Quantum particles can be divided into two types: fermions and bosons. When cooled down to near-absolute zero temperatures, bosons can condense together into a collective state of matter called a Bose-Einstein condensate where they occupy the same quantum state (e.g. same place and velocity simultaneously). This state of matter allows us to observe remarkable phenomena such as superconductivity – the ability to conduct electric energy with zero resistance. One of the greatest challenges in physics has been to realistically create a Bose-Einstein condensate using photons, which would have significant applications in laser and even solar panel technology.
