We are aiming to hybridise photons with Rydberg excitons (excited bound states of electron-hole pairs with high principal quantum numbers) to form polaritons. Ryberg excitons are of particular interest due to their large dimensions (~2um) relative to other systems with atom-like structure. This large size causes a strong effect of repulsion between neighbouring excitons. By coupling photons to these excitons via the use of microcavities, we may achieve strong, indirect interactions between photons and thereby build a large quantum network of strongly correlated photons for use in future quantum simulators. The semiconductor chosen for producing the excitons is cuprous oxide (Cu2O) since its 'yellow' excitons have strong binding energies which allows for quantum numbers up to n=25 to be reached.

我们的目的是将光子与rydberg激子（具有高主量子数的电子孔对的激发绑定状态）混合，以形成极性。 Ryberg激子特别感兴趣，因为它们的较大尺寸（〜2UM）相对于其他具有原子样结构的系统。这种大尺寸会在相邻激子之间产生强烈的排斥作用。通过通过使用微腔将光子耦合到这些激子与这些激子，我们可以在光子之间实现强，间接相互作用，从而构建一个强相关光子的大量子网络，以在未来的量子模拟器中使用。由于其“黄色”激子具有较强的结合能，因此选择用于产生激子的半导体是氧化物（CU2O），它允许达到最高n = 25的量子数。
