We study the resonant optical transitions of a single nitrogen-vacancy (NV) center that is coherently dressed by strong mechanical drive. Using gigahertz-frequency diamond resonator strain-coupled to an NV center's orbital states, we demonstrate coherent Raman sidebands out ninth order and orbital-phonon interactions mix two excited-state branches. These are spectroscopically revealed through multi-phonon Rabi splitting branches which scales as function driving amplitude, successfully...

Diamond-based microelectromechanical systems (MEMS) enable direct coupling between the quantum states of nitrogen-vacancy (NV) centers and phonon modes a mechanical resonator. One example, diamond high-overtone bulk acoustic resonators (HBARs), feature an integrated piezoelectric transducer support high-quality factor resonance into GHz frequency range. The allow manipulation deeply embedded NV with long spin orbital coherence times. Unfortunately, spin-phonon rate is limited by large...

We use a bulk acoustic wave resonator to demonstrate coherent control of the excited orbital states in diamond nitrogen-vacancy (NV) center at cryogenic temperature. Coherent quantum is an essential tool for understanding and mitigating decoherence. Moreover, characterizing controlling central challenge networking, where optical coherence tied coherence. study resonant multi-phonon Rabi oscillations both frequency time domain, extracting strength orbital-phonon interactions acoustically...

The methods for controlling spin states of negatively charged nitrogen-vacancy (NV) centers using microwave (MW) or radio frequency (rf) excitation fields electron and nuclear transitions are effective in strong magnetic where a level anticrossing (LAC) occurs. A LAC can also occur at zero field the presence transverse strain electric diamond crystal, leading to mixing states. In this Rapid Communication, we investigate zero-field NV dual-frequency spectroscopy. Under rf modulation states,...

The spectrally narrow, spin-dependent optical transitions of nitrogen-vacancy (N-$V$) center defects in diamond can be harnessed for quantum networking applications. Key to such schemes is the generation indistinguishable photons. Two challenges limit scalability systems: defect-to-defect variations transition frequencies caused by local strain variation, and spectral diffusion on repeated measurement photoexcitation nearby charge traps. In this experimental study we undertake a...

Using a high quality factor 3 GHz bulk acoustic wave resonator device, we demonstrate the acoustically driven single quantum spin transition ($|{m}_{s}=0⟩\ensuremath{\leftrightarrow}|\ifmmode\pm\else\textpm\fi{}1⟩$) for diamond nitrogen-vacancy (N-$V$) centers and characterize corresponding stress susceptibility. A key challenge is to disentangle unintentional magnetic driving field generated by device current from intentional within device. We quantify these fields independently using Rabi...

We demonstrate the application of principal-component analysis (PCA) to particle motion data in form a time series images. PCA has ability resolve and isolate spatiotemporal patterns data. Using simulated data, we show that this translates into separate individual frequency components motion. also can be used extract fluid viscosity from images particles undergoing Brownian thus provides an efficient alternative more traditional particle-tracking methods for microrheological

Starting from a first-order approximate field description function for laser pulses, the method currently used to chirped pulse (CLP) substitutes frequency and wave vector related variables with spatiotemporally varying functions. We investigated error involved by calculating relative deviation Maxwell equations. Errors electric magnetic fields are analyzed separately, behaviors parameter changes (that is, in width, duration chirp parameter) were studied. Results show that aberration...

Diffusion models have emerged as a powerful framework for generative modeling, achieving state-of-the-art performance across various tasks. However, they face several inherent limitations, including training-sampling gap, information leakage in the progressive noising process, and inability to incorporate advanced loss functions like perceptual adversarial losses during training. To address these challenges, we propose an innovative end-to-end training that aligns sampling processes by...
