Developing a topological qubit 

Learn what’s involved in the journey to create a topological qubit, including different stages of development, first-of-their-kind fabrication approaches, and an overview of the many fields of knowledge that come together to make this vision a reality....Read more

APS Physical Review Letters selects Station Q paper 

  We are pleased to announce that the American Physical Society (APS) journal, Physical Review Letters, has selected the Station Q paper, Transport Signatures of Quasiparticle Poisoning in a Majorana Island, as an Editors’ Suggestion. The paper details how, working with theorists in Copenhagen, we found a way to measure the quasiparticle poisoning rate of a Majorana...Read more

Transport signatures of quasiparticle poisoning in a Majorana island 

As its name implies, the poisoning of Majorana devices by normal electrons is fatal to topological computation, so much effort is now focused on characterizing the degree of poisoning either by the creation of quasiparticle pairs within the device, or by electrons entering the device through the leads. A recent experiment (see, led by Sven...Read more

A clear view of emerging and hybridizing Majorana zero modes using epitaxial InAs-Al nanowires 

  The first signature of Majorana physics, identified experimentally at TU Delft in 2012, focused on a characteristic conductance peak at zero voltage. It bore many signatures of Majorana zero modes, but had a sizable background signal that obscured how the peak arose out of coalescing Andreev bound states. Recently, Mingtang Deng and a Station...Read more

Double semions in arbitrary dimension 

  In the paper, “Double semions in arbitrary dimension,” published in Communications in Mathematical Physics, Michael Freedman and Matthew Hastings present a new construction of topological phases of matter in higher dimensions, generalizing the double semion theory in two dimensions. This theory is distinct from the Dijkgraaf-Witten model and generalized toric code models. Read the published version....Read more
