A planar lightwave circuit for adjusting qubit frequency, the circuit comprising:
- a plurality of laser discharge structures located on the planar lightwave circuit, wherein a position of each of the plurality of laser discharge structures on the planar lightwave circuit corresponds with a position of each of a plurality of qubits on a chip;
- and
- a single laser source connected to each of the plurality of laser discharge structures by one or more Mach Zehnder switches and a plurality of optical connections.
A structure comprising:
- a plurality of laser discharge structures located on a planar lightwave circuit, wherein a position of each of the plurality of laser discharge structures on the planar lightwave circuit corresponds with a position of each of a plurality of qubits on a chip;
- and
- a single laser source connected to each of the plurality of laser discharge structures by one or more Mach Zehnder switches and a plurality of optical connections, wherein the single laser source is connected to an input of a single Mach Zehnder switch by a mode converter and one of the plurality of optical connections.
