一维共振荧光中Wigner负态的稳态产生

Steady-state generation of Wigner negative states in 1D resonance fluorescence

Fernando Quijandría, Ingrid Strandberg, Göran Johansson

摘要:

在这项工作中,我们证明了数值的连续驱动的两能级系统(TLS)提供的非线性允许在一个空间维度的电磁场的维格纳负态的产生。维格纳负态,也就是Wigner非经典态是经典计算机范围之外的量子信息协议所需要的。聚焦于TLS的稳态发射,我们发现在相干反射消失的驱动强度处负性最大。

英文摘要:

In this work we demonstrate numerically that the nonlinearity provided by a continuously driven two-level system (TLS) allows for the generation of Wigner-negative states of the electromagnetic field confined in one spatial dimension. Wigner-negative states, a.k.a. Wigner nonclassical states, are desirable for quantum information protocols beyond the scope of classical computers. Focusing on the steady-state emission from the TLS, we find the largest negativity at the drive strength where the coherent reflection vanishes.
