Quantum Liquid Fully Reconstructed by Scientists

Physicists have reconstructed the full state of a quantum liquid, consisting of ultracold atoms trapped on an atom chip, by observing how their fluctuations spread over time. The breakthrough offers promise for technological advancement in quantum computing and quantum sensors. The research team performed a tomography of a quantum system, creating two "copies" of the system and revealing the two copies' correlations to infer the initial quantum state of the system and extract its properties.
