quantum counter 用来标志在一定的光谱范围(例如罗丹明6G浓溶液的光谱范围为300至600nm)内发射时的量子产率与激发能无关的介质。也用于在介质中所产生的电信号和光子通量成正比的器件之中。
如果量子密码开始工作,这样的光子计数器是必不可少的,因为这样一来将可以使用量子中继器。
Such a photon counter is essential if quantum cryptography is to work, because it will allow what are known as quantum Repeaters to be built.
文中介绍了气体电离探测器,固体、气体闪烁计数器,半导体探测器以及量子微量热器等方面的国外近年进展简况。
