“…Of particular interest for these applications are traveling wave packets prepared with a definite number of photons in a continuous temporal mode, known as continuous-mode Fock states [9][10][11][12]. As the generation of such states becomes technologically feasible [13][14][15][16][17][18][19][20][21][22][23][24] a theoretical description of the light-matter interaction [25] becomes essential, see Fig. 1.…”

We present a theoretical framework that describes a wave packet of light prepared in a state of definite photon number interacting with an arbitrary quantum system (e.g. a quantum harmonic oscillator or a multi-level atom). Within this framework we derive master equations for the system as well as for output field quantities such as quadratures and photon flux. These results are then generalized to wave packets with arbitrary spectral distribution functions. Finally, we obtain master equations and output field quantities for systems interacting with wave packets in multiple spatial and/or polarization modes.

“…The first is harnessing multi-photon interference of classical coherent states and quantum down-converted states; [10,11] by adjusting their ratio over different inherently scalable approaches, high-NOON states with up to N = 5 have been generated. The second is a bulk optic-based linear optical scheme: by manipulating polarized-encoded photons, [12][13][14][15] realistic experimental methods for generating three-and four-photon NOON states have been proposed. The third are schemes on integrated photonic circuits.…”

Maximal multi-photon entangled states, known as NOON states, play an essential role in quantum metrology. With the number of photons growing, NOON states are becoming increasingly powerful and advantageous for obtaining supersensitive and super-resolved measurements. In this paper, we propose a universal scheme for generating three- and four-photon path-entangled NOON states on a reconfigurable photonic chip via photons subtracted from pairs and detected by heralding counters. Our method is postselection free, enabling phase supersensitive measurements and sensing at the Heisenberg limit. Our NOON-state generator allows for integration of quantum light sources as well as practical and portable precision phase-related measurements.
