Investigating the Structure of Vela X Open
Vela X is a prototypical example of a pulsar wind nebula whose morphology and detailed structure have been affected by interaction with the reverse shock of its host supernova remnant. The resulting complex of filamentary structure and mix…
Nanoscale Magnetic Resonance Spectroscopy Using Individual Spin Qubits Open
Nuclear magnetic resonance (NMR) and electron paramagnetic resonance (EPR) are essential tools for both the physical and life sciences, but have been limited to the detection of large ensembles of spins due to their low sensitivity and the…
Magnetic resonance spectroscopy of an atomically thin material using a single-spin qubit Open
Getting a sense of atomically thin materials Two-dimensional materials such as graphene and transition metal dichalcogenides provide a powerful platform for optoelectronic applications. As the materials get thinner, however, characterizing…
Quantum Metrology Enhanced by Repetitive Quantum Error Correction Open
We experimentally demonstrate the protection of a room-temperature hybrid spin register against environmental decoherence by performing repeated quantum error correction whilst maintaining sensitivity to signal fields. We use a long-lived …
Nuclear magnetic resonance detection and spectroscopy of single proteins using quantum logic Open
Sensing single proteins with diamonds Nuclear magnetic resonance is a powerful technique for medical imaging and the structural analysis of materials, but is usually associated with large-volume samples. Lovchinsky et al. exploited the mag…
NMR technique for determining the depth of shallow nitrogen-vacancy centers in diamond Open
We demonstrate a robust experimental method for determining the depth of\nindividual shallow Nitrogen-Vacancy (NV) centers in diamond with $\\sim1$ nm\nuncertainty. We use a confocal microscope to observe single NV centers and\ndetect the …
