July 2025 A groundbreaking advancement is reshaping the future of cybersecurity and network infrastructure: the Quantum Entanglement-Based Secure Routing Protocol for Networks, filed under U.S. Provisional Patent No. 63/706,491. This innovative protocol harnesses the power of quantum entanglement to create a fundamentally secure and intelligent framework for routing data across networks, transcending the limitations of classical cryptographic methods.
Current routing protocols—despite the use of strong encryption—are susceptible to an increasing array of cyber threats, especially in the emerging era of quantum computing. Risks such as man-in-the-middle attacks, data injection, and compromised routing tables present real challenges to the integrity and confidentiality of network communications. These threats are particularly acute in critical sectors such as defense, finance, healthcare, and national infrastructure.
The newly proposed protocol introduces a paradigm shift by embedding quantum entanglement mechanisms directly into routing decisions and security checks. The core features include:
Entangled Quantum Key Synchronization: Nodes exchange entangled photon pairs, allowing synchronized authentication and routing decisions immune to classical interception.
Quantum Score Routing Metric: Routing paths are chosen based on quantum fidelity scores—dynamic metrics that reflect the health and trust of quantum links.
Tamper-Evident Packet Forwarding: Quantum state collapse monitoring ensures that any unauthorized interception or modification of packets is immediately detected.
This strategy supersedes weak trust assumptions with quantum verifiability, providing proactive defensive capabilities instead of reactive containment.
The architecture includes hybrid classical-quantum quantum processor- and memory-equipped nodes with SDN-based control planes. Each node maintains its Quantum Entanglement Record Table (QERT), which contains information related to fidelity, path history, and entanglement status. After successful quantum handshake-check validations, are the packets routed?
Prototype development leverages:
Qiskit will simulate quantum entanglement and fidelity checks.
Mininet to model software-defined network (SDN) packet flows.
Path decision algorithms influenced by real-time quantum state metrics.
Preliminary results show:
Improved detection of injection and spoofing attempts.
Enhanced packet delivery reliability through dynamic quantum-aware routing.
Effective mitigation of distributed denial-of-service (DDoS) attacks using entanglement-based flow redirection.
This secure routing protocol could bring changes to various fields:
Defense and military networks
Global banking and fintech infrastructures
Secure cloud and healthcare information systems
Critical energy and transportation systems
It supports the worldwide movement into post-quantum cryptography and zero-trust architectures as a quantum-native alternative to conventional defense protocols.
This is an important development toward the Quantum Internet, where entangled nodes offer the most secure communications across global networks. As the quantum hardware ecosystem evolves with quantum repeaters, photonic chips, and space-based entanglement distribution all in existence, this protocol offers a practically scalable base to actually implement.
With U.S. Provisional Patent No. 63/706,491 establishing a new frontier in network security, how should enterprises and governments begin adopting quantum-enhanced routing technologies? What are the biggest technical and policy hurdles to deploying entanglement-based infrastructure?
