Abstract: Disclosed herein is a topologically protected π/8-gate which becomes universal when combined with the gates available through quasi-particle braiding and planar quasi- particle interferometry. A twisted interferometer, and a planar π/8-gate in CTS, implemented with the help of the twisted interferometer, are disclosed. Embodiments are described in the context of state X (CTS) supported by an ISH, although the concept of a twisted- interferometer is more general and has relevance to all anionic, i.e. quasiparticle systems.

Abstract: A fusion outcome quasiparticle may be trapped in a potential well of a topological segment. The fusion outcome quasiparticle may be the product of fusion of a first quasiparticle and a second quasiparticle, where the first and the second quasiparticles are localized at ends of a topological segment. The potential well having the fusion outcome quasiparticle trapped therein and a third quasiparticle may be moved relative to each other such that the potential well and the third quasiparticle are brought toward each other. The quasiparticles may be Majorana modes of a nanowire.
