Abstract
A photonic integrated circuit comprising one or more waveguides comprising a second order non-linearity configured to operate on optical pulses each having a pulse length shorter than 1000 optical cycles, as measured at their full width at half maximum. The circuit is configured to generate one or more quantum states carried by one or more of the optical pulses, manipulate one or more of the quantum states, and/or measure one or more of the quantum states.
Claims22
A photonic integrated circuit, comprising:
- one or more waveguides comprising a second order non-linearity configured to operate on classical and/or quantum optical pulses each having a pulse length shorter than 1000 optical cycles, as measured at their full width at half maximum of their classical field values or their quantum wave functions, so as to at least:
- generate one or more quantum states carried by one or more of the optical pulses,
- manipulate one or more of the quantum states, or
- measure one or more of the quantum states;
- and
- wherein the waveguides comprise at least an optical parametric amplifier (OPA) comprising a phase-matching and/or a dispersion engineering for a second order parametric amplification process involving a signal vacuum field and at least one of the optical pulses comprising a first pump pulse.
