Scaling Quantum Networks via Phase-Stable Vacuum Beam Guide: Architectural Blueprint and Benchmark
Yuexun Huang, Delaney Smith, Pei Zeng +4
Scaling quantum networks to continental distances requires physical infrastructure capable of overcoming both exponential attenuation and severe phase decoherence. While the concep…
Error-structure-tailored early fault-tolerant quantum computing
Pei Zeng, Guo Zheng, Qian Xu +1
Fault tolerance is widely regarded as indispensable for achieving scalable and reliable quantum computing. However, the spacetime overhead required for fault-tolerant quantum compu…
Pilot-reference-free continuous-variable quantum key distribution with efficient decoy-state analysis
Anran Jin, Xingjian Zhang, Liang Jiang +2
Continuous-variable quantum key distribution (CV QKD) using optical coherent detectors is practically favorable due to its low implementation cost, flexibility of wavelength divisi…
Dark spin-cats as biased qubits
Andreas Kruckenhauser, Ming Yuan, Han Zheng +8
We present a biased atomic qubit, universally implementable across all atomic platforms, encoded as a `spin-cat' within ground state Zeeman levels. The key characteristic of our co…
Practical hybrid PQC-QKD protocols with enhanced security and performance
Pei Zeng, Debayan Bandyopadhyay, José A. Méndez Méndez +10
Quantum resistance is vital for emerging cryptographic systems as quantum technologies continue to advance towards large-scale, fault-tolerant quantum computers. Resistance may be…
Towards efficient and secure quantum-classical communication networks
Pei Zeng, Debayan Bandyopadhyay, José A. Méndez Méndez +7
The rapid advancement of quantum technologies calls for the design and deployment of quantum-safe cryptographic protocols and communication networks. There are two primary approach…
