Research Summary

Franco Nori (Ph.D.)

Our research group performs interdisciplinary studies at the interface between nanoscience, quantum computing, quantum information processing, superconducting quantum circuitry for quantum computing, photonics, quantum optics, atomic physics, nano-mechanics, mesoscopics, computational physics, and condensed matter physics.

We are developing the QuTiP software used worldwide for quantum information processing, quantum optics, and quantum open systems. We are also using techniques from AI and Machine Learning to solve computationally hard problems. We are also studying the Coherent Ising Machine and fast computing using networks of Optical Parametric Oscillators. The Web of Science has listed our research work as Highly Cited for 2017-18-19-20.

We have published more than 30 papers in collaboration with various companies (NEC, Hitachi, Toshiba, NTT, IBM, etc.). Currently, we are conducting long-term joint research with NTT Research laboratories with the goal of solving difficult computational problems.
