The lines of flux in a current carrying conductor are a circular in shape. Every current carrying conductor will induce lines of flux. These lines of flux in magnetic fields are similar as electrical current in electrical fields. The flux can be quantized in terms of Weber. The denoted symbol for lines of flux is φ (pi).
Zero flux current transformer
ActiveCN224287987UTransformers/reacts mounting/support/suspensionTransformersElectrical engineering technologyElectrical conductor
This utility model relates to the field of electrical engineering technology and discloses a zero-flux current transformer, including a housing, an insulating bushing, a base, and a transformer body. The transformer body is vertically mounted inside the housing, and a primary conductor is installed inside to carry high-voltage direct current. A zero-flux coil is installed at the upper end of the transformer body to sense the magnetic field generated by the current in the primary conductor and output a secondary current. The zero-flux coil is located inside a shield and grounded to improve measurement accuracy and stability. The transformer is filled with SF6 gas for electrical insulation, and a silicone rubber coating is provided on the outside of the zero-flux coil as a buffer layer to protect the coil from the influence of internal gas pressure. The transformer body is connected in series in a DC circuit system through the primary conductor, and the secondary current is introduced into the zero-flux electronic module via a cable to output a secondary signal. This utility model improves the measurement accuracy and stability of the current transformer, enhances safety and reliability, and is suitable for high-voltage direct current environments.

Device for a resonant cat-qubit circuit and quantum measurement method
A non-linear superconducting quantum circuit having a first mode and a second mode is disclosed, wherein the first and second modes have respective resonant frequencies. The circuit is configured such that the resonant frequency of the second mode is substantially 2N times the resonant frequency of the first mode when a predetermined current of a constant intensity is applied to the circuit. The circuit intrinsically performs a resonant 2N-to-1 photon exchange between the first and second modes, with N being a positive integer, and thus improving the circuit. When this circuit receives a predetermined current and when the second mode is driven appropriately, the circuit can stabilize a cat-qubit. In a symmetrical version of this circuit, a flux line has been developed to allow RF coupling to the second mode and not to the first mode, allowing the stabilization to be turned off and quantum measurements to be performed.
