Quantum Error Correction: Essential for Scaling
Quantum error correction is a critical technology for the development of large-scale quantum computers. It addresses the challenges posed by the susceptibility of individual qubits to environmental noise, which can disrupt quantum information. By using multiple physical qubits to create a single logical qubit, researchers can enhance the stability and reliability of quantum computations. The principle of redundancy in classical engineering is applied here, where increasing the array of physical qubits leads to significant error reduction in logical qubits.
