Spin-to-Charge conversion with electrode confinement in diamond
Liam Hanlon, Lachlan Oberg, Yun Heng Chen +1
The nitrogen-vacancy (NV) center in diamond has a wide range of potential applications in quantum metrology, communications and computation. The key to its use lies in how large th…
Nanoscale vector electric field imaging using a single electron spin
M. S. J Barson, L. M. Oberg, L. P. McGuinness +4
The ability to perform nanoscale electric field imaging of elementary charges at ambient temperatures will have diverse interdisciplinary applications. While the nitrogen-vacancy (…
Nitrogen overgrowth as a catalytic mechanism during diamond chemical vapour deposition
Lachlan M. Oberg, Marietta Batzer, Alastair Stacey +1
Nitrogen is frequently included in chemical vapour deposition feed gases to accelerate diamond growth. While there is no consensus for an atomistic mechanism of this effect, existi…
A solution to electric-field screening in diamond quantum electrometers
Lachlan M. Oberg, Mitchell O. de Vries, Liam Hanlon +4
There are diverse interdisciplinary applications for nanoscale resolution electrometry of elementary charges under ambient conditions. These include characterization of 2D electron…
Optimised fast gates for quantum computing with trapped ions
Evan P. G. Gale, Zain Mehdi, Lachlan M. Oberg +3
We present an efficient approach to optimising pulse sequences for implementing fast entangling two-qubit gates on trapped ion quantum information processors. We employ a two-phase…
Spin coherent quantum transport of electrons between defects in diamond
Lachlan M Oberg, Eric Huang, Prithvi M Reddy +6
The nitrogen-vacancy color center in diamond has rapidly emerged as an important solid-state system for quantum information processing. While individual spin registers have been us…
