Quantum technology and quantum information is beginning to provide a different computing paradigm and quantum photonics is one of the emerging technologies in realizing quantum computers. There are a number of quantum gates which have been implemented in quantum photonics and can be used in constructing quantum circuits and realizing quantum algorithms. Here, inspired by the work done by O'Brien and his co-workers, we present a theoretical design of quantum gates in quantum photonics which by adding two excess phase shifters to a controlled quantum gate can perform arbitrary one-qubit quantum gates and then by selecting different values of control qubit, two different reconfigurable gates can be performed.
