The European Quantum Technologies Roadmap
Antonio Acín, Immanuel Bloch, Harry Buhrman +15
Within the last two decades, Quantum Technologies (QT) have made tremendous progress, moving from Noble Prize award-winning experiments on quantum physics into a cross-disciplinary…
Which role does multiphoton interference play in small phase estimation in quantum Fourier transform interferometers?
Olaf Zimmermann, Vincenzo Tamma
Recently, quantum Fourier transform interferometers have been demonstrated to allow a quantum metrological enhancement in phase sensitivity for a small number n of identical input…
Unambiguous nuclear spin detection using engineered quantum sensing sequence
Zijun Shu, Zhendong Zhang, Qingyun Cao +9
Sensing, localising and identifying individual nuclear spins or frequency components of a signal in the presence of a noisy environments requires the development of robust and sele…
Low field nuclear polarization using Nitrogen Vacancy centers in diamonds
Yonatan Hovav, Boris Naydenov, Fedor Jelezko +1
It was recently demonstrated that bulk nuclear polarization can be obtained using Nitrogen Vacancy (NV) color centers in diamonds, even at ambient conditions. This is based on the…
Quantum simulation of the quantum Rabi model in a trapped ion
Dingshun Lv, Shuoming An, Zhenyu Liu +5
The quantum Rabi model, involving a two-level system and a bosonic field mode, is arguably the simplest and most fundamental model describing quantum light-matter interactions. His…
