“…To the best of our knowledge, there is no third-or highorder interference experiment with fermions. However, there had been third-and higher-order interference experiments with photons [52,53]. It is an interesting topic to predict the third-and higher-order interference of fermions based on the results of photons.…”

The experimental study of the second-order interference with fermions is much less than the one with bosons since it is much more difficult to do experiments with fermions than with photons. Based on the conclusion that the behavior of two identical classical particles has exactly half fermionic and half bosonic characteristics (PRA 88, 012130 (2013)), we have studied the secondorder interference of fermions via the second-order interference of photons in Hanbury Brown-Twiss and Hong-Ou-Mandel interferometers, respectively. The experimental results are consistent with the theoretical predictions, which serve as an efficient guidance for the future interference experiments with fermions. The employed method offers an interesting and convenient way to study the coherence of fermions.

“…When the coupling strength g is greater than κ 2 and γ, the system is in the strong coupling regime [8,9]. In this regime, energy eigenstates are grouped in two-level manifolds with eigenenergies given by nωc ± g √ n (for ωa = ωc), where n is the number of energy quanta in the coupled QD-cavity system.…”

“…Following our proposal [4], we report the probing of these multi-photon transitions into the higher manifolds of the Jaynes-Cummings ladder of a strongly coupled quantum dot-photonic crystal nanocavity system [2] by measuring the third-order autocorrelation function (g (3) (τ 1 , τ 2 )) of a probe laser transmitted through such a system. Prior to this work, higherorder photon correlations had been measured for thermal [7][8][9][10] and laser [11] sources, relying on the strong excitation and high count rates available in these systems. Very recently g (3) measurements of the fluorescence from a single quantum dot weakly coupled to a microcavity were reported as well [12].…”

Nonclassical higher-order photon correlations with a quantum dot strongly coupled to a photonic-crystal nanocavity

We use the third-and fourth-order autocorrelation functions g (3) (τ1, τ2) and g (4) (τ1, τ2, τ3) to detect the non-classical character of the light transmitted through a photonic-crystal nanocavity containing a strongly-coupled quantum dot probed with a train of coherent light pulses. We contrast the value of g (3) (0, 0) with the conventionally used g (2) (0) and demonstrate that in addition to being necessary for detecting two-photon states emitted by a low-intensity source, g (3) provides a more clear indication of the non-classical character of a light source. We also present preliminary data that demonstrates bunching in the fourth-order autocorrelation function g (4) (τ1, τ2, τ3) as the first step toward detecting three-photon states.A strongly-coupled quantum dot-cavity system can produce non-classical light by filtering the input stream of photons coming from a classical coherent light source through mechanisms described as 'photon blockade' [1,2] and 'photon-induced tunneling' [2,3]. Recent proposals [4,5] have extended the concept of photon blockade from single photons to two-photon Fock state generation by coupling the probe laser to the second manifold of the Jaynes-Cummings ladder via a two-photon transition [6]. This approach can potentially be further generalized to create third-and higher-order photon states inside the cavity through multi-photon transitions to the corresponding manifold. Following our proposal [4], we report the probing of these multi-photon transitions into the higher manifolds of the Jaynes-Cummings ladder of a strongly coupled quantum dot-photonic crystal nanocavity system [2] by measuring the third-order autocorrelation function (g (3) (τ 1 , τ 2 )) of a probe laser transmitted through such a system. Prior to this work, higherorder photon correlations had been measured for thermal [7][8][9][10] and laser [11] sources, relying on the strong excitation and high count rates available in these systems. Very recently g (3) measurements of the fluorescence from a single quantum dot weakly coupled to a microcavity were reported as well [12]. However, in the low-intensity, strongly-coupled regime of cavity quantum electrodynamics, such correlations have only been measured in an atomic system [13]. Therefore, this work constitutes a significant step towards implementing a solidstate non-classical light source of photon number states.One of the benchmarks used to characterize a source of single photons is the measurement of the the second-order autocorrelation function g (2) (τ ) = a † a † (τ )a(τ )a a † a 2[14] at τ = 0, which quantifies the suppression of multi-photon * armandhr@stanford.edu † mbajcsy@uwaterloo.ca states. In actual experiments, the value of g (2) (0) for a light source is usually estimated from a Hanbury-Brown and Twiss (HBT) setup that measures coincidence counts between two single photon counting modules (SPCMs).A classical coherent light source will produce photons with Poisson statistics (g (2) (0) = 1), while a source whose output contains at most one photon a...

A novel and simple superbunching pseudothermal light source is introduced based on common instruments such as laser, lens, pinhole and groundglass. g (2) (0) = 3.66 ± 0.02 is observed in the suggested scheme by employing two rotating groundglass. Quantum and classical theories are employed to interpret the observed superbunching effect. It is predicted that g (2) (0) can reach 2 N if N rotating groundglass were employed. These results are helpful to understand the physics of superbunching. The proposed superbunching pseudothermal light may serve as a new type of light to study the second-and higher-order coherence of light and have potential application in improving the visibility of thermal light ghost imaging.
