"A new qubit design combines a gyrator with superconducting circuits to intrinsically protect the qubit from noise" (Phys.org, A Superconducting Qubit that Protects Itself) (Figure I:).

The qubit is equipped with an electromagnetic protective field. 

The fact is that when the qubit is transporting data, it must touch anything. If qubit touches the wall of the channel, it will be lost its data. So that's why the addictive way to make the quantum computer is to replace physical channels, where the qubit is traveling by using the virtual channels. In this case, the qubits are traveling between the quantum antennas in the protected space between two layers. But the problem is how to protect the data inside the qubit.

When a quantum computer operates the data is transported in qubits. So if we want to compare the qubits with something in the macroworld or our size world, we can say that the qubit is the hard disk, where the data is stored. The first data will store in a qubit, and send it will send to the target, where it is unloaded. The problem is that when the qubit is touching the sensor, the data that is stored in it is gone. Same way if some electromagnetic field will affect qubit during its journey, it would disturb the data. 

If we are thinking about the quantum computer as the voltage meter, where certain levels of voltage mean a certain level of a qubit, there is the possibility to protect data by simply leaving enough space between those levels of qubits. The data inside the qubit can be protected also by shooting them through the channels, which is protecting them against an outcoming electromagnetic field.

One version of this kind of system is the laser-ray, which is shot behind the particle, which acts as a qubit to the other particle, where it will transport the oscillation of the source particle to the other particles. The qubit particle can also shoot in the area, which is between the graphene layers. Or those layers can virtualize by using magnetic fields and ions. In this case, the plasma fields can also operate as the protector for qubits, which are moving between those layers.

In the article what is linked below this text is described the new qubit, which is equipped with the synthetic magnetic field. That synthetic magnetic field will give the qubit itself the protective layer. So the qubit is equipped with a protective shield against electromagnetic noise. The electromagnetic shield will protect the data inside it. When the qubit can protect itself the system itself would be lightweight.
