Quantum Optics is a field of physics that studies light and matter interaction from the macroscopic level down to a single atom and from high intensity lasers down to a single photon. Quantum Optics, like other branches of science, started as a passive study of natural phenomenon, however it quickly evolved into manipulating the states of light and matter in order to produce desirable outcomes. This evolution made Quantum Optics the leading candidate for introducing quantum physics based applications in the next few decades.
Quantum mechanics plays an important role in every aspect of modern human life. For example, with the development of internet and computer science, quantum theory has inspired a number of new technologies and new ideas. In communication networks, electrons are being replaced by photons and cables are being replaced by optical fibers and sometime free space. Having this in mind, it is expected that, over time, classical applications will be rendered obsolete by their quantum counterpart. The quantum optics scientific society is well on its way toward producing end user applications in many fields like quantum communication and cryptography, bio-sensing, and many more. Not to mention that applications in quantum encryption, a sub-field of Quantum Optics, are already in the market.
Together with our collaborators at the Institute for Quantum Science and Engineering, Texas A&M University, we investigate the interaction between atoms and photons at the single-particle level where we exploit quantum mechanical properties in order to to manipulate information and observe phenomena that are not allowed in the classical world.
The measurement of small distances is a fundamental problem since the early days of science
