Magnetism and quantum computers.


"Researchers at the University of Liège have developed a groundbreaking method to rapidly generate quantum superpositions, known as NOON states, using a combination of geometry and quantum control. This innovation drastically reduces preparation time from minutes to milliseconds, opening the door to practical applications in quantum computing and ultra-precise sensors.

Quantum computers are complicated systems. The quantum computer uses qubits for the data-handling process. Qubits are superpositioned and entangled particles to transport information inside them. Normally those systems use superpositioned and entangled photon pairs. The system traps photons in the frame. 

And then it starts to make the superposition and entanglements. That kind of quantum entanglement is quite hard to control because photons are so weak, that gravitational waves can affect them. 

That makes those qubits a little bit unstable. In a quantum computer, the system drives information into the particle, and then superposition and entanglement start to transport information between two superpositioned and entangled particle pairs.

"An illustration depicts an unexpectedly strong attraction between electrons in neighboring lattice sites within a 1D chain of copper oxide, or cuprate – a material that conducts electrical current with no loss at relatively high temperatures in their 2D counterparts. In a recent study, Stanford and SLAC scientists used X-rays to examine the behavior of pairs of spinons – quasiparticles that represent an electron’s spin. This experiment provides further evidence of an unusually strong attractive force not captured by the Hubbard model, the leading theory for predicting electron behavior in solids. Authors say the model fails to explain electron dynamics in cuprates, even in simplified, one-dimensional systems.

Things like atoms and electrons would be better particles for superposition and entanglements. But their problem is: how to protect those qubits against changes in a magnetic field. If the system can protect superposition and entanglement that makes it possible to transport information between those two particles.  

The new observations about magnetism make it possible to create new fundamental states of quantum technology. What if we could make the cylinder-shaped Hall field or Hall effect and control that field? If we, or researchers, can make the Hall effect that forms a field. 

That is slight inside. They can create a tube that protects the quantum entanglement inside it. The horizontal Hall effect is possible. That thing can make a new type of protective field that denies the internal disturbance. In some wild ideas, the Hall effect field can used as a Tipler time machine, or its quantum version.

In that case the high-speed spinning magnetic field around the quantum channel. The idea is that The Hall field around those nanotubes will slow the time. In those nanotubes, the data travel between two superpositioned and entangled particles. If the fast spinning field surrounds those quantum channels that should cause time dilation in the nanotube. And that gives the quantum computer more time to operate. 

Another interesting thing is magnet-free states in twisted crystals. Those magnet-free states make it possible to create electron and atomic-scale quantum entanglements. The complex system entanglements can be the key to the new types of quantum systems. Information can travel between those two complex systems through their quantum fields. 

And if the system can make quantum entanglement using electrons or atoms it makes it easier to control those qubits. But the problem is the magnetic states. The system must protect those superpositioned and entangled particles against magnetic fields and especially against changes in the magnetic fields.
