Quantum and physics technologies
Quantum and physics technologies hold the potential to enhance communication, measurements, and sensing, helping us to solve complex problems faster.
Quantum mechanics is a branch of physics. It studies the behaviour of particles at the smallest scales such as atoms and subatomic particles.
By using some of the key principles of quantum mechanics - e.g. superposition, tunneling, and entanglement - quantum technologies offer transformative advantages to the space sector:
- enhanced computing power can solve complex problems faster than conventional computing
- quantum communications are highly secure and very fast
- the precision of quantum sensing offers unprecedented accuracy in measurements such as timekeeping or gravitational measurements
Introducing cost efficiencies in secure satellite quantum communications
Quantum key distribution (QKD) networks currently rely on weak laser pulses to produce single photons.
This method is inefficient, especially in satellite communications. Signal loss and short connection times are major challenges.
Deterministic single-photon sources (SPS) offer an innovative solution. By generating single photons on demand with near-perfect efficiency, performance improves.
Unfortunately existing SPS technologies need bulky cryogenic cooling systems. This makes them unsuitable for satellites and some ground stations.
In collaboration with Cambridge University, we are developing room-temperature SPS.
We're using advanced materials such as defect colour centres in hexagonal boron nitride. This enables smaller, lighter, and more cost-effective QKD systems, unlocking the full potential of secure quantum communications for the space industry.
Advancing secure quantum communication technologies
We are developing advanced quantum light sources based on atomically thin materials for secure communication networks, including quantum key distribution.
These lightweight, compact, and resilient materials are well-suited for space applications such as CubeSats.
Our research on electrically triggered single-photon light-emitting diodes offers a promising path towards more energy-efficient solutions, with the potential to simplify system design and reduce operational costs.
We are laying the groundwork for scalable quantum technologies that enable ultra-secure global communication, ensuring reliable data transmission and unbreakable encryption for applications ranging from national security to scientific exploration.
Advancing quantum technologies
Our research contributes to the core scientific principles that underpin quantum technologies, ensuring that technological advances are built on solid theoretical foundations.
By exploring the fundamental nature of quantum mechanics, computing and physics, we can drive innovation in space technologies and satellite communications.
Quantum foundational research not only informs new technologies but also allows us to test hypotheses. This interplay between theory and application is essential for the long-term development of truly new quantum technologies, rather than short-term incremental improvements.
As the global race for quantum advancements accelerates, our work ensures that industry partners benefit from deep scientific understanding, helping them to unlock quantum innovations.
