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...

Solving the quantum many-body problem with artificial neural networks 

  Working together, ETH Zurich and Microsoft QuArC researchers have provided the first application of machine-learning techniques to solve outstanding problems in quantum physics. The neural networks used in their study developed a genuine intuition of the bizarre behavior of quantum particles. For example, after the artificial intelligence is trained on the elementary rules of...

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 https://arxiv.org/abs/1612.05748), led by Sven...

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...

Triple point topological metals 

  Topological materials can yield quasiparticles that behave in a manner similar to elementary particles that are part of the standard model of particle physics. In this paper, published in Physical Review X, we report on a new class of such quasiparticles—triple point fermions—which represent fermions that have mixed properties of Dirac and Weyl fermions....

Direct from the 2016 Quantum Retreat in Redmond 

  The 2016 QRetreat took place on Microsoft’s Redmond campus on April 28 and 29, 2016. QRetreat is an annual meeting of the Station Q Santa Barbara and Station Q Redmond teams. The goals of the meeting are to update each other on the recent research in an informal atmosphere and discuss current projects. This...
