Quick Summary

A quantum liquid is a state of matter, specifically a liquid, that exhibits unique behaviors due to quantum mechanical effects at temperatures near absolute zero. The most well-known example is superfluid helium, which can flow without friction.12

This phenomenon, known as superfluidity, arises from quantum mechanics, where a large number of atoms behave collectively. Unlike ordinary liquids, quantum liquids can sustain persistent currents and exhibit other exotic properties. These quantum effects are a significant area of study within condensed-matter physics.12

Such phenomena are also exemplified by superconductivity (completely resistance-less flow of electricity), a low-temperature property of certain metallic and ceramic materials.
