Scientists have become convinced of the existence of a new type of quasiparticles: they can be used to create topological quantum computers, scientists hope.
Alexey Ustinov and Ilya Besedin from NUST MISIS with colleagues tried to find traces of the existence of doubloons in the operation of a quantum simulator of 11 superconducting qubits.
It is noted that the doubloons mean hypothetical quasiparticles in the form of a pair of photons. They are acted upon by a kind of analog of repulsive forces, which makes electrons and other charged particles move away from each other.
The authors emphasize that this form of doubloons can be used to create classical light computers, as well as new types of qubits.
During the work, the authors adjusted the connections between the memory cells of the quantum simulator in such a way that doubloons were to appear inside them. The researchers then tried to detect them inside the simulator and study their properties in a real quantum system.
As a result, the authors found out that doubloons can arise in the form that they can be used to create topological quantum computers and implement other problems associated with the creation of new generations of computing devices.
