What Are the Challenges in Quantum Feedback Control?
One of the primary challenges in quantum feedback control is the measurement problem. Quantum measurements can collapse the wavefunction, leading to loss of coherence and altered system states. Designing non-invasive measurements that provide accurate information without significantly disturbing the system is a complex task. Another challenge is the need for fast and efficient computational methods to process measurement data and generate feedback in real-time. Additionally, noise and decoherence from the environment can significantly affect the performance of quantum feedback control systems, necessitating advanced error-correction techniques.
