Introduction to Quantum Levitation

How it works? Important Facts and more

You’ve probably heard about the phenomenon of Quantum Levitation, but aren’t sure what it is, or how it works. Here are some important facts about this fascinating phenomenon. To begin, it works by causing electrons to flow easily in a material called a superconductor. In addition, the magnetic field inside a superconductor cancels out when it is close to the material’s surface. As a result, the net magnetic field lines bend around the superconductor.


Quantum levitation is a phenomenon in which a superconductor can hover above a magnetic field. This phenomenon occurs when electrons within a superconductor are in pairs and have opposite magnetic poles. The resulting neutral state enables electrons to move freely, and without resistance. This property of superconductors is the key to the phenomenon. But achieving this state of superconductivity is not an easy task.

One way to harness this property is to cool a superconductor at a lower temperature. This can be achieved by cooling the superconductor using liquid nitrogen, which is readily available.

Diamagnetic levitation

Diamagnetic levitation has a variety of applications, from guiding particles to trapping microdroplets. It can be applied to both liquids and air. It has also been used to power wireless sensors for structural health monitoring systems. But how exactly does diamagnetic levitation work?

The process involves diamagnetism, which is inherent to many materials. Several applications have been developed using diamagnetic levitation, including simulations of microgravity environments for biological processes. It can also be used to selectively manipulate microparticles inside microfluidic devices. Furthermore, friction is a major concern in microactuators and sensors, and diamagnetic levitation provides a solution.

The concept of diamagnetic levitation dates back to 1845, when Michael Faraday coined the term. A few years later, William Thomson demonstrated the feasibility of the concept, contradicting Earnshaw’s theorem. This was a breakthrough in the field of magnetism, as stronger magnetic materials were now available. Two scientists were able to test Thomson’s prediction experimentally, W. Braunbeck and A.H. Boerdijk.

Casimir force

The Casimir force is the most fundamental concept in quantum physics. It is an entanglement of two or more elementary particles with a high-speed attraction between them. It is also the basis for quantum levitation. It was first proposed in the early 1900s by Robert L. Forward. This effect is produced when two conducting sheets in parallel planes are joined by a wire, and their charge is maintained equally by a voltage source. The adjacent sheets are pulled together by the Casimir force, while electrostatic repulsion opposes this interaction. Similarly, a vacuum-fluctuation battery can convert van der Waals potential energy into electrical energy.

The Casimir force can be reproduced by stochastic electrodynamics. This method reproduces the Casimir effect without the use of explicit quantization. However, its physical implications remain controversial.


Quantum levitation is the ability of an object to move through a magnetic field. It is the same concept that makes ferromagnets levitate. But in order to make it work, you need to use a magnetic field and non-ferromagnetic materials. Non-ferromagnetic materials are more resistant to the magnetic field than ferromagnetic ones and also have lower eddy currents. One of the best materials to use in this process is litz wire, which gives the best results. Aluminium plate also works well for the purpose. You can also use a linear induction motor to propel the object.

In addition to being able to move without any friction, quantum levitation is a stable process. In theory, an object can levitate indefinitely without losing any energy. However, it must have a low enough temperature to be lossless.

Feedback loop

Quantum levitation can be used in a number of industrial applications. Its underlying principle is based on the use of magnetic fields that are attracted to each other. These fields are used to drive an electromagnet actuator that levitates an object. The current flowing through the electromagnet is controlled by a controller based on the position of the object.

The report includes several short papers describing magnetically levitated systems, which are typically magnetic linear drives and trains. These papers are indexed separately elsewhere in the data base.
