GKP-Based Photonic Quantum Computing: Challenges and Classical Simulation Approaches

Gottesman-Kitaev-Preskill (GKP) states provide a promising route to fault-tolerant photonic quantum computing. In this talk, I will give a brief overview of GKP-based photonic quantum computing, highlighting its advantages and limitations. I will then discuss the challenges associated with classical simulations of multi-mode photonic systems and propose a potential solution to address these difficulties.
