Optimisation of diamond quantum processors
YunHeng Chen, Sophie Stearn, Scott Vella +2
Diamond quantum processors consisting of a nitrogen-vacancy (NV) centre and surrounding nuclear spins have been the key to significant advancements in room-temperature quantum comp…
Microwave device characterisation using a widefield diamond microscope
Andrew Horsley, Patrick Appel, Janik Wolters +4
Devices relying on microwave circuitry form a cornerstone of many classical and emerging quantum technologies. A capability to provide in-situ, noninvasive and direct imaging of th…
Simple atomic quantum memory suitable for semiconductor quantum dot single photons
Janik Wolters, Gianni Buser, Andrew Horsley +5
Quantum memories matched to single photon sources will form an important cornerstone of future quantum network technology. We demonstrate such a memory in warm Rb vapor with on-dem…
Frequency-Tunable Microwave Field Detection in an Atomic Vapor Cell
Andrew Horsley, Philipp Treutlein
We use an atomic vapor cell as a frequency tunable microwave field detector operating at frequencies from GHz to tens of GHz. We detect microwave magnetic fields from 2.3 GHz to 26…
Widefield Microwave Imaging in Alkali Vapor Cells with sub-100 um Resolution
Andrew Horsley, Guan-Xiang Du, Philipp Treutlein
We report on widefield microwave vector field imaging with sub um resolution using a microfabricated alkali vapor cell. The setup can additionally image dc magnetic fields, and can…
Imaging Microwave and DC Magnetic Fields in a Vapor-Cell Rb Atomic Clock
Christoph Affolderbach, Guan-Xiang Du, Thejesh Bandi +3
We report on the experimental measurement of the DC and microwave magnetic field distributions inside a recently-developed compact magnetron-type microwave cavity, mounted inside t…
Imaging of Relaxation Times and Microwave Field Strength in a Microfabricated Vapor Cell
Andrew Horsley, Guan-Xiang Du, Matthieu Pellaton +3
We present a new characterisation technique for atomic vapor cells, combining time-domain measurements with absorption imaging to obtain spatially resolved information on decay tim…
