Clifford-deformed zero-rate LDPC codes with 50% biased noise thresholds
Jagannath Das, Sayandip Dhara, Pedro Medina +2
Applying single-qubit Clifford unitaries to a Pauli stabilizer code produces a Clifford-deformed variant whose stabilizers remain Pauli operators, but with locally rotated Pauli ax…

Microscopic theory of field-tuned topological transitions in the Kitaev honeycomb model
Jagannath Das, Aman Kumar, Vikram Tripathi
We microscopically construct an abelian mutual Chern-Simons lattice gauge theory for magnetic field-tuned topological transitions in the Kitaev model and obtain a complete characte…

Field tuning Kitaev systems for spin fractionalization and topological order
Jagannath Das, Sarbajaya Kundu, Aman Kumar +1
The honeycomb Kitaev model describes a spin liquid with topological order and fractionalized excitations consisting of gapped -fluxes and free Majorana fermions. Competin…
