Quantum photonics enabling novel quantum computer applications

Quantum photonics allows for a variety of quantum information applications. Here I will present that the exploit of quantum photonics allows for enhanced data security for quantum and classical computers. The latter is based on feasible hybrid classical-quantum technology, which shows promising new applications of readily available quantum photonics technology for complex data processing. I will also show how optical quantum computers allow for novel architectures that rely on superimposed order of quantum gates. As outlook I will discuss technological challenges for the scale up of photonic quantum computers, and our group’s current work for addressing some of those.
