Atom-chip-based generation of entanglement for quantum metrology
The experimental generation of multi-particle entanglement on an atom chip is reported by controlling elastic collisional interactions with a state-dependent potential to generate spin-squeezed states of a two-component Bose–Einstein condensate; such states are a useful resource for quantum metrology.
Coherent manipulation of Bose–Einstein condensates with state-dependent microwave potentials on an atom chip
Entanglement-based technologies, such as quantum information processing, quantum simulations and quantum-enhanced metrology, have the potential to revolutionize our way of computing and measuring,
Quantum metrology with a scanning probe atom interferometer.
This work uses a small Bose-Einstein condensate on an atom chip as an interferometric scanning probe to map out a microwave field near the chip surface with a few micrometers resolution and overcomes the standard quantum limit of interferometry.
The quantum technologies roadmap: a European community view
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:
The European Quantum Technologies Roadmap
An updated summary of the QT Roadmap is presented, including sections on Quantum Theory and Software, and on Quantum Control, as both are important areas of research that cut across all four domains.
Imaging of microwave fields using ultracold atoms
We report a technique that uses clouds of ultracold atoms as sensitive, tunable, and noninvasive probes for microwave field imaging with micrometer spatial resolution. The microwave magnetic field
Europe’s Quantum Flagship initiative
As the first applications leap out of research laboratories toward commercialization, the global race for dominance in the maturing field of quantum technologies is becoming ever fiercer. To retain
The European quantum technologies flagship programme
The history leading to the quantum technologies flagship programme is summarized and an overview of the strategic research agenda for quantum communication is given, which the flagship will pursue during its 10-year runtime.
Elastic Slowing of Supersonic Beams
allowed me great freedom in my work and put a lot of trust in me. Nevertheless, you were always there with good advice and great ideas when I needed you. I am very proud that I was given the
Towards magnetic slowing of atoms and molecules
We outline a method to slow paramagnetic atoms or molecules using pulsed magnetic fields. We also discuss the possibility of adiabatically slow trapped particles by decelerating a moving magnetic
