Characterizing Vacuum Beam Guide for Photonic Quantum Applications

ORAL

Abstract

The proposed vacuum beam guide (VBG) represents an innovation in the field of photonic channel technology, guaranteeing an ultra-low level of attenuation and a broad transmission linewidth, which offers an unprecedented quantum capacity exceeding Tera-qubits per second on a continental scale. However, its stability in terms of interferometry remains unexamined. To address this gap, we have developed a comprehensive error model that captures the intrinsic phase noise power spectral density associated with VBG, thereby revealing the advantages of VBG for interferometry over existing techniques. This model facilitates a comprehensive characterization of VBG as a photonic quantum channel, thereby facilitating a detailed investigation of its transformative potential. Our theoretical analysis demonstrates the feasibility of VBG and its expected performance in a wide range of quantum applications.
