Theorists use cloud-based Bose–Einstein condensate to study tunnelling

In this episode of the Physics World Weekly podcast I am in conversation with two theoretical physicists who have put their predictions to the test by doing experiments using a remotely controlled Bose–Einstein condensate (BEC) thousands of kilometres away.

They are Ippei Danshita of Kindai University and Daichi Kagamihara at Chuo University. They are both in Japan, whereas the cloud-based Oqtant BEC they used is located in the US and operated by the quantum-technology company Infleqtion.

Kagamihara and Danshita explain why they decided to do remote experiments and how using Oqtant improved their understanding of how anomalous tunnelling affects collective excitations of BECs. They also talk about how the remote-control process works and whether they will make future forays into experimental physics.

The duo and their colleagues describe their research in “Observation of the influence of anomalous tunneling on collective excitations via a cloud experiment platform for Bose–Einstein condensates”.
