Over the years, an enormous effort has been made to establish nitrogen vacancy (N-$V$) centers in diamond as easily accessible and precise magnetic field sensors. However, most of their sensing protocols rely on application bias fields, preventing usage zero- or low-field experiments. We overcome this limitation by exploiting full spin $S=1$ nature N-$V$ center, allowing us detect nuclear signals at zero low with a linearly polarized microwave field. As conventional dynamical decoupling fail...
Quantum sensors based on solid-state defects, such as the nitrogen-vacancy (NV) center in diamond, offer very good room-temperature sensitivity, long-term stability, and potential for calibration-free measurements. However, most quantum still suffer from a bulky size weight, low energy efficiency, high costs, prohibiting their widespread use. Here, we present custom-designed chip-integrated microwave (MW) electronics miniaturized, low-cost, highly scalable magnetometer NV centers diamond....
Solid-state quantum systems that utilize optical and spin degrees of freedom in a spin–photon interface have found widespread application emerging technologies. Recently, molecular qubits gained center stage as precisely tunable entities present compelling alternative to well-established, yet structurally less flexible point defects solid-state systems. In this work, we disclose ground-state triplet (GST) carbenes embedded matrix organic comprising two unpaired electrons close proximity can...

Abstract Diffusion noise is a major source of spectral line broadening in liquid state nano-scale nuclear magnetic resonance with shallow nitrogen-vacancy centres, whose main consequence limited resolution. This limitation arises by virtue the widely accepted assumption that spin signal correlations decay exponentially nano-NMR. However, more accurate analysis diffusion shows survive for longer time due to power-law scaling, yielding possibility improved resolution and altering our...
Solid-state magnetometers based on color centers in diamond are emerging as one of the leading quantum sensors due to their outstanding room-temperature properties, such high sensitivity and calibration-free long-term stability. However, integration into compact systems is still an active area research. To tackle this challenge, paper, we present a magnetometer negatively charged nitrogen-vacancy (NV) using custom-designed, chip-integrated 4-way transmitter. In combination with...

Abstract Nitrogen vacancy (NV) color centers in diamond have shown great potential for various applications quantum technology due to their long coherence times, high sensitivity magnetic fields and atomic scale resolution. However, one major challenge utilizing near surface NV is the decoherence caused by spins charges fluctuating on surface, which affects spin properties of sensors. To reduce induced noise, oxygen treatments such as low power plasma treatment annealing under atmosphere...
