Solid-state spin systems including nitrogen-vacancy (NV) centers in diamond constitute an
increasingly favored quantum sensing platform. However, present NV ensemble devices …

“Quantum sensing” describes the use of a quantum system, quantum properties, or quantum
phenomena to perform a measurement of a physical quantity. Historical examples of …

Crystal defects in diamond have emerged as unique objects for a variety of applications,
both because they are very stable and because they have interesting optical properties …

Quantum sensing takes advantage of well-controlled quantum systems for performing
measurements with high sensitivity and precision. We have implemented a concept for …

Quantum technologies represent a rapidly evolving field in which the specific properties of
quantum mechanical systems are exploited to enhance the performance of various …

Quantum sensors such as spin defects in diamond have achieved excellent performance by
combining high sensitivity with spatial resolution. Unfortunately, these sensors can only …

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 …

We report the detection and polarization of nuclear spins in diamond at room temperature by
using a single nitrogen-vacancy (NV) center. We use Hartmann-Hahn double resonance to …

Quantum adiabatic passages can be greatly accelerated by a suitable control field, called a
counter-diabatic field, which varies during the scan through resonance. Here, we implement …

We present measurements of spin relaxation times (T 1, T 1 ρ, T 2) on very shallow (≲ 5 nm)
nitrogen-vacancy centers in high-purity diamond single crystals. We find a reduction of spin …
