Due to a significant technical progress and precise engineering, we are nowadays able to manipulate individual quantum systems, like single atoms, with a precision that has been unthinkable a few decades ago.
Due to a significant technical progress and precise engineering, we are nowadays able to manipulate individual quantum systems, like single atoms, with a precision that has been unthinkable a few decades ago. Quantum technologies open many possibilities for applications, as for instance quantum computers that can solve problems intractable by classical computers, quantum-enhanced sensing and metrology, and quantum simulators that can improve our understanding of complex quantum phenomena. These applications are based on the special properties of quantum mechanics, like the exponential scaling of the Hilbert space, or the collective effects in entangled states.
The EU-funded BRISQ project will combine trapped ion technology and Rydberg interaction to build a highly promising physical platform to host a scalable quantum computer.
Quantum technology carries the promise to revolutionise data processing, communication, and metrology. The current approach towards unlocking this potential builds on scalable and fully coherent devices with high technological complexity.
Quantum information processing is a rapidly developing field of research with a large variety of applications ranging from powerful quantum algorithms to simulations of complex quantum systems.
WACQT is a national research programme, coordinated from Chalmers, that aims to take Swedish research and industry to the forefront of quantum technology.
Researchers from Stockholm University and the Indian Institute of Science Education and Research (IISER) Mohali have reported a practical way to spot one of physics’ strangest predictions: the Unruh effect, which says that an object speeding up (accelerating) would perceive empty space as faintly warm. But, trying to heat something up by accelerating it unimaginably fast is a non-starter in the lab. The team shows how to convert that tiny effect into a clear, timestamped flash of light.
Efficient and reliable detection of motional states is an essential component of many ion-trap experiments. In this recent work a new technique for measuring both Fock and thermal states, based on the Autler-Townes splitting, is demonstrated. The experimental work has been carried out in the group of Markus Hennrich at Fysikum, and was performed in collaboration with the groups of Celso Villas-Boas and Romain Bachelard in São Carlos, Brazil.
An emerging field of physics and engineering is quantum technology, encompassing technologies that rely on the properties of quantum mechanics. Quantum computing being one example of these technologies, representing a paradigm shift for computing technology, since it can outperform much more than existing computers. On February 21 at 13:00, in the: Svedberg salen (FD5), AlbaNova, Professor Akira Furusawa from University of Tokyo, RIKEN Center for Quantum Computing will have a presentation with the title THE FUTURE IS QUANTUM - The development of Quantum Computing.
