Magnetic resonance with squeezed microwaves
A. Bienfait, P. Campagne-Ibarcq, A. Holm-Kiilerich +9
Vacuum fluctuations of the electromagnetic field set a fundamental limit to the sensitivity of a variety of measurements, including magnetic resonance spectroscopy. We report the u…
Strong Coupling Between Whispering Gallery Photons and Spin States of Iron Group Impurity Ions
Maxim Goryachev, Warrick G. Farr, Natalia C. Carvalho +5
Interaction of Whispering Gallery Modes (WGM) with dilute spin ensembles in solids is an interesting paradigm of Hybrid Quantum Systems potentially beneficial for Quantum Signal Pr…
Multi-photon dressing of an anharmonic superconducting many-level quantum circuit
Jochen Braumüller, Joel Cramer, Steffen Schlör +10
We report on the investigation of a superconducting anharmonic multi-level circuit that is coupled to a harmonic readout resonator. We observe multi-photon transitions via virtual…
Hybrid quantum circuit with implanted erbium ions
S. Probst, N. Kukharchyk, H. Rotzinger +6
We report on hybrid circuit QED experiments with focused ion beam implanted Er ions in YSiO coupled to an array of superconducting lumped element microwave resonator…
3D Cavity quantum electrodynamics with a rare-earth spin ensemble
S. Probst, A. Tkalcec, H. Rotzinger +6
We present cavity QED experiments with an Er:YSO crystal magnetically coupled to a 3D cylindrical sapphire loaded copper resonator. Such waveguide cavities are promising for the re…
Strong coupling of an Er3+ doped YAlO3 crystal to a superconducting resonator
A. Tkalcec, S. Probst, D. Rieger +7
Quantum memories are integral parts of both quantum computers and quantum communication networks. Naturally, such a memory is embedded into a hybrid quantum architecture, which has…
