Theoretical physicists conduct remote quantum tunnelling experiments using cloud-based condensate

Theoretical physicists based in Japan have conducted quantum mechanics experiments using a cloud-operated research platform located thousands of kilometres away in the United States, Physics World reported. Ippei Danshita of Kindai University and Daichi Kagamihara of Chuo University ran the tests to study quantum phenomena remotely. [1]

According to Physics World, the researchers accessed a cloud-based Bose-Einstein condensate system named Oqtant, which is operated by the quantum technology company Infleqtion. The remote experimental setup allowed the theoretical physicists to test their predictions regarding how anomalous tunnelling affects quantum systems. [1]

A Bose-Einstein condensate is a state of matter created when a low-density gas of bosons is cooled to temperatures near absolute zero. Under these extreme conditions, a large fraction of the constituent particles occupy the lowest available quantum state, allowing microscopic quantum phenomena such as wavefunction interference to become visible on a macroscopic scale. [3]

Physics World reported that the remote experiments helped the researchers improve their understanding of anomalous tunnelling mechanisms. The successful use of the cloud-based Oqtant platform demonstrates that theoretical physicists can directly control distant hardware to test complex quantum physics models. [1]
