Abstract
A topologically-protected traveling-wave amplifier includes resonators arranged in a two-dimensional array defining a periphery including a first edge. An output line is coupled to an output resonator disposed along the first edge spaced from an input resonator coupled to an output line. A synthetic gauge field generator associated with the resonators provides a topologically-protected edge state corresponding to propagation along the periphery in a propagation direction from the input resonator along the first edge to the output resonator. A parametric driving element creates pairs of photons in the edge state and amplifies a signal propagating along the first edge in the propagation direction. A signal incident from the input line propagates in the propagation direction along the first edge while being amplified and is detected at the output line as an amplified signal. A signal incident from the output line is attenuated before emerging at the input resonator.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
