We report on the observation of excitation of Majorana fermions in a Nb-InSb nanowire quantum dot-Nb hybrid system. The InSb nanowire quantum dot is formed between the two Nb contacts by weak Schottky barriers and is thus in the regime of strong couplings to the contacts. Due to the proximity effect, the InSb nanowire segments covered by superconductor Nb contacts turn to superconductors with a superconducting energy gap $\Delta^*$. Under an applied magnetic field larger than a critical value…

Anomalous zero-bias conductance peak in a Nb-InSb nanowire-Nb hybrid device.
TLDR
It is shown that this zero-bias conductance peak structure in the Nb-InSb nanowire-Nb hybrid quantum device can persist over a large range of applied magnetic fields and could be interpreted as a transport signature of Majorana fermions in the InSb Nanowire.
Hard Superconducting Gap in InSb Nanowires
TLDR
This study systematically studied how the interface between an InSb semiconductor nanowire and a NbTiN superconductor affects the induced superconducting properties and provides a guideline to induce superconductivity in various experimental platforms such as semiconductor Nanowires, two-dimensional electron gases, and topological insulators.
Hybrid superconductor-quantum point contact devices using InSb nanowires
Proposals for studying topological superconductivity and Majorana bound states in a nanowire proximity coupled to superconductors require that transport in the nanowire is ballistic. Previous works

TLDR
It is demonstrated that epitaxial InSb-Al superconducting island devices, the building blocks for Majorana-based quantum computing applications, prepared using selective-area epitaxy can achieve micron-scale ballistic 1D transport and pave the way for the development of networks of ballisticsuperconducting electronics for quantum device applications.
Coherent Charge Transport in Ballistic InSb Nanowire Josephson Junctions
TLDR
This work reports on a low-temperature transport study of Josephson junction devices fabricated from InSb nanowires grown by molecular-beam epitaxy and provides a clear evidence for phase-coherent, ballistic charge transport through the nanowire-superconductor hybrid devices in the junctions.

A systematic numerical study of the low-energy Andreev spectrum and supercurrents in short and long superconductor–normal–superconductor junctions made of nanowires with strong Rashba spin–orbit coupling, where an external Zeeman field is applied perpendicular to the spin– orbit axis.

Ge/Si nanowire mesoscopic Josephson junctions
TLDR
Studies of proximity-induced superconductivity in undoped Ge/Si core/shell NW heterostructures contacted by superconducting leads reveal high-order resonant multiple Andreev reflections, indicating that the NW channel is smooth and the charge transport is highly coherent.

The successful observation of the superconductivity in the InSB nanowire-based Josephson junction device indicates that InSb nanowires provide an excellent material system for creating and observing novel physical phenomena such as Majorana fermions in solid-state systems.
Majorana fermions and a topological phase transition in semiconductor-superconductor heterostructures.
TLDR
The measurement of the supercurrent through the junction allows one to discern topologically distinct phases and observe a topological phase transition by simply changing the in-plane magnetic field or the gate voltage, which will be a direct demonstration of the existence of Majorana particles.

Supercurrent reversal in quantum dots
TLDR
It is demonstrated that the supercurrent reverses sign is added by adding a single electron spin to the quantum dot by means of local electrostatic gating, which depends on the character of the orbital wavefunctions.

TLDR
The heterostructure proposed is a semiconducting thin film sandwiched between an s-wave superconductor and a magnetic insulator which can be used as the platform for topological quantum computation by virtue of the existence of non-Abelian Majorana fermions.

Giant, level-dependent g factors in InSb nanowire quantum dots.
TLDR
The measurements show that the quantum levels of the InSb quantum dots have giant g factors, with absolute values up to approximately 70, the largest value ever reported for semiconductor quantum dots, which indicates that considerable contributions from the orbital motion of electrons are preserved in the measured InB nanowire quantum dots.
