Phase transition in magic with random quantum circuits

P. Niroula, C. D. White, et al.

Discover how magic, an essential ingredient for fault-tolerant quantum computing, experiences a phase transition under coherent errors in random stabilizer codes. This groundbreaking research by Pradeep Niroula and colleagues sheds light on quantum speedup and the efficient generation of magic states.

Abstract
Magic, a crucial property for fault-tolerant quantum computing, exhibits a phase transition in random stabilizer codes subjected to coherent errors. This transition is characterized analytically, numerically, and experimentally. Below a critical error rate, syndrome measurements remove magic, offering protection; above it, they concentrate magic. This behavior sheds light on quantum speedup and efficient magic state generation.
