We discuss an approach to the problem of creating a photon-number-resolving detector using the giant Kerr nonlinearities available in electromagnetically induced transparency. Our scheme can implement a photon-number quantum-nondemolition measurement with high efficiency $(\ensuremath{\sim}99%)$ using fewer than 1600 atoms embedded in a dielectric waveguide.

Colloquium: Strongly interacting photons in one-dimensional continuum (2016, background): “The cross-Kerr effect has been studied extensively in the past as a possible route to, e.g, quantum nondemolition measurements (QND) of single photons (Munro et al., 2005) and photonic gates (Milburn, 1989; Turchette et al., 1995).”
Linear optical quantum computing with photonic qubits (2005, methodology): “Several schemes for single-photon QND measurements have been proposed, either with linear optics (Howell and Yeazell 2000a; Kok et al. 2002), optical quantum relays (Jacobs et al. 2002), or other implementations (Brune et al. 1990; Brune et al. 1992; Roch et al. 1997; Munro et al. 2005).”
