TQI Exclusive: Quantum Communications and Security Marketing Map

Insider Brief

• Quantum Communications and Security is one of the important fields in the rapidly emerging  quantum technology industry.
• Companies developing produces and services in this field mix quantum mechanics with the demands of modern communication and security.
• The need to protect against quantum hacks and the drive for better security in communications networks is driving the interest in Quantum Communications and Security.

Although it is barely the dawn of the quantum era, the Quantum Communications and Security field is one of the important sectors of quantum technology. Arguably, it’s the most important sector currently. Unlike other areas of the quantum field that will rely on more robust quantum computing for full implementation, the “harvest now, decrypt later” threat — a strategy where adversaries collect encrypted data today, intending to decrypt it in the future using quantum computers — creates an immediate rationale for quantum cybersecurity investments.

The development of Quantum Communications and Security technologies is being initiated by the rapid rise of quantum technologies, a field where quantum mechanics intertwines with the demands of modern communication and security. The quantum communication and security market is a complex ecosystem of innovation and competition. The Quantum Insider Intelligence Platform provides a comprehensive market map of this domain, tracking over 160 companies navigating the intricate landscape from post-quantum cryptography to the pioneering development of the quantum internet.

The quantum communication and security market can be segmented into several categories, each addressing different facets of quantum technologies and their applications in enhancing security measures against both contemporary and futuristic threats.

Post-Quantum Cryptography (PQC)

As quantum computing edges closer to becoming a practical reality, it brings with it the potential power to break the encryption that currently secures our digital world. Post-quantum cryptography represents a suite of algorithms designed to be secure against the capabilities of quantum computers. These algorithms are being developed to protect data against future threats, ensuring that the digital infrastructure remains secure even in a post-quantum era.

Quantum Communication and Security Hardware

This category includes companies that are developing the physical devices necessary for quantum communication and security. These devices include quantum key distribution (QKD) systems, quantum repeaters, and other hardware designed to harness the principles of quantum mechanics for secure communication. Unlike traditional communication systems, quantum communication exploits certain properties of quantum mechanics — such as entanglement and superposition — to create communication channels that are extremely difficult to hack. Companies in this sector are not only innovating in hardware but are also increasingly expanding their offerings to include comprehensive security suites that integrate seamlessly with existing infrastructures.

Quantum Encryption

Quantum encryption, which often includes quantum key distribution (QKD), is a method of secure communication that uses quantum mechanics to secure a communication channel. In QKD, the technology allows two parties to produce a shared random secret key known only to them, which can then be used to encrypt and decrypt messages. What makes quantum encryption stand out is its ability to detect any eavesdropping attempt. If an eavesdropper tries to intercept the quantum keys being exchanged, the keys are altered in such a way that both the sender and the receiver are alerted to the presence of the eavesdropper. Companies specializing in quantum encryption are developing solutions that promise to elevate the security of data transmission to unprecedented levels.

Quantum Internet

The concept of a quantum internet represents the next frontier in the evolution of communication networks. It envisions a globally interconnected network of quantum computers, devices, and users that leverage quantum phenomena to achieve ultra-secure communication and exponentially faster information processing capabilities. Developing the quantum internet refers to the creation of robust and secure quantum networks. Developers of these networks are often concerned with ensuring compatibility with existing internet infrastructure to pave the way for quicker adoption.

Companies working in this domain are pioneering technologies that could one day enable instant, secure communication across the globe, which would lead to a revolution in how people interact with the digital world.

Note on Limitations

The intersection of quantum computing and cybersecurity is blurring the lines between traditional categorizations. Companies may simultaneously operate in multiple segments, offering both hardware solutions and advanced cryptographic algorithms. This convergence reflects the multidisciplinary nature of the field, where breakthroughs in quantum mechanics could also influence the development of secure communication technologies.

On that point, quantum security and communications is the focus of active research — and  challenges, timelines and current technological readiness are all under question in this evolving field.

Navigating the quantum communication and security market requires a nuanced understanding of both the technological landscape, the strategic ambitions of key players and an understanding of how research could affect timelines and roadmaps.

The Quantum Insider Intelligence Platform serves as a resource, offering in-depth insights into funding, partnerships, and technology developments. As we stand on the brink of a quantum era, the race to secure the digital future is more intense than ever, with implications that extend far beyond the confines of the tech industry.
