Hybrid quantum-classical approach to correlated materials
Recent improvements in the control of quantum systems make it seem feasible to finally build a quantum computer within a decade. -
The half-filled Landau level: the case for Dirac composite fermions
In an external magnetic field, the energy of an electron in a two-dimensional system takes discrete values, called Landau levels. -

Direct from the 2016 Quantum Retreat in Redmond
The 2016 QRetreat took place on Microsoft’s Redmond campus on April 28 and 29, 2016. -
Conductance of a proximitized nanowire in the Coulomb blockade regime
In this paper, which was just published in Physical Review B, a quantitative theory for the two-terminal conductance of a proximitized nanowire in the Coulomb blockade regime is developed. -
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. -
Training a quantum optimizer
In this paper, published in Physical Review A, we show how to greatly improve success at solving Constraint Satisfaction Problems on a quantum computer by using a learned schedule, instead of the standard linear ramps. -
Topological Phases in InAs1−x Sbx : From Novel Topological Semimetal to Majorana Wire
In this paper, we show by computer simulations that a new material, which is a specific combination of the two semiconductors InAs and InSb (both are currently used in experimental setups on Majorana zero modes), has vastly improved properties compared to InAs or InSb alone, making it ideally suited for future devices. -
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. -
Verified compilation of space-efficient reversible circuits
Generation of reversible circuits from high-level code is an important problem in the compilation flow of quantum algorithms to lower-level hardware. -
Anomalous Fraunhofer Interference in Epitaxial Superconductor-Semiconductor Josephson Junctions
