Quantum limits to polarization measurement of classical light
Marcin Jarzyna
Polarization of light is one of the fundamental concepts in optics. There are many ways to measure and characterise this feature of light but at the fundamental level it is quantum…
Parameter estimation in the presence of the most general Gaussian dissipative reservoir
Marcin Jarzyna, Marcin Zwierz
We analyze the performance of quantum parameter estimation in the presence of the most general Gaussian dissipative reservoir. We derive lower bounds on the precision of phase esti…
Incoherent on-off keying with classical and non-classical light
Marcin Jarzyna, Piotr Kuszaj, Konrad Banaszek
We analyze the performance of on-off keying (OOK) and its restricted version pulse position modulation (PPM) over a lossy narrowband optical channel under the constraint of a low a…
True precision limits in quantum metrology
Marcin Jarzyna, Rafal Demkowicz-Dobrzanski
We show that quantification of the performance of quantum-enhanced measurement schemes based on the concept of quantum Fisher information yields asymptotically equivalent results a…
