Distilling Qubit Unitary Operations: A No-Go Theorem and Minimal Realization
Jiayi Zhao, Yu-Ao Chen, Guocheng Zhen +3
Quantum gates executed on physical hardware are inevitably degraded by environmental noise. While state purification effectively distills static quantum resources, the dynamic exec…
