Specialists of the Russian Quantum Center obtained a patent for the physical implementation of a quantum computer based on qudits, which can have more than two states (0, 1, 2, and others) simultaneously. Qubits that can be in two states (both 0 and 1) are also used in quantum computing.

The patent will allow specialists to increase the power of a quantum computer. One of the approaches involves replacing qubits with an equivalent number of qudits. In another approach, specialists use additional levels of qudits instead of individual auxiliary qubits to perform intermediate calculations.

According to the co-inventor Alexey Fedorov, who heads the Quantum Information Technologies group at RQC, studies have shown that “during the implementation of quantum algorithms, qudits can significantly save the resources of quantum processors, which is especially important for the current generation of devices.” In the near future, the scientists plan to apply for international registration.
