“…By replacing bulky electronics with integrated circuits, portable NV magnetometers usable outside of the laboratory environment may be realized. [37][38][39] On the other hand, the use of scanning stages to resolve single NV centers means additional system complexity and size, even though we made an effort to keep the system compact by utilizing commercially available, off-the-shelf fiber optic components and optical cage system. Still limited to the laboratory use, our system is capable of working with single NV centers, and is fully fledged, in the sense that in principle many of state-of-the-art NMR experiments with single NV centers can be performed.…”

A single nitrogen-vacancy (NV) center in diamond is a prime candidate for a solid-state quantum magnetometer capable of detecting single nuclear spins with prospective application to nuclear magnetic resonance (NMR) at the nanoscale. Nonetheless, an NV magnetometer is still less accessible to many chemists and biologists, as its experimental setup and operational principle are starkly different from those of conventional NMR. Here, we design, construct, and operate a compact tabletop-sized system for quantum sensing with a single NV center, built primarily from commercially available optical components and electronics. We show that our setup can implement state-of-the-art quantum sensing protocols that enable the detection of single 13 C nuclear spins in diamond and the characterization of their interaction parameters, as well as the detection of a small ensemble of proton nuclear spins on the diamond surface. This article providing extensive discussions on the details of the setup and the experimental procedures, our system will be reproducible by those who have not worked on the NV centers previously.

We determine quantum precision limits for estimation of damping constants and temperature of lossy bosonic channels. A direct application would be the use of light for estimation of the absorption and the temperature of a transparent slab. Analytic lower bounds are obtained for the uncertainty in the estimation, through a purification procedure that replaces the master equation description by a unitary evolution involving the system and ad hoc environments. For zero temperature, Fock states are shown to lead to the minimal uncertainty in the estimation of damping, with boson-counting being the best measurement procedure. In both damping and temperature estimates, sequential prethermalization measurements, through a stream of single bosons, may lead to huge gain in precision.

“…Diamond, with its huge potential energy (V 0 ≅ 15.3 eV), makes deep quantum well configurations and, when loaded by suitably-sized cavities, it creates ultra-performing quantum energy selectors. Indeed, diamond with certain nitrogen-based inclusions of significant stability in their electronic level structure has been additionally found to possess remarkable properties for quantum sensing applications 18,20 .…”

“…Diamond-based quantum layouts like nanowires into polycrystalline diamond fabricated via top-down methods allow for large collection efficiency of emitted photons 17 ; moreover, unprecedented coherence of atoms combined with the scalability of a solid-state platform has been achieved by creating suitable defects into diamond 18 . It should be noted that diamond nanophotonic structures are additionally used for efficient light collection in hybrid integration with other material subsystems 19 but, mainly, as solid-state quantum sensors exploiting nitrogen defects 20 .…”

Some of the most influential players from academia and industry have recently expressed concrete interest for quantum engineering applications, especially for new concepts in controlling and processing the quantum signals traveling into condensed matter. An important operation when manipulating particle beams behaving as matter waves concerns filtering with respect to their own energy; such an objective can be well-served by a single planar inclusion of specific size and texture embedded into suitable background. A large number of inclusion/host combinations from realistic materials are tried and the optimally sharp resonance regimes, which correspond to performance limits for such a simplistic structure, are carefully identified. These results may inspire efforts towards the generalization of the adopted approach and the translation of sophisticated inverse design techniques, already successfully implemented for nanophotonic setups, into quantum arena.
