Why are people who work with quantum systems interested in quasiparticles? 

“Scientists found that adding a once-dismissed particle, the “neglecton,” allows Ising anyons to perform universal quantum computing.

Neglectons look like photons. Both of them are donut-shaped particles. And that raises a question: could a photon be some kind of skyrmion? More about these topics at the end of this text. 

Quasiparticles are electromagnetic fields and quantum phenomena that act like a “real particle”. There are many types of quasiparticles, and the thing that makes them interesting in quantum computing is that those particles are extremely rare. Quasiparticles don’t exist for a long time. And there are no long-term versions of those things. That means the wave movement that comes from other particles doesn’t disturb quasiparticles as it does other particles. Because quasiparticles are so-called unique particles, they can create quantum entanglement without causing quantum noise. 

Same way. When a quasiparticle sends a wave movement, that wave movement causes resonance in a similar way to a receiving quasiparticle. And because there are no other particles that send wave movement with a similar wavelength as those quasiparticles, that thing makes it easier to transmit information. In other particles. Like quarks or fermions, the wave movement that reflects from other similar particles can disturb the data transmission. 

Anyons and neglectons are the most interesting quasiparticles from the point of view of quantum computing. 

“In physics, an anyon is a type of quasiparticle so far observed only in two-dimensional systems. In three-dimensional systems, only two kinds of elementary particles are seen: fermions and bosons. Anyons have statistical properties intermediate between fermions and bosons. In general, the operation of exchanging two identical particles, although it may cause a global phase shift, cannot affect observables. Anyons are generally classified as abelian or non-abelian. Abelian anyons, detected by two experiments in 2020, play a major role in the fractional quantum Hall effect.” Wikipedia, Anyons)

Sometimes, frozen anyons are introduced as a solution for quantum entanglement problems in quantum computing. 

“Among the leading candidates for building such a computer are Ising anyons, which are already being intensely investigated in condensed matter labs due to their potential realization in exotic systems like the fractional quantum Hall state and topological superconductors,” said Aaron Lauda, professor of mathematics, physics and astronomy at the USC Dornsife College of Letters, Arts and Sciences and the study’s senior author.”(ScitechDaily, Lost Particle Resurfaces As the Key to Universal Quantum Computing)

“On their own, Ising anyons can’t perform all the operations needed for a general-purpose quantum computer. The computations they support rely on ‘braiding,’ physically moving anyons around one another to carry out quantum logic. For Ising anyons, this braiding only enables a limited set of operations known as Clifford gates, which fall short of the full power required for universal quantum computing.” (ScitechDaily, Lost Particle Resurfaces As the Key to Universal Quantum Computing)

Neglectons are the previously overlooked quasiparticles. Those quasiparticles look like a donut, and that makes them essential for data transmission in the quantum computer. The neglecton can spin ahead of the data transmitter. And if the system can spin it, that allows the laser to send information to that particle. Ot the laser beam, or information carrier that travels through those neglectons. And that thing acts as a quantum gate where information can travel between two superpositioned and entangled neglecton particles that are positioned into graphene or some other 2D structures. Which turns bits  into qubits.

So what if a photon is a skyrmion? 

We can say that the neglecton is something that looks like a skyrmion or photon. The thing that makes frozen anyons problematic is that they can form only in the condensed material. The condensed material means that the particle is in its minimum energy level. That makes energy travel to those particles. And that forms a skyrmion around it. The skyrmion is the impact wave that forms when energy travels to those particles. The neglectons shape causes an idea that maybe the photon is also some kind of skyrmion. So could there be some kind of thing in the middle of the photon that makes the wave movement travel into it. That it make a skyrmion that we know as a photon? 

Skyrmions form around an object when energy jumps back from some structure. And the outside energy interacts with those reflecting waves. That forms a ring-shaped structure around the object. So, if a photon is some kind of skyrmion, that makes this model interesting. 

There are two versions of things. That could make that kind of skyrmion. The first one is the dot-shaped object.  Another one is the stick-shaped object. That means the hypothetical graviton, the hypothetical particle that transmits gravitation, could be in the center of that donut-shaped structure. Or another thing is that. The hypothetical superstring can travel through the photon. Those things are a good explanation for the photon's interesting donut-shaped structure.
