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…
Towards a spin-ensemble quantum memory for superconducting qubits
C. Grezes, Y. Kubo, B. Julsgaard +15
This article reviews efforts to build a new type of quantum device, which combines an ensemble of electronic spins with long coherence times, and a small-scale superconducting quan…
Past quantum state analysis of the photon number evolution in a cavity
Théo Rybarczyk, Stefan Gerlich, Bruno Peaudecerf +8
A quantum system can be monitored through repeated interactions with meters, followed by their detection. The state of the system at time t is thus conditioned on the information o…
Quantum computing with an electron spin ensemble
J. H. Wesenberg, A. Ardavan, G. A. D. Briggs +4
We propose to encode a register of quantum bits in different collective electron spin wave excitations in a solid medium. Coupling to spins is enabled by locating them in the vicin…
Scalable designs for quantum computing with rare-earth-ion-doped crystals
Janus H. Wesenberg, Klaus Moelmer, Lars Rippe +1
Due to inhomogeneous broadening, the absorption lines of rare-earth-ion dopands in crystals are many order of magnitudes wider than the homogeneous linewidths. Several ways have be…
Entanglement of large atomic samples: a Gaussian state analysis
Jacob Sherson, Klaus Moelmer
We present a Gaussian state analysis of the entanglement generation between two macroscopic atomic ensembles due the continuous probing of collective spin variables by optical Fara…
