Passive Pauli Toggling of Polarization Qubits in Optical Fibers: Error Bounds and QKD Performance
Bongjune Kim, Jeongho Bang
Polarization qubits offer a direct route to fiber-based quantum communication, yet the fiber that carries them also scrambles their reference frame through uncontrolled birefringen…

Universality cost of non-Gaussian enhancement in continuous-variable quantum teleportation: A fidelity--deviation trade-off
Kyoungho Cho, Bongjune Kim, Jeongho Bang
Continuous-variable (CV) quantum teleportation is usually benchmarked by average fidelity, but when the teleportation is repeatedly used within optical networks or measurement-base…
