Topological super conductors are a class of superconducting materials characterized by sub-gap zero energy localized modes, known as Majorana boundary states (MBSs). These materials are promising for the development of electronics, optics, quantum computing and other technologies.
Despite their importance in both fundamental research and applications, natural TSCs or Topological Superconductors are currently very rare.

In general super conductors are theoretically useful for many applications that involve generating and carrying electrical currents with very low energy losses.
Most chemical elements can become superconductors at sufficiently low temperatures or high pressure, however it is rarely practical to cryogenically cool or compress the conductive elements of most commercial products.
Topological conductors support superconductivity across their surface while being insulating in their interior. Due to their exotic material properties they are expected to conduct electricity with very little resistance, somewhat akin to regular super conductors but without the need for the incredibly chilly temperatures or high pressures associated with more common materials.

While they are the subject of ongoing research, room temperature and pressure superconductivity is often considered to be the holy grail of electronics engineering.

If democratized in a stable form, superconductors like this might find themselves in almost all electronics products, similar to silicone in microchips.

It is likely that TSC’s will first see high-end commercial use in Quantum Computing where their protected edge states could be used to carry quantum information.

TSC’s have shown specific promise in the field of spintronics where their unique electronic properties can be used for manipulating and controlling the flow of spin-polarized electrons for applications such as compressing and storing large amounts of data in a small area as well as other potential applications like providing an improved alternative to CMOS / solid-state devices. Applications like this are likely to reflect the mass-market applications you that you referred to.
