Terahertz Essential Devices Technique Research Based on Quantum Communication

Since entering 2000, with the wireless applications and technologies great fast increase, the need for spectral resource is much huge. It is becoming key point that the wireless frequency steps toward higher terahertz frequency band in the academic research aspect. The paper conducts a comparison and discussion on the properties of THz frequency band with other band; Then analyzes the essential conditions on construction quantum transmission system; Afterward, concentrates on the important devices techniques analysis for the emission and detection aspects in THz system; Later, provides the relative experimental development progress; At last, summaries a main technique and application trend of quantum transmission in coming year. All of these studies have useful academic reference value and application significance in the quantum communication field to the specialists later research.
