چکیده
Superconducting joints are one of the key technologies to make Ba1-xKxFe2As2 (Ba-122) superconducting wires or tapes for high-field applications. Herein, were fabricated by a simple cold-pressing method, and joint resistance iron-based was estimated first time. The properties, microstructures, elements distribution in regions investigated. At 4.2 K 10 T, transport critical current Ic 105 A obtained, ratio (CCR= Ic-joint/Ic-tape) 94.6%. On other hand, show very low 2.7x10^-13 ohm self-field at K. Among superconductors (IBS), this work is successfully realize with such high CCR resistance. This shows great potential apply Ba-122 range practical applications, where essential.

Superconducting persistent-current qubit
We present the design of a superconducting qubit that has circulating currents of opposite sign as its two states. The circuit consists of three nanoscale aluminum Josephson junctions connected in a superconducting loop and controlled by magnetic fields. The advantages of this qubit are that it can be made insensitive to background charges in the substrate, the flux in the two states can be det...
متن کاملPersistent current in superconducting nanorings.
The superconductivity in very thin rings is suppressed by quantum phase slips. As a result, the amplitude of the persistent current oscillations with flux becomes exponentially small, and their shape changes from sawtooth to a sinusoidal one. We reduce the problem of low-energy properties of a superconducting nanoring to that of a quantum particle in a sinusoidal potential and show that the dep...
متن کاملPersistent current in small superconducting rings.
We study theoretically the contribution of fluctuating Cooper pairs to the persistent current in superconducting rings threaded by a magnetic flux. For sufficiently small rings, in which the coherence length xi exceeds the radius R, mean field theory predicts a full reduction of the transition temperature to zero near half-integer flux. We find that nevertheless a very large current is expected...
متن کاملSuppression of tunneling in a superconducting persistent-current qubit
We consider a superconducting persistent-current qubit consisting of a three-junction superconducting loop in an applied magnetic field. We show that by choosing the field, Josephson couplings, and offset charges suitably, we can perfectly suppress the tunneling between the two oppositely directed states of circulating current, leading to a vanishing of the splitting between the two qubit state...
متن کاملResonant readout of a superconducting persistent current qubit
Superconducting Josephson junction devices rank among the best candidates for realizing a quantum computer. While the coherent control of quantum dynamics has been demonstrated in these solid-state, macroscopic quantum systems, a major challenge has been to increase the coherence times for these qubits. With an objective to reduce the level of readout-induced decoherence, this thesis work focus...
