'''Photon antibunching''' generally refers to a light field with photons more equally spaced than a coherent laser field,<ref>Anti-bunching and Entanglement - http://www.ucd.ie/speclab/UCDSOPAMS/peoplehtml/quantumoptics2006/lecture5.pdf</ref> a signature being signals at appropriate detectors which are [[correlation and dependence|anticorrelated]]{{Clarify|date=September 2012}}. More specifically, it can (but it need not<ref>{{cite journal | last = Singh | first = S | year = 1983 | title = Antibunching, sub-poissonian photon statistics and finite bandwidth effects in resonance fluorescence | journal = Optics Communications | volume = 44 | pages = 254–258 | doi = 10.1016/0030-4018(83)90132-3 | bibcode=Singh1983254 | issue = 4}}</ref>) refer to [[sub-Poissonian]] photon statistics, that is a photon number distribution for which the variance is less than the mean. Nevertheless this kind of statistics was not observed directly with [[photon number resolving detector]]{{Citation needed|date=August 2011}}. A coherent state, as output by a laser far above threshold has [[Poisson distribution|Poissonian]] statistics yielding random photon spacing; while a [[Black-body radiation|thermal light]] field has [[super-Poissonian]] statistics and yields bunched photon spacing.  In the thermal (bunched) case, the number of fluctuations is larger than a coherent state; for an antibunched  source they are smaller.<ref>{{cite journal | last = Paul | first = H | year = 1982 | title = Photon antibunching | journal = Reviews of Modern Physics | volume = 54 | pages = 1061–1102 | doi = 10.1103/RevModPhys.54.1061 | bibcode=1982RvMP...54.1061P | issue = 4}}</ref>
 
The variance of the photon number distribution is
 
: <math>
V_n=\langle \Delta n^2\rangle=\langle n^2\rangle-\langle n\rangle^2= \left\langle \left(a^{\dagger}a\right)^2\right\rangle-\langle a^{\dagger}a\rangle ^2.
</math>
 
Using commutation relations, this can be written as
 
: <math>
V_n=\langle {a^{\dagger}}^2a^2 \rangle+\langle a^{\dagger}a\rangle-\langle a^{\dagger}a\rangle ^2.
</math>
 
This can be written as
 
: <math>
V_n-\langle n\rangle=\langle (a^\dagger)^2 a^2\rangle  -\left(\langle a^{\dagger}a\rangle\right)^2.
</math>
 
The second-order intensity correlation function (for zero delay time) is defined as
 
: <math>
g^{(2)}(0)={{\langle (a^\dagger)^2 a^2\rangle}\over{\langle a^{\dagger}a\rangle^2}}.
</math>
 
This quantity is basically the probability of detecting two simultaneous photons, normalized by the probability of detecting two photons at once for a random photon source. Here and after we assume stationary counting statistics.
 
Then we have
 
: <math>
{{1}\over{(\langle n\rangle)^2}}(V_n-\langle n\rangle) =g^{(2)}(0)-1.
</math>
 
Then we see that sub-Poisson photon statistics, one definition of photon antibunching, is given by <math>
g^{(2)}(0) < 1</math>.  We can equivalently express antibunching by <math>Q< 0</math> where the [[Mandel Q Parameter]] is defined as
 
: <math>
Q\equiv \frac{V_n}{\langle n \rangle}-1.
</math>
 
If the field had a classical stochastic process underlying it, say a positive definite probability distribution for photon number, the variance would have to be greater than or equal to the mean. This can be shown by an application of the Cauchy-Schwarz inequality to the definition of <math>g^{(2)}(0)</math>. Sub-Poissonian fields violate this, and hence are nonclassical in the sense that there can be no underlying positive definite probability distribution for photon number (or intensity).
 
Photon antibunching by this definition was first observed by [[H. Jeff Kimble|Kimble]], [[Leonard Mandel|Mandel]], and Dagenais in [[resonance fluorescence]]. A driven atom cannot emit two photons at once, and so in this case <math>g^{(2)}(0)=0.0</math>. An experiment with more precision that did not require subtraction of a background count rate was done for a single atom in an ion trap by Walther et al.
 
For historical reasons, another definition for photon antibunching is sometimes used. It can also be shown by an application of the [[Cauchy-Schwarz inequality]] to the time dependent intensity correlation function
 
: <math>
g^{(2)}(\tau)={{\langle a^{\dagger}(0)a^{\dagger}(\tau)a(\tau)a(0)\rangle}\over{\langle a^{\dagger}a\rangle^2}}.
</math>
 
It can be shown that for a classical positive definite probability distribution to exist (i.e. for the field to be classical) <math>g^{(2)}(\tau) \leq g^{(2)}(0)</math>. Hence a rise in the second order intensity correlation function at early times is also nonclassical. This initial rise is sometimes referred to as photon antibunching.
 
Another way of looking at this time dependent correlation function, inspired by quantum trajectory theory is
 
: <math>
g^{(2)}(\tau)={{\langle a^{\dagger}a\rangle_C}\over{\langle a^{\dagger}a\rangle}}
</math>
 
where
 
: <math>
\langle O \rangle_C \equiv \langle \Psi_C |O|\Psi_C\rangle.
</math>
 
with <math>|\Psi_C\rangle</math> is the state conditioned on previous detection of a photon at time <math>\tau=0</math>.
