To address really valuable problems, Quantum Computing machines must scale to 100k to millions of physical qubits. Machines of this size cannot be constructed monolithically - the roadmap to utility inevitably mandates a modular and networked architecture of processors that are woven together to form a larger, more powerful machine. This project directly ...

Credible sources estimate the Quantum Computing (QC) market will have a market value of $90-$170B annually in a Fault Tolerant era. It is increasingly accepted that to reach commercial viability, Quantum Networks (QNs), will be needed to scale QC - increasing the number and quality of qubits. The timely development of QNs will thus gate the widespread ado...

Quantum Computing (QC) will offer societal benefits through solving intractable problems across multiple scientific domains. The motivation for this project is to tackle the industry's biggest challenge: scaling. It is increasingly recognised that _useful_ QC can only be delivered by networking together multiple QC nodes into a larger (data-centre-scale),...

Nu Quantum, University of Cambridge, University of Oxford, and Cisco Systems come together to develop and commercialise integrated quantum photonic technology aimed at enabling entanglement-based networking of multi-core quantum computing clusters. Project Medusa employs Integrated Photonic technology to develop a Quantum Networking solution aimed at inte...

Project CALYX : Cold-Atom Light via efficient Cavity Extraction This project addresses a fundamental, rate-limiting, aspect of matter-to-light conversion; proving a principle of cavity-coupling that can unlock greater performance from quantum computing, sensing and networking systems. This project takes Nu Quantum's existing microcavity know-how into Cold...

Quantum computation is heralded as a paradigm shifting technology, to revolutionise drug discovery, chemistry, communications, and even our understanding of the natural world. However, the vast promises of any scientific discovery must be measured against the engineering challenges which hold back its delivery. In this project, partners from industry, aca...

Data is one of the world's most valuable commodities -- affecting every person, every company, every government, everywhere. Most of the world's cybersecurity infrastructure is based on the exchange and use of digital cryptographic keys. Random number generators (RNGs) are essential components of this existing infrastructure, and newer technologies such a...

Major organisations rely on strong encryption, including the process of encryption key agreement. Future quantum computers have the potential to compromise key agreement schemes based on asymmetric encryption and widely deployed Public Key Infrastructure. Over long distances and without quantum repeaters, Business Continuity (BC) can be maintained if comm...

AirQKD establishes a UK ecosystem, from single-photon components to networked quantum systems, to protect short to mid-range communication in free space. In particular we carry out pilot demonstrations of the enabling infrastructure for quantum-secure 5G and autonomous and connected vehicles.

Quantum Key Distribution (QKD) facilitates the secure sharing of encryption keys using quantum technology. These keys can encrypt data for transmission over conventional fibre links across any distance, but QKD itself is limited over fibre to around 150km. Beyond this, 'trusted nodes' are required, but at major risk of creating security vulnerabilities. A...

Nu Quantum partners with the National Physical Laboratory to develop cutting-edge single photon sources and detectors to enable a step-change in performance of free-space quantum key distribution. NPL will use Nu Quantum's arrays of room temperature devices to optimise an automated quantum optical measurement suite: a step towards national standardisation...

"Quantum computers will soon be powerful enough to crack current encryption protocols in seconds - a global threat to all industries, governments and individuals. Quantum cryptography provides a robust solution. Governments are acting now - only within Autumn 2018, over £2 bn public investments in Quantum Technologies have been announced across Europe. On...
