Optimal Decoding for Measurement-Based GHZ State Preparation: The Maximum-Utility Decoder
Misha Yutushui, Theo Haas, Simon Trebst
The meticulous preparation of macroscopic Greenberger-Horne-Zeilinger (GHZ) states provides a foundational resource for quantum technologies such as metrology, cryptography, and fa…
Interaction-driven quantum phase transitions between topological and crystalline orders of electrons
André Haug, Ravi Kumar, Tomer Firon +5
Topological and crystalline orders of electrons both benefit from enhanced Coulomb interactions in partially filled Landau levels. In bilayer graphene (BLG), the competition betwee…
Theory of Next-Generation Even-Denominator States
Misha Yutushui, David F. Mross
Even-denominator quantum Hall states are leading candidates for realizing non-Abelian topological orders, with the plateau in GaAs the first and most-studied examp…
Orbitally tuned composite-fermion metal-to-superfluid transitions
Ravi Kumar, Tomer Firon, André Haug +6
The effective interaction between composite fermions, set entirely by the Coulomb potential and the underlying electronic Landau level orbitals, can stabilize exotic fractional qua…
Non-Abelian phases from the condensation of Abelian anyons
Misha Yutushui, Maria Hermanns, David F. Mross
The observed fractional quantum Hall (FQH) plateaus follow a recurring hierarchical structure that allows an understanding of complex states based on simpler ones. Condensing the e…
The numerical case for identifying paired quantum Hall phases by their daughters
Misha Yutushui, Arjun Dey, David F. Mross
Many candidate non-Abelian quantum Hall states are accompanied by nearby `daughter' states, which are proposed to identify their topological order. Combining exact diagonalization…
