Current research

My current research emcompasses the field of quantum nonlinear optics, quantum networks, hybrid systems and quantum computation with photons. I am trying to find novel methods and systems for generating strong nonlinearity at quantum levels. The aim is to harness the nonlinearity for achieving efficient photon-photon interaction at the quantum level - the holy grail of both nonlinear optics at and implementation of photonic logic gates for quantum information protocols. Furthermore, I investigate hybrid semiconductor-superconductor systems for developing efficient light-matter interfaces. Such interfaces has potential applications in quantum technologies like quantum nodes, memories and optical switches. I also work on engineering of decoherence for efficient generation and preservation entanglement - a key requirement for quantum information and computation.
