摘要

利用光学同差层析成像技术研究了室温下半导体异质结构中电子-空穴凝聚体辐射复合产生的超辐射脉冲的量子特性。揭示了两个相干态叠加的超辐射态的量子纠缠特征。结果表明，在一定条件下重构的维格纳函数与Schrödinger cat态的维格纳函数非常相似。

Quantum Entanglement at the Superradiance of a Condensate of Electron–Hole Pairs in Semiconductor Heterostructures

The quantum properties of superradiant pulses generated at the radiative recombination of an electron–hole condensate in semiconductor heterostructures at room temperature have been studied using optical homodyne tomography. Signatures of the quantum entanglement of superradiant states, which are superpositions of two coherent states, have been revealed. It has been demonstrated that reconstructed Wigner functions under certain conditions are very similar to the Wigner functions of the Schrödinger cat states.
