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…
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…
