Error Correction in Quantum Chips

Recent advancements in quantum computing have converged on error correction as the critical path to practical, fault-tolerant systems. Three distinct architectural paradigms—Google’s transmon-based surface codes, Amazon’s bosonic cat qubits, and Microsoft’s topological Majorana qubits—represent divergent strategies to mitigate errors while balancing scalability, hardware overhead, and physical qubit reliability. In this blog post you will find technical details, experimental progress, and trade-offs across these approaches.
