概要	Surface Code is a two-dimensional topological quantum error-correcting code that protects quantum information through geometric redundancy. Introduced by Alexei Kitaev in 2003, surface code is considered the leading candidate for large-scale fault-tolerant quantum computing due to its high error thresholds and feasibility on two-dimensional qubit arrays.	Quantum Teleportation is a protocol for transferring an unknown quantum state between distant parties using entanglement and classical communication. Discovered by Bennett et al. in 1993, teleportation violates no fundamental principles but demonstrates the power of entanglement: an unknown quantum state can be reconstructed at a distant location without ever being transmitted.
