Lü, L. Zheng, C. Ding, X. Yang] A scheme is proposed to achieve the two-mode entanglement in an asymmetric semiconductor three-coupled-quantum-well (TCQW) system based on the intersubband transitions (ISBTs). In the present scheme, the TCQW structure is trapped into a doubly resonant cavity, and the required quantum coherence effects is induced by the corresponding ISBTs, which is the key of realising entanglement. By numerically simulating the dynamics of the system, we show that the entangled cavity modes with the far-infrared wavelengh can be realised in this TCQW system. The present research provides an efficient approach to achieve far-infrared entangled light in the semiconductor nanostructures, which may have significant impact on the progress of solid-state quantum information theory.
