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.
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.
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 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.
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.
In August, Horizon takes a look at the quest to make Europe’s cities environmentally sustainable, while also ensuring a healthy and prosperous population. We speak to geographer Professor Harriet Bulkeley on why cities have such an important role in fighting climate change, what it means for a city to be sustainable and the big challenges that lie ahead. We look at the construction of zero-energy housing, homing in on the case of Nottingham, UK, and find out how scientists are putting nature back into the old Spanish capital of Valladolid. We also talk to the city officials breathing new life into historical buildings in Bologna, Italy, and learn how urban planners and architects are taking emotional feedback into account when designing new public spaces and homes.
How can science help refugees to successfully make a new home in Europe? In July, Horizon examines what we mean when we talk about integration and how research can help refugees build a better future. We speak to Dr Dominik Hangertner at ETH Zurich, Switzerland, about defining integration in order to measure it, the impact of current asylum policies and how big data can help resettlement decisions. We examine how researchers are looking into specific programmes that schools can establish to support adolescent refugees and how media literacy is one such area that can empower young newcomers. We also look at how longer-term mental health needs are being addressed and we speak to researchers and scientists who came to the EU as asylum seekers about the challenges of starting over in a new country.
Rivers in Europe are so congested with concrete obstructions like weirs, bridges and other man-made barriers that they no longer flow freely, which harms the wider environment. Removing these blockages could restore these vital aquatic ecosystems to their former glory.
It is used as a fertiliser to help crops grow, burned as a fuel for heat, and is even used as a building material. But exactly when and how humans began using dung is a mystery that is now starting to be unravelled by researchers.
Free flowing rivers have almost entirely vanished across Europe.
Animal droppings are still used to fertilise crops, as fuel and even for building.
