Abstract
Example embodiments provide a reconfigurable quantum interface (RQI), preferably for quantum networking purposes. The RQI accepts input signals at numerous wavelengths and lineshapes, and converts the input signals to a number of different output wavelengths and lineshapes while retaining quantum properties (e.g., entanglements) of the signals. The RQI provides on-demand conversion to and from arbitrary input and output wavelengths and lineshapes.
Claims20
A method comprising:
- receiving a quantum input signal at a reconfigurable quantum interface, wherein the reconfigurable quantum interface includes a plurality of nonlinear media each associated with a corresponding wavelength band and at least one quantum property;
- selecting, via a switching device of the reconfigurable quantum interface, a nonlinear medium from among the plurality of nonlinear media for the quantum input signal;
- tuning the nonlinear medium to produce a quantum output signal with a desired wavelength within the corresponding wavelength band and desired one or more quantum properties;
- and
- converting, via the nonlinear medium, the quantum input signal to the quantum output signal with the desired wavelength and the desired one or more quantum properties.
