Entanglement and encoding in discrete frequency bins – a quantum analogue of wavelength-division multiplexing – represents a relatively new degree of freedom for quantum information with photons. Potential advantages include generation of high-dimensional units of quantum information called qudits, which can carry multiple qubits per photon; robust transmission over fiber; frequency parallelism and routing; and compatibility with on-chip implementations, as well as hyperentanglement with other photonic degrees of freedom. In this talk I first give an overview of manipulating and measuring quantum states encoded and entangled in the photonic frequency degree of freedom. I will then discuss our recent experiments that focus on high-dimensional entanglement and mixing of multiple frequency bins in a single operation, going well beyond nearest neighbor “interactions.
