A study conducted by an international team of specialists, brings the era of quantum computers capable of operating at room temperature. This was reported in the publication of the National research technological University “MISIS”.
Quantum computing systems operate on quantum bits, or qubits. They can take simultaneously a value and a logical zero, and logical units. Therefore, with the increase in the number of used qubits, the number of simultaneously processed increases exponentially.
To date, the existing quantum systems, the most common qubits in superconducting materials or single atoms in optical traps. However, such systems require ultra low temperatures, resulting in huge costs for permanent cooling.
The new study opens the way for qubits operating under normal conditions. The meeting was attended by Russian experts from nust “MISIS”, as well as their colleagues from Sweden, Hungary and the USA.
Scientists have found a way to create a stable solid-state qubits in silicon carbide (SiC). Experts managed to find out what structural feature allows these qubits to operate at room temperature.
“Silicon carbide and had previously been considered as a promising material for the creation of qubits, however, in some cases, these qubits immediately “burned out” at room temperature. The task of scientists was to find out if any modification of the material would be stable. Development opens up new perspectives in the creation of the quantum computer, which worked stably at room temperature“, – stated in the message.
