Abstract
A permanent defect qubit repair system using a redundant repair circuit at a quantum circuit level, includes: automatic test equipment configured to provide a fault address table with information of a permanent fault address (FA) and a spare address (SA) for replacing the FA to a quantum memory; a redundant repair circuit configured to constitute a circuit to repair a permanent defect qubit consisting of an address comparison and address replacement process and transfer an updated memory address to an address routing circuit; and the quantum memory comprising the address routing circuit configured to receive the updated memory address from the redundant repair circuit and then route the updated memory address to a memory cell according to an address value.
