Topological phases of matter have captured our imagination over the past few years, with tantalizing properties such as robust edge modes and exotic non-Abelian excitations, and potential…
Entangled photon pairs from semiconductor quantum dots.

Tomographic analysis demonstrates that the polarization state of pairs of photons emitted from a biexciton decay cascade becomes entangled when spectral filtering is applied and that the remanent information in the quantum dot degrees of freedom is negligible.
Anomalous Floquet-Anderson Insulator as a Nonadiabatic Quantized Charge Pump
- P. Titum, E. Berg, M. Rudner, G. Refael, N. Lindner

We show that two-dimensional periodically driven quantum systems with spatial disorder admit a unique topological phase, which we call the anomalous Floquet-Anderson insulator (AFAI). The AFAI is…
Photocurrents in Weyl semimetals

The generation of photocurrent in an ideal two-dimensional Dirac spectrum is symmetry forbidden. In sharp contrast, we show that three-dimensional Weyl semimetals can generically support significant…
Fractionalizing Majorana fermions: non-abelian statistics on the edges of abelian quantum Hall states
- N. Lindner, E. Berg, G. Refael, A. Stern
- Physics
- 25 April 2012
We study the non-abelian statistics characterizing systems where counter-propagating gapless modes on the edges of fractional quantum Hall states are gapped by proximity-coupling to superconductors…
Universal transport signatures of Majorana fermions in superconductor-Luttinger liquid junctions

One of the most promising proposals for engineering topological superconductivity and Majorana fermions employs a spin-orbit coupled nanowire subjected to a magnetic field and proximate to an s-wave…
Deterministic generation of a cluster state of entangled photons
- I. Schwartz, D. Cogan, D. Gershoni
- PhysicsScience
- 23 June 2016
This work uses semiconductor quantum dots to deterministically generate long strings of polarization-entangled photons in a cluster state by periodic timed excitation of a precessing matter qubit, and produces strings of hundreds of photons in which the entanglement persists over five sequential photons.
Optical skyrmion lattice in evanescent electromagnetic fields

- PhysicsScience
- 30 May 2018
It is shown that optical skyrmion lattices can be generated using evanescent electromagnetic fields and demonstrated using surface plasmon polaritons, imaged by phase-resolved near-field optical microscopy and shown how the optical sk Kyrmions lattice exhibits robustness to imperfections while the topological domain walls in the lattice can be continuously tuned.
Proposal for pulsed on-demand sources of photonic cluster state strings.
- N. Lindner, T. Rudolph
- PhysicsPhysical Review Letters
- 8 September 2009
Using realistic parameters for current quantum dot sources, it is concluded high entangled-photon emission rates are achievable, with Pauli-error rates per photon of less than 0.2%.
