MDI QKD — Quantum Communication for Modern Digital Connectivity
As global communication expands and security threats evolve, secure information exchange over the internet has become paramount. The answer is Quantum-Secure Networking powered by Quantum Key Distribution.
Measurement-Device-Independent Quantum Key Distribution (MDI QKD) takes this a step further by removing the most vulnerable part of traditional systems, the detectors. It enables secure key exchange even if the measurement devices are compromised, making quantum networks more secure and scalable.
MDI QKD is a major step forward in building secure, scalable, and trustworthy quantum communication networks, essential for the future of digital connectivity.
Navigating the Quantum Threat together with QKD
Quantum Key Distribution (QKD) brings a groundbreaking level of security to digital communications, harnessing quantum mechanics to create virtually unbreakable encryption. Quantum communication holds the potential to transform information and communication technologies (ICTs), positioning itself as a fundamental technology for the future digital economy and society.
Unmatched Security
Quantum Key Distribution (QKD) adds an entirely new layer to IT security, designed to protect an organization’s digital infrastructure at the highest level. By utilizing the laws of quantum physics, QKD creates a cryptographic key that remains secure, as any third-party interception attempt is immediately detectable. This level of security ensures that confidential data stays safe, even as technology advances and threats grow.
Shaping the Future towards a Quantum Internet
We are committed to advancing QKD technology to connect quantum processors and enable a full-scale quantum internet, delivering unprecedented levels of security and connectivity. By investing in our QKD solution, organizations prepare for a secure, resilient digital future that can withstand the challenges of tomorrow’s cyber landscape.
Implementing Practical Quantum Security for Critical Applications
Quantum Key Distribution (QKD) is particularly valuable for data transmissions that require the highest levels of security.
Critical Infrastructure: For sectors like transportation systems where data security is critical, QKD enhances the protection of essential infrastructure, prevention of cyber attacks and system reliability. See our deployment at the Port of Rotterdam.
Government and Military Communications: Protecting classified information is crucial. QKD provides a secure channel for communication between government and military entities, ensuring sensitive data remains confidential.
Financial Transactions: In financial sectors, where stock trades, banking transfers, and transactions involve sensitive data and significant funds, QKD delivers secure transactions and protection of financial data.
Healthcare: Safeguarding patient records and medical data is essential. QKD enables secure transmission of confidential healthcare information, supporting both regulatory compliance and patient privacy.
Large Organizations and Telecom: QKD secures internal communications for large organizations, ensuring sensitive information—such as emails and file transfers—remains confidential.
Our Quantum Key Distribution Solution
Our unique Quantum Key Distribution (QKD) technology offers the following benefits that set us apart from existing QKD solutions:
● Unparalleled Scalability: Our QKD architecture allows for true multipoint-to-multipoint QKD. This means that a network can grow to hundreds or even thousands of users without a complete redesign or exponential increase in hardware required by systems using a separate link for each pair of communicating parties.
● Enhanced Security: Our system is immune to all known (and yet-to-be-proposed) detector side-channel attacks, which are identified as the significant vulnerability against all existing QKD implementations, by e.g., ETSI & BSI.
● Enhanced Safeguards: Our Center Hub doesn’t need to be trusted, eliminating the security weakness present in trusted-node QKD networks.
● Cost-Effectiveness: By centralising costly components (e.g., single-photon detectors) in the Center Hub, we significantly reduce the cost per user as the network grows. Eliminating expensive quantum receivers at each End Node makes large-scale deployment economically viable compared to systems where each node requires full QKD capability.
● Future-Proofing: Our technology, based on BSM and patented quantum control systems, aligns with the future of quantum networking applications, providing a clear upgrade path that many current QKD systems lack.
How it Works
Q*Bird is the first to commercially offer equipment to implement a new, secure type of quantum network. Such a network can connect multiple users through a Center Hub in a cost-effective and scalable way, which can provide a secure data connection between many users be protected against eavesdropping.
Eavesdropping on communication systems by malicious parties can lead to significant financial losses, disruption of critical business operations or physical damage. Our quantum communication infrastructure guarantees a connection protected against eavesdropping and will further enhance the logistics chains of the vital infrastructure on the European continent.
Our technology is based on a special implementation of quantum key distribution (QKD). This type of QKD uses a Center Hub to connect users who want to exchange secure communications. A user device will need a connection to just the Center Hub to establish a QKD key with any other End Node in the network. This makes our QKD technology very suitable for scaling up to a many user network. Moreover, the user devices do not contain any quantum measurement devices, making the scalability of our QKD network also cost effective.
