Investigating the Structure of Vela X
P. Slane, I. Lovchinsky, C. Kolb +9
Vela X is the prototypical example of a pulsar wind nebula whose morphology and detailed structure have been affected by the interaction with the reverse shock of its host supernov…
Quantum metrology enhanced by repetitive quantum error correction
Thomas Unden, Priya Balasubramanian, Daniel Louzon +11
The accumulation of quantum phase in response to a signal is the central mechanism of quantum sensing, as such, loss of phase information presents a fundamental limitation. For thi…
NMR Technique for Determining the Depth of Shallow Nitrogen-Vacancy Centers in Diamond
Linh M. Pham, Stephen J. DeVience, Francesco Casola +10
We demonstrate a robust experimental method for determining the depth of individual shallow Nitrogen-Vacancy (NV) centers in diamond with nm uncertainty. We use a confocal…
Magnetic resonance detection of individual proton spins using a quantum reporter network
Alexander O. Sushkov, Igor Lovchinsky, Nicholas Chisholm +3
We demonstrate a method of magnetic resonance imaging with single nuclear-spin sensitivity under ambient conditions. It employs a network of isolated electronic-spin quantum bits (…
Nanoscale NMR Spectroscopy and Imaging of Multiple Nuclear Species
Stephen J. DeVience, Linh M. Pham, Igor Lovchinsky +10
Nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI) are well-established techniques that provide valuable information in a diverse set of disciplines but are curr…
All-optical sensing of a single-molecule electron spin
A. O. Sushkov, N. Chisholm, I. Lovchinsky +8
We demonstrate an all-optical method for magnetic sensing of individual molecules in ambient conditions at room temperature. Our approach is based on shallow nitrogen-vacancy (NV)…
Quantum Error Correction for Metrology
Eric M. Kessler, Igor Lovchinsky, Alexander O. Sushkov +1
We propose and analyze a new approach based on quantum error correction (QEC) to improve quantum metrology in the presence of noise. We identify the conditions under which QEC allo…
