摘要:

测量由两个统计上独立的热光源发射的光的$M$阶强度关联函数可以显示任意阶$N = M/2$的类N00N干涉。我们表明,通过一个特定的选择检测器的位置,可以隔离$M$光子量子路径,无论是所有的$M$光子从同一个源或$M/2$光子共同发射的两个源。后一种叠加显示了具有$N = M/2$的类N00N振荡,其可以用于,例如,在天文学中,以$M/2$倍增加的分辨率成像两个遥远的热源。我们还讨论了略有修改的检测方案,提高了可见性的N00N样的干涉图案和目前的测量验证理论预测。

英文摘要:

Measuring the $M$th-order intensity correlation function of light emitted by two statistically independent thermal light sources may display N00N-like interferences of arbitrary order $N = M/2$. We show that via a particular choice of detector positions one can isolate $M$-photon quantum paths where either all $M$ photons are emitted from the same source or $M/2$ photons are collectively emitted by both sources. The latter superposition displays N00N-like oscillations with $N = M/2$ which may serve, e.g., in astronomy, for imaging two distant thermal sources with $M/2$-fold increased resolution. We also discuss slightly modified detection schemes improving the visibility of the N00N-like interference pattern and present measurements verifying the theoretical predictions.
