Integrated quantum photonics
As the field has progressed new quantum algorithms have been developed which provide short and long term routes towards the demonstration of the superiority of quantum computers over their classical counterparts. Cluster state computation is now generally accepted as the approach that will be used to develop a fully fledged quantum computer. Whilst development of quantum computer will require the synthesis of many different aspects of integrated optics, boson sampling seeks to demonstrate the power of quantum computation via technologies readily available and is therefore a very promising near term algorithm to doing so. In fact shortly after its proposal there were several small scale experimental demonstrations of the boson sampling algorithm

PQI researchers work on various aspects of quantum computing and information. Development in information theory as well as in quantum algorithms is carried out. Qubit platforms, such as superconducting microwave circuits and Majorana Fermions in semiconducting nanowires are designed for quantum computing. Quantum simulation is another approach to quantum computing; the experimental thrust is the design of a 1D solid state quantum simulation platform that can be controlled on the nanoscale, while a theoretical approach consists of the development of powerful numerical methods that would open the door to faster, more accurate simulations of various novel and exotic quantum systems on a classical computer.
