摘要： One aspect of the present invention includes a Josephson magnetic memory system. The system includes a superconducting electrode that conducts a read current. The system also includes a hysteretic magnetic Josephson junction (HMJJ). The HMJJ can store a binary value and convert superconducting pairs associated with the read current flowing through the HMJJ from a singlet-state to a triplet-state. The system further includes a write circuit magnetically coupled to the HMJJ and configured to write the binary value into the at HMJJ in response to at least one write current and a read circuit configured to determine the binary value stored in the HMJJ in response to application of the read current to the HMJJ.
