High-frequency phonons are promising for quantum information but spectral diffusion limits coherence. This study shows adjacent phonon modes are not time-correlated, advancing understanding of dephasing mechanisms in quantum memories.

Area of Science:

  • Quantum physics
  • Optomechanics
  • Solid-state physics

Background:

  • High-frequency phonons are explored as quantum information carriers and memories due to their coherent interactions and slow group velocity.
  • Strongly confined phonons in waveguide geometries offer long lifetimes but suffer from spectral diffusion, limiting coherence times.
  • Coupling to two-level systems is a suspected cause of spectral diffusion, but the exact mechanisms remain unclear.

Purpose of the Study:

  • To investigate the origin and mechanisms of spectral diffusion limiting phonon coherence times.
  • To analyze the temporal correlation between adjacent mechanical modes in a system.
  • To contribute to a comprehensive understanding of dephasing in mechanical quantum buses and memories.

  • Performed a time-domain study on two adjacent mechanical modes with a frequency difference of approximately 5 MHz.
  • Developed a theoretical model to explain the observed phenomena.
  • Conducted Monte Carlo simulations to validate the theoretical model and experimental findings.

    • Main Results:

    • Demonstrated that the frequency positions of the two adjacent mechanical modes are not correlated in time.
    • The experimental results align with the developed theoretical model and Monte Carlo simulations.
    • This finding provides crucial insights into the dynamics of spectral diffusion.

    Conclusions:

    • The lack of temporal correlation between adjacent phonon modes offers a new perspective on spectral diffusion.
    • This research is a significant step towards understanding and mitigating dephasing in phononic quantum systems.
    • The findings pave the way for improved design and application of mechanical quantum buses and memories.
