    How does quantum error correction help maintain stable logical qubits during noisy computations?

    Asked on Saturday, Oct 11, 2025

    Quantum error correction is essential for maintaining stable logical qubits by encoding them into multiple physical qubits, allowing the system to detect and correct errors without measuring the quant…
