Ilan Gur is not your classic civil servant.The cheerful Californian, wearing a T-shirt, black trainers and blue-framed glasses, looks more tech bro than government mandarin. His benefits package is also more Silicon Valley than Whitehall: £455,000 including salary, bonus and pension contributions.
But Gur, 45, does not have a classic civil service job. He is chief executive of Aria,the Advanced Research and Invention Agency,known as Britain’s “moonshot factory”.
The organisation, the brainchild of Dominic Cummings when he was in No 10, was set up in 2022 with a “high-risk, high-reward” ethos to make discoveries so monumental they would change the world.
While Cummings was a controversial figure in government, his vision has received cross-party support. The Conservatives granted Aria an initial £800 million budget to last until this year, and last week Labor announced another £1.2 billion to cover the next four years. By 2030 Aria will receive £400 million a year.
“For us,success means not just a world-changing technology,but drastically transforming the future of the UK,” says gur.

I meet Gur as he prepares to step down after three years at the helm of Aria. He is upbeat about his time in the UK, and – perhaps surprisingly given recent headlines about pharmaceutical companies leaving our shores – excited about the state of British science.
The typical undergraduate at a top British university,he says,”knows their field deeper than any students at MIT”. In the past, this academic strength was hampered by bureaucracy and arcane institutions, but the UK is growing in the drive and energy that it lacked in the past, Gur says.
Rather than focusing on purely intellectual goals as they were in the past, British scientists today have an entrepreneurial spirit that was previously lacking, he says.”You have a critical mass of people who do want to be operating differently, who want to be more translational, more applied, more entrepreneurial in their work. It is still a subculture,but there’s a critical mass now of people who have this spirit and this ambition.”
A single breakthrough is all it would take for Aria – and the UK – to make history, Gur says. “We are asking ourselves all the time, what will be our ChatGPT moment, what will be our Ozempic moment?”

Quantum Computing: A Beginner’s Guide
Quantum computing is a revolutionary field poised to reshape industries from medicine and materials science to finance and artificial intelligence. Unlike classical computers that store facts as bits representing 0 or 1,quantum computers leverage the principles of quantum mechanics to store information as qubits. This allows them to tackle complex problems currently intractable for even the most powerful supercomputers. This guide provides a foundational understanding of quantum computing, its core concepts, potential applications, and current challenges.
What is Quantum Computing?
At its core,quantum computing exploits the strange and counterintuitive laws of quantum mechanics. Two key principles underpin this technology:
- Superposition: A qubit can exist in a combination of states – 0, 1, or both together. Imagine a coin spinning in the air; it’s neither heads nor tails until it lands. This allows quantum computers to explore many possibilities concurrently.
- Entanglement: two or more qubits can become linked together in such a way that they share the same fate,no matter how far apart they are. Measuring the state of one entangled qubit instantly reveals the state of the other. IBM Quantum provides a detailed explanation of this phenomenon.
These principles enable quantum computers to perform certain calculations exponentially faster than classical computers. However, it’s important to note that quantum computers aren’t meant to replace classical computers entirely. They excel at specific types of problems, while classical computers remain more efficient for everyday tasks.
Qubits vs. Bits
The fundamental difference between classical and quantum computing lies in the unit of information.classical computers use bits,which represent either a 0 or a 1. Quantum computers use qubits. A qubit, thanks to superposition, can represent 0, 1, or a probability of both. This dramatically increases the computational possibilities. Mathematically, a qubit’s state is described by a vector in a two-dimensional complex space, allowing for a richer portrayal of information.
Applications of Quantum Computing
The potential applications of quantum computing are vast and transformative:
- Drug Discovery and Materials Science: Simulating molecular interactions to design new drugs and materials with specific properties. NIST highlights the role of quantum computing in materials discovery.
- Financial Modeling: Optimizing investment portfolios,detecting fraud,and assessing risk with greater accuracy.
- Cryptography: Breaking existing encryption algorithms and developing new, quantum-resistant cryptography. Stack exchange offers a good overview of post-quantum cryptography.
- Artificial Intelligence: accelerating machine learning algorithms and enabling the development of more powerful AI models.
- Optimization Problems: Solving complex optimization problems in logistics, supply chain management, and scheduling.
Current Challenges and Future Outlook
Despite its immense potential, quantum computing faces notable challenges:
- Decoherence: Qubits are extremely sensitive to their habitat, and maintaining their quantum state (superposition and entanglement) is challenging. Decoherence leads to errors in calculations.
- Scalability: Building and maintaining large-scale, stable quantum computers with a sufficient number of qubits is a major engineering hurdle.
- Error Correction: developing effective error correction techniques to mitigate the effects of decoherence and other errors is crucial.
- Software Development: Creating quantum algorithms and software tools requires a new way of thinking about computation.
several companies and research institutions are actively working to overcome these challenges. google Quantum AI, IBM Quantum, and Rigetti Computing are leading the way in developing quantum hardware and software. The field is rapidly evolving, and significant breakthroughs are expected in the coming years.
