Quantum Technology

We aim to investigate many body interactions and entanglement for ultracold Sr atoms trapped in a 3D optical lattice. The atoms interact via dipole-dipole interactions induced on low lying states, e.g. on the 5𝑠5𝑝3P0 → 5𝑠4𝑑3D1 transition. The dipole moment could be as large as 4 Debye, much larger than obtained in typical ultra cold molecules. The interaction can give rise to phenomena like superradiance and subradiance. Supradiance has got immense interest due to its applications in next generation optical clocks, whilst subradiance has the potential to be used as quantum memories. Quantum memories are key to building a universal quantum computer. Entangled ensembles are crucial to overcoming standard quantum limit for a quantum sensor.
