Probing surface charge densities on optical fibers with a trapped ion
Florian R. Ong, Klemens Schüppert, Pierre Jobez +8
We describe a novel method to measure the surface charge densities on optical fibers placed in the vicinity of a trapped ion, where the ion itself acts as the probe. Surface charge…
Ion-based nondestructive sensor for cavity photon numbers
Moonjoo Lee, Konstantin Friebe, Dario A. Fioretto +7
We dispersively couple a single trapped ion to an optical cavity to extract information about the cavity photon-number distribution in a nondestructive way. The photon-number-depen…
Suspended graphene devices with local gate control on an insulating substrate
Florian R. Ong, Zheng Cui, Muhammet A. Yurtalan +6
We present a fabrication process for graphene-based devices where a graphene monolayer is suspended above a local metallic gate placed in a trench. As an example we detail the fabr…
Superconducting qubit as a probe of quantum fluctuations in a nonlinear resonator
Maxime Boissonneault, A. C. Doherty, F. R. Ong +4
In addition to their central role in quantum information processing, qubits have proven to be useful tools in a range of other applications such as enhanced quantum sensing and as…
Ultrasensitive magnetic field detection using a single artificial atom
Mustafa Bal, Chunqing Deng, Jean-Luc Orgiazzi +2
Efficient detection of magnetic fields is central to many areas of research and has important practical applications ranging from materials science to geomagnetism. High sensitivit…
Quantum Heating of a nonlinear resonator probed by a superconducting qubit
F. R. Ong, M. Boissonneault, F. Mallet +5
We measure the quantum fluctuations of a pumped nonlinear resonator, using a superconducting artificial atom as an in-situ probe. The qubit excitation spectrum gives access to the…
