WebSep 22, 2024 · In this paper, a controlled-phase (CPHASE) gate using the polarisation and orbital angular momentum degrees of freedom for single-photon two-qubit quantum logic is proposed. This is critical to the realisation of quantum cluster states and graph networks using transverse degrees of freedom. WebExperimentally we chose to perform our CPHASE gate with 13ns long pulses and the iSWAP-like gate with 11ns control pulses (both of which had 1ns pads on either side) as we found that shorter implementations of either gate …
