Geometric obstructions to quadratic time scaling in multiparameter quantum estimation
Eoin O'Connor, Jiayu He, Matteo G. A. Paris +1
Unitary encoding of a single parameter provides quadratic enhancement in precision, with the quantum Fisher information scaling quadratically with the encoding time. However, when…
Attaining Quantum Sensing Enhancement from Monitored Dissipative Time Crystals
Eoin O'Connor, Victor Montenegro, Francesco Albarelli +3
This study investigates quantum-enhanced parameter estimation through continuous monitoring in open quantum systems that exhibit a dissipative time crystal phase. We first analytic…
Bounding fidelity in quantum feedback control: theory and applications to Dicke state preparation
Eoin O'Connor, Hailan Ma, Marco G. Genoni
Achieving unit fidelity in quantum state preparation is often impossible in the presence of environmental decoherence. While continuous monitoring and feedback control can improve…
