Quantum metrology with quantum-chaotic sensors

Quantum metrology with quantum-chaotic sensors

Enhanced sensing using quantum systems generally relies on preparation of highly non-classical states, such as entangled or squeezed states. Here the authors propose a different approach, based on hypersensitivity of quantum-chaotic dynamics with respect to parameters of the system.
