Abstract said:Within the last two decades, quantum technologies (QT) have made tremendous progress, moving from Nobel Prize award-winning experiments on quantum physics (1997: Chu, Cohen-Tanoudji, Phillips; 2001: Cornell, Ketterle, Wieman; 2005: Hall, Hänsch-, Glauber; 2012: Haroche, Wineland) into a cross-disciplinary field of applied research. Technologies are being developed now that explicitly address individual quantum states and make use of the 'strange' quantum properties, such as superposition and entanglement. The field comprises four domains: quantum communication, where individual or entangled photons are used to transmit data in a provably secure way; quantum simulation, where well-controlled quantum systems are used to reproduce the behaviour of other, less accessible quantum systems; quantum computation, which employs quantum effects to dramatically speed up certain calculations, such as number factoring; and quantum sensing and metrology, where the high sensitivity of coherent quantum systems to external perturbations is exploited to enhance the performance of measurements of physical quantities. In Europe, the QT community has profited from several EC funded coordination projects, which, among other things, have coordinated the creation of a 150-page QT Roadmap (http://qurope.eu/h2020/qtflagship/roadmap2016). This article presents an updated summary of this roadmap.

Quantum information research is a field of study that combines principles from quantum mechanics and information theory to understand and manipulate information at the quantum level. It involves the use of quantum systems, such as atoms and photons, to store and process information in ways that are not possible with classical systems.
Quantum information research has the potential to revolutionize fields such as cryptography, communication, and computing. It could lead to the development of unbreakable encryption methods, ultra-fast communication networks, and powerful quantum computers that can solve complex problems that are currently intractable for classical computers.
One of the main challenges in quantum information research is the delicate nature of quantum systems. These systems are easily affected by external disturbances, making it difficult to maintain their quantum properties. Another challenge is the development of reliable and scalable quantum hardware, which is necessary for practical applications of quantum information.
There are several different approaches to quantum information research, including quantum computing, quantum communication, and quantum sensing. Each of these approaches focuses on different aspects of quantum information, such as manipulating quantum states, transmitting quantum information, and measuring quantum systems.
The future of quantum information research is exciting and full of possibilities. Some potential future developments include the development of fault-tolerant quantum computers, the creation of quantum internet networks, and the exploration of quantum artificial intelligence. There is also ongoing research into the fundamental principles of quantum mechanics, which could lead to new breakthroughs in quantum information.
