Quantum metrology of two-photon absorption
Carlos Sánchez Muñoz, Gaetano Frascella, Frank Schlawin
We consider the measurement of two-photon absorption (TPA) cross sections as a quantum metrology problem. We establish the scaling behaviour of nonclassical light sources for precision measurements of TPA cross sections and assess different measurement strategies. Finally, the impact of single-photon losses is discussed.
