We describe an experimental implementation to generate and measure high-dimensional, time-bin entangled qudits. Two-photon time-bin entanglement is generated via spontaneous four-wave mixing in single-mode fiber. Unbalanced Mach-Zehnder interferometers transform selected time-bins to polarization entanglement, allowing standard polarization-projective measurements to be used for complete quantum state tomographic reconstruction. Here, we generate maximally entangled qubits (d = 2), qutrits (d = 3), and ququarts (d = 4), as well as other phase-modulated non-maximally entangled qubits and qutrits. We reconstruct and verify all generated states using maximum likelihood estimation tomography.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
