The so-called second quantum revolution is in full swing, with scientists not only able to understand what happens at a sub-atomic level but also control this quantum behaviour enough to develop new technologies. Six months after the launch of the EU’s €1 billion quantum flagship initiative to kickstart a European quantum technologies industry, we take a look at the potential of quantum to revolutionise our future. We speak to one researcher who is helping to build a quantum computer about the global race to do this and how Europe is faring. We take a look at the threat and promise of quantum technologies in the field of cryptography and find out how quantum simulators can be used to solve non-quantum problems. And finally, we speak to the scientists who are using quantum mechanics to improve the performance of brain scanners and better diagnose medical conditions.

Quantum technology could revolutionise the detection and treatment of diseases

When you hear the word ‘quantum’, you may imagine physicists working on a new ground breaking theory. Or perhaps you’ve read about quantum computers and how they might change the world. But one lesser-known field is also starting to reap the benefits of the quantum realm – medicine.

Quantum simulation could help flights run on time

A powerful new form of computing could help scientists design new types of materials for nanoelectronics, allow airlines to solve complex logistical problems to ensure flights run on time, and tackle traffic jams to keep cars flowing more freely on busy roads.

Quantum – a double-edged sword for cryptography

Quantum computers pose a big threat to the security of modern communications, deciphering cryptographic codes that would take regular computers forever to crack. But drawing on the properties of quantum behaviour could also provide a route to truly secure cryptography.

‘Quantum computers will soon outperform classical machines’

European scientists have spent 100 years developing the field of quantum mechanics – a branch of physics dealing with the atomic and subatomic scale – and we need to reap the profits now that quantum computers and other technologies are becoming a reality, according to Dr Thomas Monz from the University of Innsbruck, Austria.

Taking stock: Where next for research?

The world looks very different from this time last year. The coronavirus pandemic has highlighted the centrality of science, research and innovation, accelerated some changes already in the works, but also exposed our weaknesses. In September, Horizon looks at how the pandemic is reshaping Europe in areas including health research, work, tech, transport and food – and how research can contribute to Europe’s recovery over the coming years. We will also be covering the European Research & Innovation Days at the end of the month, which will bring together scientists, policymakers, entrepreneurs and citizens to debate how research and innovation can ensure that the transition to a post-coronavirus society is sustainable, inclusive and resilient.

Our shifting surface

In August, Horizon looks at one of the features that makes Earth unique and habitable: plate tectonics. We explore what we know – and still don’t know – about how the shifting plates beneath our feet shape our planet. We speak to researcher Dr Kate Rychert, who wants to understand what makes a plate plate-like, and delve into one of the outstanding mysteries in the subject – how and why plate tectonics began. We find out about the link between mountain formation, erosion and climate change, and we look at what moonquakes and marsquakes can reveal about tectonic activity elsewhere.

Secret of how fish repair their hearts could help cardiac patients

The ability of certain fish to heal damage to their hearts could lead to new treatments for patients who have suffered heart attacks and may also help to unravel how the lifestyle of our parents and grandparents can affect our own heart health.

How waste CO2 is helping to turn renewable energy into liquid fuel

Storing power generated by strong winds or bright sunshine by turning it into liquid fuel such as methanol can help to ensure green energy does not go to waste, without having to rely on batteries.
