Microsoft advances quantum computing vision and helps tackle real-world challenges 

This week marks one year since Microsoft announced our bold vision of developing a scalable, full stack quantum computing solution. During that period, we have delivered against our vision and achievement, including expanding our quantum investments across the globe and making our quantum research and technology accessible to a growing community of quantum developers....Read more

Epitaxy of advanced nanowire quantum devices 

Semiconductor nanowires are ideal for realizing various low-dimensional quantum devices. In particular, topological phases of matter hosting non-Abelian quasiparticles (such as anyons) can emerge when a semiconductor nanowire with strong spin-orbit coupling is brought into contact with a superconductor. To exploit the potential of non-Abelian anyons—which are key elements of topological quantum computing—fully, they need...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

Normal, superconducting and topological regimes of hybrid double quantum dots 

  Majorana devices will generally be much more complicated than the single-junction or single quantum dot Majorana devices that have been realized in the literature so far. (See by the Station Q team for examples of complex devices.) Recently, a first step toward complex multi-gated Majorana devices—a Majorana double quantum wire—was realized by Daniel Sherman and...Read more
