The ability to generate large-scale entanglement is an important progenitor of quantum information processing capability in noisy intermediate-scale (NISQ) devices. In this paper, we investigate the extent which entangled states over large numbers qubits can be prepared on current superconducting We native-graph IBM Quantum 65-qubit $\textit{ibmq_manhattan}$ device and 53-qubit $\textit{ibmq_ro...

A sample holder for high temperature (300 K<T<800 K) measurements in superconducting quantum interference device magnetometers is presented. It is fabricated using aluminum foil and it is appropriate for samples in either solid or powder form. The holder is homogeneous for the gradiometer coil, and this results in a contribution to the background signal that is below the instrument noise at any...

This paper describes a superfluid analog of the superconducting RF SQUID.1 Whereas an RF SQUID is sensitive to magnetic flux, the 4He SQUID (Superfluid QUantum Interference Device) is sensitive to absolute rotation. The device described here exhibits several of the characteristic phenomena of SQUIDs. For example: There is a "staircase" response function. The slope of the staircase response is d...

THE Energy Buncher at the low energy beamline of the superconducting fragment separator (Super-FRS) (Figure 1) at FAIR is a valuable and attractive experimental device for particle identification after secondary reactions. This device will be at the heart of the experimental facility for nuclear and reaction (NuSTAR) studies using radioactive ion beams at FAIR. The dipole, quadrupole and sextup...

Alternating current threshold excitation of space-clamped squid giant axons was measured as a function of frequency, external calcium concentration, temperature (from 10 degrees to 35 degrees C), and hyper- and depolarizing steps. In normal axons there is usually an optimum frequency at about 120 Hz, at which the threshold is a minimum. The threshold rises at both lower and higher frequencies t...

It is shown that the quark mass aligns QCD θ vacuum in such a way that the strong CP is conserved, resolving the strong CP problem. Quantum chromodynamics (QCD) is well established as the fundamental theory for the strong interactions. However, there has been a persistent puzzle with QCD, namely the smallness of the strong CP violation. The most general QCD Lagrangian is given in the form:
