No Physics Required ! a Visual-Based Introduction to GKP Qubits for Computer Scientists

With the significance of continuous-variable quantum computing increasing thanks to the achievements of lightbased quantum hardware, making it available to learner audiences outside physics has been an important yet seldomtackled challenge. Similarly, the rising focus on fault-tolerant quantum computing has shed light on quantum error correction schemes, turning it into the locus of attention for industry and academia alike. In this paper, we explore the widely adopted framework of quantum error correction based on continuous variable systems and suggest a guide on building a self-contained learning session targeting the famous Gottesman-Kitaev-Preskill (GKP) code through its geometric intuition.
