Magic State Distillation via Codes over Binary Extension Fields
Anqi Gong, Christopher A. Pattison, Patrick Rall +1
Fault-tolerant quantum computation architectures are frequently bottlenecked by the overhead of producing high-fidelity magic states. In this work, we use algebraic geometric techn…
Entangling logical qubits without physical operations
Jin Ming Koh, Anqi Gong, Andrei C. Diaconu +6
Fault-tolerant logical entangling gates are essential for scalable quantum computing, but are limited by the error rates and overheads of physical two-qubit gates and measurements.…
Decoding quantum low density parity check codes with diffusion
Zejun Liu, Anqi Gong, Bryan K. Clark
An efficient decoder is essential for quantum error correction, and data-driven neural decoders have emerged as promising, flexible solutions. Here, we introduce a diffusion model…
Computation with quantum Reed-Muller codes and their mapping onto 2D atom arrays
Anqi Gong, Joseph M. Renes
We give a fault tolerant construction for error correction and computation using two punctured quantum Reed-Muller (PQRM) codes. In particular, we consider the self-…
Toward Low-latency Iterative Decoding of QLDPC Codes Under Circuit-Level Noise
Anqi Gong, Sebastian Cammerer, Joseph M. Renes
We introduce a sliding window decoder based on belief propagation (BP) with guided decimation for the purposes of decoding quantum low-density parity-check codes in the presence of…
