#AIHRL Laboratories has unveiled a silicon quantum processor featuring a cryogenic CMOS controller capable of performing real-time quantum error correction without relying on external room-temperature electronics.
The system architecture consists of an 18-qubit chip, a cryogenic controller, and a superconducting ribbon cable.
According to the researchers, control errors were reduced by a factor of 10 compared to previous demonstrations using this qubit technology, while individual gate operations were completed in under one microsecond.
As the number of qubits increased under a repetition-code scheme, the system achieved roughly a fivefold suppression of errors. HRL says this marks the first demonstration of quantum error correction performed entirely by a cryogenic controller, with no involvement from room-temperature electronics.
