TRANSPORT AND INTERACTION OF RB87 ATOMS IN A DILUTION FRIDGE

Abstract

Superconducting qubits are capable of performing significantly faster computation compared to atomic qubits. However, the microseconds lifetime of the qubit is still significantly shorter compared to atomic states that could last up to seconds. By combining both superconducting and atomic systems, we can achieve fast computation in the superconducting qubits and stable storage in the atomic states. In our project, we aim to produce a strongly coupled atom-superconductor system that allows for fast state transfer from a superconducting qubit to an atomic state. Here, we describe the experimental setup involved in cloud generation, magnetic transport of the cloud over 70cm and the hardware behind our cryogenic system for the superconducting circuit. We have successfully transferred atoms to the fridge and expect N=1E8 87Rb atoms trapped near the mK cold plate. We plan for the trapping of the cloud to a superconducting 3D cavity to study its coupling strength. This will then pave the way for an actual state transfer from a superconducting qubit to the atoms.
