Abstract: 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.

Abstract: One embodiment describes a memory cell. The memory cell includes a phase hysteretic magnetic Josephson junction (PHMJJ) that is configured to store one of a first binary logic state corresponding to a binary logic-1 state and a second binary logic state corresponding to a binary logic-0 state in response to a write current and to generate a superconducting phase based on the stored digital state. The memory cell also includes at least one Josephson junction having a critical current that is based on the superconducting phase of the PHMJJ and being configured to provide an output corresponding to the stored digital state in response to a read current.

Abstract: Methods and apparatuses are provided for controlling the state of a qubit. A qubit apparatus includes a qubit and a load coupled to the qubit through a filter. The filter has at least a first pass band and a first stop band. A qubit control is configured to tune the qubit to alter an associated transition frequency of the qubit from a first frequency in the first stop band of the filter to a second frequency in the first pass band of the filter.

Abstract: Systems and methods are provided for reading an associated state of a qubit. A first soliton is injected along a first Josephson transmission line coupled to the qubit. A velocity of the first soliton is selected according to a physical length of the qubit and a characteristic frequency of the qubit. A second soliton is injected at the selected velocity along a second Josephson transmission line that is not coupled to the qubit. A delay associated with the first soliton is determined relative to the second soliton.
