Linear optical schemes postselect symmetric qudit Dicke states, with ancillary photons exceeding the success probability upper bound of non-ancillary schemes.
Introduces resource theories for asynchronous port-based teleportation with free classical and quantum pre-processing, computes tight fidelity bounds for isotropic, graph, and symmetrized EPR states, and proves the strongest model equals any one-way protocol in surpassing the classical teleportation
A quantum emitter in a waveguide sorts single- and two-photon light with 62% success, enabling Bell state measurements at 57% post-selected probability that exceeds the 50% linear-optics limit.
Derives explicit non-perturbative renormalization relations between bare parameters and physical observables in waveguide QED to handle IR and UV cutoffs in simulations.
Gaussian pump and quasi-phase-matching shaping in SPDC sources yields unfiltered photons with spectral purity upper bound 99.9272(6)% and two-photon interference visibilities up to 98.5(8)%.
