光子计数攀登Jaynes-Cummings阶梯

Climbing the Jaynes-Cummings ladder by photon counting

Fabrice P. Laussy, Elena del Valle, Michael Schrapp, Arne Laucht, Jonathan J. Finley

摘要:

我们提出了一种新的方法来观察强耗散腔量子电动力学系统中Jaynes-Cummings非线性的直接实验证据,其中大损耗与强光-物质相互作用竞争。这是一个非常热门的问题,特别是对于微腔中的量子点,其中从Jaynes-Cummings阶梯的更高梯级的过渡仍有待明确证明。我们比较了系统的相干和非相干激发,发现失谐发射器的共振激发使得在目前可用的实验系统中可以明确地证明很少的光子量子非线性。

英文摘要:

We present a new method to observe direct experimental evidence of Jaynes--Cummings nonlinearities in a strongly dissipative cavity quantum electrodynamics system, where large losses compete with the strong light-matter interaction. This is a highly topical problem, particularly for quantum dots in microcavities where transitions from higher rungs of the Jaynes--Cummings ladder remain to be evidenced explicitly. We compare coherent and incoherent excitations of the system and find that resonant excitation of the detuned emitter make it possible to unambiguously evidence few photon quantum nonlinearities in currently available experimental systems.
