Programmable Photonics Using Dynamically Modulated Coupled Resonances

We introduce the platform for photonic computation using dynamically modulated coupled resonances. By realizing the interference between the couplings with tunable gauge fields, we implement reconfigurable and universal SU(2) time gates, which are the unit elements for achieving universal U(<tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$N$</tex>) operations in an adaptable manner. In the talk, the application of the proposed platform to quantum gates and quantum-optical analogy as examples.
