PhD Studentship in Satellite Quantum Communications

Quantum‑secured networks (QSNs) harness the principles of quantum mechanics to distribute encryption keys using single photons, delivering security that is theoretically unbreakable. While QSNs are already deployed in metropolitan fibre networks, their scalability is constrained by the need for direct optical links between nodes. Satellite‑based quantum key distribution (QKD) offers a transformative solution to extend these networks globally, but achieving this requires compact, robust, and power‑efficient quantum hardware.


Toshiba Europe Ltd has been at the forefront of quantum technology research for over two decades, pioneering breakthroughs in quantum key distribution (QKD), record‑setting communication bit rates, and miniaturisation of quantum systems onto photonic chips. Toshiba QKD systems are now deployed in telecommunication networks worldwide, and the company continues to push the boundaries of quantum‑secured communication.


We are currently inviting applications for a PhD studentship at Toshiba’s Cambridge Research Laboratory in collaboration with Heriot‑Watt University. The project, titled Miniaturised Quantum Systems for Satellite‑Based Secure Networks, will start in October 2026 and focuses on developing next‑generation hardware for satellite quantum networks. This includes miniaturising quantum encoders and decoders for deployment in resource‑constrained environments, enabling global quantum‑secured communication.


You will join a dynamic and supportive team and work on:



  • Design, fabrication, and experimental testing of state‑of‑the‑art satellite QKD systems.
  • Photonic integration of quantum encoders to reduce size and complexity.
  • Development of novel quantum state generation architectures for improved performance and reliability.
  • Exploring architectures that balance performance with size, weight, and power constraints for satellite deployment.

You will work alongside industrial research scientists to leverage ideas across the fields of quantum, optics, electronics and communications to design, conduct and analyse frontier quantum experiments. Research outcomes will be published in leading academic journals and presented at international conferences.


Candidate Profile:

  • A first‑class or upper second‑class degree in a relevant subject i.e. Physics, Electronic Engineering.
  • Strong background in optics and quantum physics.
  • Motivation to join a multidisciplinary team and undertake cutting‑edge experimental research.

What Hiring Managers Look for First in Quantum Computing Job Applications (UK Guide)

Quantum computing is one of the fastest-evolving fields in technology, blending physics, mathematics, computer science and engineering. Roles in this space — from Quantum Algorithm Developer and Quantum Software Engineer to Quantum Research Scientist and Quantum Hardware Specialist — are highly sought after, and hiring managers are exceptionally selective. Because quantum computing is complex and multidisciplinary, recruiters and hiring managers look for clear, concrete evidence of relevant expertise and impact right at the start of your application. They often decide whether to read your CV in detail within the first 10–20 seconds, based on a handful of high-value signals. This guide breaks down exactly what hiring managers look for first in quantum computing applications, how they assess CVs and portfolios, and what you can do to optimise your application to get noticed in the UK quantum job market.

Riverlane Jobs in Quantum Computing: UK Guide for Job Seekers (2026)

If you’re looking for Riverlane jobs in quantum computing, you’re aiming at one of the most important layers in the quantum stack: quantum error correction (QEC). In simple terms, Riverlane focuses on the software, methods & tooling that help quantum computers produce reliable results despite noise. That matters because as quantum hardware scales, the ability to correct errors becomes the difference between “interesting experiments” and “useful quantum computing”. This guide is written for UK job seekers who want to understand: what Riverlane does (in job-seeker language) the roles they hire for the skills that map best to their work how to tailor your CV & LinkedIn how to prepare for interviews how to find & land Riverlane vacancies in the UK You do not need to be a quantum PhD to have a realistic pathway in. But you do need to understand the problem they’re solving & position your experience around it.

The Skills Gap in Quantum Computing Jobs: What Universities Aren’t Teaching

Quantum computing stands at the frontier of technological innovation. Promising breakthroughs in areas as diverse as cryptography, materials discovery, optimisation and machine learning, quantum technologies are shifting from academic research to early commercial deployment. Governments, defence organisations, finance firms and tech innovators around the world — including in the UK — are investing heavily in quantum talent and capability. Yet despite this surge in interest and investment, employers consistently report a troubling trend: Many graduates with quantum computing qualifications are not prepared for real-world quantum computing jobs. This isn’t a reflection on students’ intelligence or effort. Rather, it reveals a persistent skills gap between what universities teach and what organisations actually need. In this article, we’ll explore that gap in depth — what universities do well, where programmes fall short, why the divide persists, what employers actually want, and how jobseekers can bridge that gap to build successful careers in quantum computing.
