The very first Quantum Knots

Scientists by manipulating magnetic fields, managed to manipulate quantum materials into complex shapes, to advance the development of ultra-fast, stable quantum computers.

The quantum knot produced for the first time, by a collaboration of research teams headed by Prof. Mikko Möttönen (QCD Labs, Aalto University) and Prof. David Hall (Hall Labs, Amherst College).

This type of knot, reported in Nature Physics, formed in a quantum gas, also referred to as a knot soliton.

The knots are tied in a Bose-Einstein condensate (BEC) that is an atomic gas with superfluid properties. The created structure realizes the celebrated Hopf fibration for the first time in the context of quantum physics and quantum mechanics.

In this video, scientists illustrate the structure of the first quantum knot ever tied in quantum matter.
