Combination tuning probes for slide screw load pull tuners allow larger frequency coverage Fmax/Fmin and higher GAMMA beyond the capacity of existing tuning probes. This is done by combining two or more equally or unequally long tuning slugs into a combination probe, the slugs being mounted in the same mobile tuner carriage using two or more independent vertical axes. To avoid spurious resonance phenomena the tuning slugs are driven parallel vertically in close proximity or sliding on each-other, are linked to each-other and guided appropriately allowing smooth, un-inhibited and continuous vertical movement of the metallic bodies.

A method to evaluate a semiconductor-superconductor heterojunction for use in a qubit register of a topological quantum computer includes (a) measuring one or both of a radio-frequency (RF) junction admittance of the semiconductor-superconductor heterojunction and a sub-RF conductance including a non-local conductance of the semiconductor-superconductor heterojunction, to obtain mapping data and refinement data; (b) finding by analysis of the mapping data one or more regions of a parameter space consistent with an unbroken topological phase of the semiconductor-superconductor heterojunction; and (c) finding by analysis of the refinement data a boundary of the unbroken topological phase in the parameter space and a topological gap of the semiconductor-superconductor heterojunction for at least one of the one or more regions of the parameter space.

Low loss high directivity wire couplers use a transmission airline structure and a low diameter coaxial cable ending in a wire loop sensor, which is inserted into an elliptically formed conical opening of the ground wall of the transmission line and protrudes into its cavity leading into a coupled and an isolated port. Lower, capacitively induced, electrical currents, because of the protruding ground edges of the conical or recessed openings, compared with the unperturbed antiphase magnetically induced currents, lead to controlled higher directivity in a frequency range up to at least 170 GHz.

A low radio frequency electro-mechanical load pull impedance tuner uses four rotary, remotely controlled variable shunt capacitors and three fixed series transmission lines to create up to 10.sup.8 independently controllable impedance states at each frequency covering the entire Smith chart in the frequency range between 1 and 10 MHz; the capacitors and control motors and gear are immersed in high epsilon dielectric fluid inside individual sealed containers. Appropriate Error Function-based optimization algorithms, allow fast impedance tuning at the fundamental frequency at the output of DUT's operated in high gain compression. Stepper motors, drivers and control software are used to remotely control the variable shunt capacitors of the tuner and allow it to be automated, pre-calibrated and used in an automated load pull measuring setup.
