Introduction
In recent headlines, Nvidia CEO Jensen Huang and Meta CEO Mark Zuckerberg have both been vocal about the escalating race in quantum computing. Some of these comments generated price fluctuations for publicly traded company stocks in this space, but the real news is the urgent call regarding the foundation of our current digital security infrastructure. Quantum computing poses a direct threat to traditional public key exchange algorithms like RSA, Diffie-Hellman, and Elliptic Curve Cryptography (ECC), which are crucial to securing everything from corporate emails to financial transactions and critical infrastructure like water and power systems.
The threat’s immediacy cannot be overstated. Even if quantum computers capable of breaking these algorithms aren’t available today, the threat of “Harvest Now, Decrypt Later” attacks is present now. It is very likely that bad actors, including nation-states, are already collecting encrypted data, banking on future quantum capabilities to decrypt this information resulting in compromises of long-term data confidentiality and security.
However, it’s not all doom and gloom. Quantum technology and science also promises a new era of security through quantum entanglement, with the ability to provide security levels that are currently unattainable with classical security systems. This “physics-based” security is unbreakable by any amount of computing power, now or in the future! The duality of threat and opportunity sets the stage for a significant transformation in how organizations approach cybersecurity.

Securely Connecting Data Centers and Beyond Using Entanglement
The backbone of our digital world, data centers, are at the heart of this quantum revolution. These hubs process, store, and transmit data critical for streaming, AI computation, and vast enterprise applications. Traditionally, optical fiber transports classical networking traffic, but quantum networks could redefine the security for this data, voice, and video transfer.
Quantum networks are able to secure connections between primary, secondary, and disaster recovery sites, making them immune to traditional forms of data interception. Even within a localized setting, an entanglement-based quantum network could offer provably secure communications, which can then be expanded to create metro or even wide-area networks, using both terrestrial and non-terrestrial links.
Investment, Issues, and Current Projects
Quantum computing has seen substantial investment, with billions poured into research and development. According to recent market analyses, the total addressable market for quantum technologies is projected to reach $100 billion by 2040. One critical aspect often overlooked in discussions about quantum computing is the need to implement sophisticated quantum networks to scale these systems. In the same way that GPUs and CPUs are networked to create supercomputers, quantum computers can be interconnected to share qubits, thereby reducing the reliance on the capacity and limitations of a single quantum machine.
This networking is not just theoretical. Initiatives like those at the United States Air Force Research Laboratory are actively exploring how to simulate, test, and operate entanglement-based quantum network infrastructure, including the networking of quantum computers with different qubit technologies.
Energy Efficiency and Quantum Advantage
The energy consumption of data centers, particularly with the AI boom, is a growing concern. Quantum computing could potentially offer a more energy-efficient solution for certain practical computational tasks, especially those involving complex simulations or exponential scaling problems. For instance, quantum algorithms could dramatically reduce the energy and time required for training AI models, making the process not only faster but also more environmentally friendly.
Deployment Strategies
For organizations looking to start small, deploying a local quantum network can secure intra-campus communications. This can be scaled up by integrating these local networks with others through classical or quantum means, eventually forming robust, secure quantum communication networks across larger areas.

Are You Ready for Prime Time?
Quantum Key Distribution (QKD) was one of the first practical applications of quantum networking, focusing on a single purpose. However, the real potential of quantum networking extends far beyond QKD. It offers a platform for multiple secure qubit-based applications while leveraging the unique properties of quantum mechanics for unprecedented security.
Conclusion
The quantum computing era is upon us, and while the exact timeline for its disruptive impact remains uncertain, preparation is paramount. Organizations must begin to rethink security architectures, investing in research, understanding quantum threats, and exploring quantum opportunities. The transition might not be immediate, but the groundwork laid today will determine who leads in the quantum era of tomorrow. Whether it’s through adopting quantum-safe cryptography or exploring quantum networking, the time to act is now, ensuring that when quantum computing does hit its stride, your organization is not just ready but ahead of the curve.
