Technologies stemming from photonics research are omnipresent in our modern world, from laser surgery to barcode scanners and optical signals travelling through kilometers of optical fibers sending information all over the world on the internet. We are now entering a new revolution in optics. In this new era of photonics, information will be stored in the quantum states of photons – individual particles of light. Exploiting the sometimes counterintuitive properties of quantum mechanics will allow for remarkable new technologies, from the completely secure communications guaranteed by the laws of physics to a new type computer able to tackle problems that no classical computer could solve.

来自光子学研究的技术在我们的现代世界中无处不在，从激光手术到条形码扫描仪，再到通过数公里长的光纤在互联网上向世界各地发送信息的光信号。我们现在正在进入一场新的光学革命。在这个光子学的新时代，信息将存储在光子的量子态——光的单个粒子。利用量子力学有时违反直觉的特性，将会带来非凡的新技术，从物理定律保证的完全安全通信，到能够解决经典计算机无法解决的问题的新型计算机。
