Now is the time to assess your company's quantum readiness. Initiate internal reviews to evaluate how quantum technologies, such as Quantum Key Distribution (QKD), could enhance your current cybersecurity and communication systems. Understanding your quantum needs now will prepare you to adopt the technology as it becomes commercially viable.

How can government and policy developments benefit your quantum strategy?

Government initiatives, such as the EU Quantum Flagship and China’s quantum satellite programs, are driving the development of the quantum internet. Stay informed about these programs to identify potential partnership or co-investment opportunities. Tapping into public funding or collaborations can reduce initial costs and accelerate your company’s entry into the quantum ecosystem.

Major Obstacles to Overcome

As promising as the quantum internet is, several technical and infrastructural challenges must be addressed before it becomes a reality. How can businesses position themselves to overcome these hurdles?

How can your company prepare for the high costs of quantum hardware?

Quantum hardware, such as quantum processors and photonic circuits, remains expensive and difficult to scale. To stay ahead, consider investing in small-scale pilot projects with existing quantum technologies like Quantum Key Distribution (QKD), which is already being tested in industries like finance and telecommunications. Starting small allows your organization to build quantum expertise without massive upfront investment, while also preparing for larger-scale deployment as costs decrease over time.

What role can partnerships play in overcoming technical limitations?

Collaborating with quantum startups or academic labs can be an effective way to address the technical challenges of quantum internet, such as maintaining quantum entanglement over long distances. For example, forming a partnership with institutions like QuTech (Netherlands),  MIT’s Center for Quantum Engineering or startups focused on quantum repeaters can help your business tap into cutting-edge research while spreading the cost and risk. By collaborating with specialized experts, your organization can stay at the forefront of quantum innovation without bearing the full burden of research and development.

Should your company plan for quantum-specific infrastructure investments now?

As quantum technology evolves, businesses will eventually need to update their infrastructure to accommodate quantum communication systems. Begin by evaluating the future investments required for fiber-optic networks, laser communicationsor quantum satellite links that can handle quantum data transmission. Strategic early planning ensures that your business will not fall behind in the quantum race and will be ready to integrate these new technologies into your existing infrastructure when the time is right.

Projected Timelines: Short-Term, Medium-Term, and Long-Term Milestones

The quantum internet will not appear overnight, but developments are happening on a defined timeline. What should businesses do to prepare for the different stages of quantum internet deployment?

What quantum technologies should your company adopt in the short term?

In the next ~1-3 years, local quantum networks and Quantum Key Distribution (QKD) for secure communications will become commercially viable. Your company can start by adopting QKD for critical data exchanges and exploring local quantum networks in specific regions. Begin integrating these technologies into your cybersecurity framework, particularly if your industry handles sensitive data, such as in finance or healthcare. Early adoption of these quantum-safe technologies can strengthen your company’s reputation for security and future-proof your communications.

How can your company prepare for regional quantum networks in the medium term?

Over the next ~5 years, quantum repeaters and regional quantum networks will begin to link different metropolitan areas, expanding quantum communication capabilities. It’s essential to align your business strategy with these developments, particularly if your operations span across regions. Consider investing in quantum infrastructure partnerships and collaborating with regional hubs working on quantum technology. This ensures your business remains competitive and can take advantage of quantum-enhanced communications when they become available on a broader scale.

What should your company consider to position itself for a global quantum internet?

Over the next ~7-10 years, a global quantum internet that connects countries and continents could emerge, powered by quantum satellites and long-distance quantum repeaters. To position your business for this future, start by building a long-term quantum adoption roadmap that includes investments in quantum cybersecurity, network architecture upgrades, and global collaborations. Businesses that plan for this future now will be ready to integrate with global quantum networks and access distributed quantum computing resources, giving them a competitive edge in the decades to come.
