydberg polaritons are robust against atom loss from the polaritonic mode, and provide a very convenient optical readout by simply mapping the polaritons back into photons. And as we already know from our previous work, these collective Rydberg qubits can interact via Rydberg-interactions mediated by the matter component of the polaritons. This gives us all the tools that we need to use Rydberg polaritons in applications. One avenue of our future research therefore is continuing to explore Rydberg polaritons for applications ranging from quantum information processing via tests from the foundations of quantum mechanics to applications in sensing.
