Amplification of weak microwave signals with minimal added noise is importance to science and technology. Artificial quantum systems, based on superconducting circuits, can now amplify detect even single photons. However, this requires operating at millikelvin temperatures. Natural systems also be used for low-noise amplification using stimulated emission effects; however, they generate a higher noise, especially when above ~1 K. Here, we demonstrate the use electron spins in diamond as...
Diamonds have been shown to be an excellent platform for quantum computing and sensing applications. These applications are enabled by the presence of defects in lattice, which also known as color centers. The most common nitrogen-based defect synthetic diamonds is paramagnetic nitrogen substitution (P1) center. While majority rely on nitrogen-vacancy (NV) centers, properties latter heavily influenced spatial distribution P1 Hence, understanding mutual interactions centers crucial successful...
The most common lattice defect in high-pressure high-temperature (HPHT) diamonds is the nitrogen substitution center. This a paramagnetic with single unpaired electron spin coupled to ¹⁴𝑁 nuclear forming an 𝑆 = ½, 𝐼 1 system. While P1 centers have been studied by EPR spectroscopy for decades, only recently did their behavior at ultra-high (> 12 T) magnetic fields become of interest. because were found be very efficient polarizing agents Dynamic Nuclear Polarization (DNP) experiments,...
State mixing at a high magnetic field in the well-studied nitrogen substitutions diamonds leads to unique electron spin spectral properties.
