Abstract

We present the results of the quantum magnetometers dual scheme long-term frequency stability. Such configuration utilizes two magnetic dipole transitions (Zeeman and microwave) and a single optical path in order to reduce magnetic field variations and resonance frequency instability.

The influence of signals correlation on the long-term stability of a tandem of quantum magnetometers with laser pumping

M I Fedorov, Ермак Сергей Викторович, Mikhail V. Petrenko +1 more

The results of studies of the long-term frequency stability as a function of the correlation coefficient for a tandem of two quantum magnetometers with laser pumping of 87 Rb in wall-coated vapour cell are represented. Measurement scheme includes a low-frequency self-generating magnetometer and a quantum microwave discriminator working at magnetic dipole transitions of radio-optical end state resonance. The difference of synchronously detected signals is processed to determine the Allan variance as a function of averaging time and correlation coefficient of signals. These parameters are essentially dependent both on the pumping light intensity and polarization and the intensity of radio fields that are produced in the working cell.

Influence of the dynamic Stark effect on long-term frequency stability of a self-oscillating magnetometer with laser-pumped alkali atoms

A A Baranov, Ермак Сергей Викторович, Nikita K. Kulachenkov +3 more

This paper presents the results of investigation Stark shift effect influence on the long-term stability of a dual scheme of quantum magnetometers. Such scheme allows suppressing Stark shift components when a certain pumping light polarization is applied. As a result, long-term stability of a quantum sensor increases. However, when low-frequency (LF) and microwave fields are attached to a single vapor cell a coherence circulation in hyperfine structure of alkali atoms takes place. Physical origin of this effect is associated with the so called "dressed" atom theory, when atom is "dressed" by LF field. It yields in multiphoton absorption and resonance frequency shift. First estimates for this shift based on density matrix evolution formalism are provided in the paper.

Robust Diamond Quantum Sensing in Double-Quantum 4-Ramsey Interferometry by Dual-Feedback Scheme

Yuta Araki, Takeharu Sekiguchi, Yuji Hatano +11 more

We developed a highly sensitive and long-term stable diamond quantum magnetometer by integrating a dual-feedback system that compensates for common- and differential-mode frequency shifts in double-quantum (DQ) 4-Ramsey interferometry. Detecting extremely weak magnetic-field signals requires extensive signal accumulation to enhance the signal-to-noise ratio. However, deviations from the optimal operating frequencies caused by thermal drift or environmental magnetic noise severely hinder the long-term stability of such a sensing system. To overcome the limitation, we first derived analytical solutions for the signal response to common- and differential-mode detunings based on a detuning-inclusive Hamiltonian to theoretically clarify the robustness limit in DQ 4-Ramsey sensing. Guided by this theoretical model, we introduced synchronized frequency modulation and a dual-feedback scheme to independently track and compensate for these frequency shifts while maintaining an optimal magnetic-field response. The proposed method enabled stable continuous operation against temperature variations of 2.8 K. By maintaining a magnetic field sensitivity of 7.0 pT/Hz^1/2 in the frequency range of 5-100 Hz for a prolonged duration of 4 hours, we achieved an extremely low noise floor of 64 fT/Hz^1/2. During prolonged continuous sensing, the system exhibited the expected 1/T^1/2 scaling with integration time T, and prevented both the underestimation of amplitude and waveform distortion. These results establish a robust approach for long-term DQ 4-Ramsey diamond magnetometry and demonstrate its potential for detecting weak biomagnetic signals.

Signal correlation in the tandem of a spin oscillator and microwave frequency discriminator with laser-pumped alkali atoms

A. A. Baranov, Ермак Сергей Викторович, E. A. Sagitov +2 more

We have studied the influence of low-frequency noise on the stability of resonance frequency of a self-oscillating magnetometer on 87Rb vapor with simultaneous monitoring of the signal of radio-optical resonance on the magnetic-field-dependent microwave transition under laser pumping at the D 2 line of the head doublet. The difference of synchronous records of detected signals reduced to the same scale in magnetic field units was processed to determine the Allan variance as a function of the averaging time. The correlation coefficient characterizing the coupling of detected signals determined by the pumping rate and intensity of radio fields generated in the region of the absorption chamber. The self-oscillating magnetometer can only operate provided that there is laser tuning to the long-wavelength component of the electric-dipole transition.

Single magneto-optical resonance in a modulated RF field

Eugene A. Tsygankov, Sergei A. Zibrov, Alexander S. Zibrov +6 more

A symmetric magneto-optical resonance arising from the single two-quantum RF transition $|{F}_{g}=1,{m}_{{F}_{g}}=\ensuremath{-}1\ensuremath{\rangle}\ensuremath{\leftrightarrows}|{F}_{g}=1,\phantom{\rule{4pt}{0ex}}{m}_{{F}_{g}}=1\ensuremath{\rangle}$ in an optically aligned atomic ensemble is studied in the case when the quadratic Zeeman shift exceeds the width of the resonance. It is shown that the signal-to-noise ratio of the resonance can be significantly increased by applying the phase modulation to the RF field at a frequency close to the value of quadratic Zeeman shift. This theoretical prediction is corroborated by the experimental results with $^{87}\mathrm{Rb}$ atoms. The proposed technique can be used in magnetometers based on atomic alignment or by utilizing multiquantum RF resonances in optically oriented atomic ensembles.

Research on Quantum Frequency Standard Based on NV Center Dual-Frequency Locking and Active Magnetic Field Compensation

Shiyu Guan, xubo liao, Yuxiao Wang +5 more

Abstract To address the interference of environmental magnetic field fluctuations on the diamond Nitrogen-Vacancy (NV) center quantum frequency standard, this paper proposes and implements a composite frequency stabilization scheme based on dual-frequency locking and active magnetic field compensation. Distinct from traditional single-frequency locking schemes, this approach utilizes dual microwave sources to simultaneously lock onto two magnetic resonance transition frequencies of the NV center ground state; one locked peak serves as the frequency standard output, while the other is utilized for magnetic field monitoring. Experimental results demonstrate that this scheme effectively eliminates the influence of ambient stray magnetic fields. At an integration time of 𝜏 = 30 s, the frequency stability at 2.87 GHz reaches 2.53 × 10 −6 , providing a technical reference for the development of robust solid-state quantum frequency standards.
