The May 2026 arXiv preprint (abs/2605.20329) proposes that a superconducting circular current in a semiconductor LED structure imprints its macroscopic phase winding onto recombining electron-hole pairs, producing photon pairs carrying opposite orbital angular momentum. Using Ginzburg-Landau theory for the supercurrent and BCS theory for pairing, the authors show that the emitted two-photon state is entangled in OAM and can inherit coherent superpositions from a superconducting qubit. This is a preprint, not yet peer-reviewed, with no experimental data or sample size; the work is entirely numerical and analytical. Related experimental demonstrations of OAM-entangled photons have so far relied on bulky spontaneous parametric down-conversion in bulk crystals or integrated silicon waveguides (Wang et al., Science 2018), while superconducting LEDs have been realized in NbN/InGaAs heterostructures but without engineered angular momentum (Hayat et al., Phys. Rev. B 2022). The arXiv paper correctly identifies the phase-inheritance mechanism yet underplays decoherence from vortex motion and interface disorder, factors that real hybrid devices have shown to limit coherence times to nanoseconds. It also overlooks the challenge of out-coupling high-OAM modes into single-mode fibers without mode sorters that introduce loss. If validated, the platform could close the gap between superconducting processors and photonic networks by mapping qubit states directly to flying OAM qubits, but experimental realization will require cryogenic integrated photonics that current fabrication yields do not yet support.
