Experts Quantum computing with those who have had the opportunity to speak, such as Spanish physicists Ignacio Cirac either Juan José García RipollThey argue that quantum computers will be able to make great contributions when they are capable of amend your own mistakes. The main problem they face in this area is noise, understood as the disturbances that can alter the internal state of the cubits and introduce calculation errors. The strategy for which many of the research groups that are involved in the development of quantum computers are opting for monitoring the operations carried out by the cubits to identify real -time errors and correct them. The problem is that from a practical point of view This strategy is very challenging. Logical cubits represent a way to overcome the difficulty involved in the use of hardware or physical cubits, which are extremely noise sensitive, and, therefore, prone to make mistakes. Each logical cubit is constructed abstractly on several physical or hardware cubits, so that a single logical cubit encodes a single cubit of quantum information, but with redundancy. It is precisely this redundancy that allows to detect and correct the errors that are present in the physical cubits. Anyway, the researchers will have one more tool to deal with the errors of quantum computers. It can even be the most powerful resource that they currently have at your fingertips: the Neglectón. Universal quantum computers are one step closer One of the most promising research fields in this area is topological quantum computing. Its purpose is to protect the delicate quantum information that the cubits work coding it in the geometric properties of exotic particles known as ISING anions. An important note before moving forward: in condensed physics an anion is not the same as in chemistry. In fact, Ising’s anions are quasiparticles that, in theory, arise in some two -dimensional materials. Its existence has not yet been demonstrated experimentally, so they are a theoretical result at the moment. It seems a complicated concept, and it is, but in this article we do not need to deepen much more. What we do need is that Ising’s anions They are presumably much more robustand, therefore, resistant to errors that traditional cubits. In practice this implies that moving some anions around others in a specific way should allow researchers to carry out logical operations with them. This is the reason why they are so attractive in quantum computing. And, in addition, they have another great advantage: this configuration is largely immune to external noise. Ising’s anions are quasiparticles that, in theory, arise in some two -dimensional materials Currently, Ising’s anions are thoroughly investigating in the condensed matter laboratories of the entire planet because they are one of the main candidates to participate in the construction of universal quantum computers, and, therefore, immune to errors. Aaron Lauda, ​​professor of mathematics, physics and astronomy at the University of Southern California (USA), Holds the following: “By themselves, Ising’s anions cannot perform all the necessary operations for a general purpose quantum computer. The calculations they support are based on the ‘braided’ (branding), And they require physically moving anions around each other To carry out quantum logic. For Ising’s anions, this braided only allows a limited set of operations known as Clifford doors, which fall short with respect to all the power required for universal quantum computing. “ Fortunately, the research team led by Lauda has found a way to transform ISING anions into universal structures that are capable of performing any quantum calculation through braided. Its solution for the moment is only theoretical, but its potential is enormous. The surprising thing is that what they propose is to resort to a new type of anion known as Neglectón that was initially discarded when it was “discovered” in the theoretical framework. In fact, Neglelectón has gone from being a mathematical waste to be the new hope of quantum computers. In theory when combining Ising’s anions and neglect, universal quantum computing will be possible through braided. According to Aaron Lauda Only one neglect is needed because it remains in the stationary or static state while the calculations are carried out by braiding Ising anions around them. It is a surprising conclusion. One last note to conclude: The neglect is not a fundamental particlesuch as the electron or the quark; It is a theoretical quasiparticle that arises from the collective behavior of many other particles in a two -dimensional system. Let us trust that it is consolidated as the definitive tool that will allow researchers to carry quantum computing from theory to practice in a robust and efficient way.
