We studied a qubit based on flux-pinning effects in ∆H=∆B region of a superconductor. When volume defects are many enough in a superconductor, ∆H=∆B region on M-H curve is formed, which is the region that increased applied magnetic field (∆H) is the same as increasing magnetic induction (∆B). Magnetization (M) is constant in the region by 4πM = B H. Here we show that the behavior of fluxes in ∆H=∆B region can be a candidate of qubit. Pinned fluxes on volume defects would move as a bundle in the…

Increases of a Diamagnetic Property by Flux-Pinning in Volume Defect-Dominating Superconductors.

Whereas there are two critical fields that are H$_{c1}$ and H$_{c2}$ in the ideal type II superconductor, there is another critical field H$_{c1}'$ defined as the field showing the maximum

Upper Critical Field Based on the Width of ∆ H = ∆ B region in a Superconductor

We studied a method of measuring upper critical field (Hc2) of a superconductor based on the width of ∆H = ∆B region, which appears in the superconductor that volume defects are many and dominant.

Flux-Pinning Behaviors and Mechanism According to Dopant Level in (Fe, Ti) Paticle-Doped MgB$_2$ Superconductor

We have studied flux-pinning effects of MgB2 superconductor by doping (Fe, Ti) particles of which radius is 163 nm on average. 5 wt.% (Fe, Ti) doped MgB2 among the specimens showed the best field

Anisotropic interactions of a single spin and dark-spin spectroscopy in diamond

Experiments on single nitrogen–vacancy (N–V) centres in diamond, which include electron spin resonance1, Rabi oscillations2, single-shot spin readout3 and two-qubit operations with a nearby13C

Coherent control of macroscopic quantum states in a single-Cooper-pair box

A nanometre-scale superconducting electrode connected to a reservoir via a Josephson junction constitutes an artificial two-level electronic system: a single-Cooper-pair box. The two levels consist

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

Electron holography observation of vortex lattices in a superconductor.

It was found that a 2D array of tiny regions, where the phase distribution rapidly changed, coincided spatially with the spots observed by Lorentz microscopy, and these regions were identified to be quantized vortices each having a flux of h/2e by comparing with theoretical calculations.

Theory of the Motion of Vortices in Superconductors

The theory of the motion of vortex lines in the mixed state of type II superconductors is derived on the basis of a local model that is a generalization of the London theory. It is believed the model
