Physicists consider the temperature range near absolute zero to be a particularly exciting area for research. Thermal fluctuations are reduced to a minimum. The laws of quantum physics come into play and reveal special properties of materials. Electric current then flows freely without any resistance.

Another example is a phenomenon called superfluidity: Individual atoms fuse into a collective state and move past each other without friction.

These extremely low temperatures are also required to research and harness quantum effects for quantum computing



The cooling device of Jülich’s microscope is based on the process of adiabatic demagnetization.

It was used in the 1930s to reach temperatures below 1 kelvin in the laboratory for the first time. For the operation of microscopes, it has several advantages

  • can cool the microscope just by changing the strength of the electric current passing through an electromagnetic coil.
  • Thus, the microscope has no moving parts and is practically vibration-free


it enables matter to be visualized and manipulated at the level of individual atoms and molecules in many different ways.

“Our new microscope differs from all the others in a similar way to how an electric car differs from a vehicle with a combustion engine."

Until now, researchers have relied on a kind of liquid fuel, a mixture of two helium isotopes, to bring microscopes to such low temperatures. “During operation, this cooling mixture circulates continuously through thin pipes, which leads to increased background noise,”


Scanning tunnelling microscopes capture images of materials with atomic precision and can be used to manipulate individual molecules or atoms.

Thanks to magnetic cooling, their scanning tunnelling microscope works without any moving parts and is almost vibration-free at extremely low temperatures as low as 30 millikelvins.

Consciousness And Quantum Physics

Understanding consciousness and how it fits in the universe is a perennial puzzle for decades. Some call it the holy grail of science.

Quantum physics is able to describe the atomic and subatomic level particles and their properties in ways never before understood, and science is beginning to understand a possible link.



What is Quantum Entanglement?

Quantum Entanglement is a phenomena that describes how the measurements of spin, momentum, and position can all be same between two unique particles.

The main issue is that entanglement can only exist for brief moments because any sort of observation or change in environment can break it.

Entanglement is interesting because it can fit well into other theories as well. One example is Hawking Radiation. The very premise of the theory is that an Entangled Photon Pair is separated at the surface of a Black Hole.

How interesting would it be if humans could be entangled with each other?



Scientists think consciousness is generated by quantum physics.

One of the most important open questions in science is how our consciousness is established. In the 1990s, long before winning the 2020 Nobel Prize in Physics for his prediction of black holes, physicist Roger Penrose teamed up with anesthesiologist Stuart Hameroff to propose an ambitious answer. The brain’s neuronal system forms an intricate network and that the consciousness this produces should obey the rules of quantum mechanics – the theory that determines how tiny particles like electrons move around. This, they argue, could explain the mysterious complexity of human consciousness.
