摘要:

宽带单光子通常被认为不能有效地耦合到原子气体,因为在带宽的大失配。与这种直观的图像相反,在这里,我们证明了超短单光子与致密共振原子样品的相互作用深刻地修改了它们的波包模式的时间形状,而不会降低它们的非经典特性,并有效地产生零面积单光子脉冲。这是单个宽带(太赫兹级)光量子与原子之间强瞬态耦合的明显特征,具有有趣的基本含义和可能的量子信息存储的新应用。

英文摘要:

Broadband single photons are usually considered not to couple efficiently to atomic gases because of the large mismatch in bandwidth. Contrary to this intuitive picture, here we demonstrate that the interaction of ultrashort single photons with a dense resonant atomic sample deeply modifies the temporal shape of their wavepacket mode without degrading their non-classical character, and effectively generates zero-area single-photon pulses. This is a clear signature of strong transient coupling between single broadband (THz-level) light quanta and atoms, with intriguing fundamental implications and possible new applications to the storage of quantum information.
