QdcEm: Quantum Data Center Emulator

A hardware-compatible framework for emulating Quantum Data Centers on single-chip superconducting quantum processors.

This open-source project provides the complete implementation supporting the paper:

“A Framework for Quantum Data Center Emulation Using Digital Quantum Computers” — S. N. Elyasi, P. Monti, J. Li, R. Lin — arXiv:2509.04029 (2025)

QdcEm partitions a real quantum processor’s coupling map into virtual Quantum Processing Units (QPUs) and introduces an experimentally grounded Collisional Model (CM) to emulate optical quantum communication channel noise — transducers and fiber segments — with tunable, physically motivated parameters. The result is a self-contained emulation environment for distributed quantum computing that runs entirely within a single chip.

QdcEm includes hardware-compatible implementations for:

Remote gate protocols (Cat-State Communication and Teleportation) across virtual QPU boundaries,
CM-based noise injection for transducer-induced and fiber-induced decoherence,
Distributed quantum algorithms — Bell-state generation, Grover’s Search, and the Quantum Fourier Transform, and
All plotting scripts to recreate the figures from the paper.
