Quantum computing over the rainbow*

In this talk, I will present how the quantum version of the optical frequency comb can be used as a universal quantum computing platform. This quantum optical frequency comb is not emitted by a laser (as is usually the case for the classical OFC) but by an optical parametric oscillator whose two-photon emission provides the basic entanglement mechanism for quantum computing. Also, in this implementation, qubits are replaced with quantum optical fields, a.k.a. qumodes. I will review progress by research groups around the world, which includes current record qumode scalability over all qubit platforms.
