Researchers demonstrated electromagnetically induced quantum coherence in a quantum well. A strong coupling field created a narrow transparency feature, showing phase-locked quantum coherence between electron subband levels.

Area of Science:

  • Quantum physics
  • Solid-state physics
  • Optics

Background:

  • Quantum wells confine electrons to specific energy levels.
  • Electromagnetically induced transparency (EIT) is a quantum interference effect.
  • Controlling quantum coherence is crucial for quantum technologies.

Purpose of the Study:

  • To demonstrate electromagnetically induced quantum coherence between three electron subband levels in a quantum well.
  • To investigate the effect of a strong coupling field on intersubband absorption.
  • To understand the underlying mechanism of phase-locked quantum coherence.

Main Methods:

  • Experimental demonstration of quantum coherence.
  • Application of a strong coupling field, two-photon resonant with the 1-3 intersubband transition.

  • Theoretical analysis using a density matrix method and adapted linear response theory.

    • Main Results:

    • Observation of a pronounced narrow transparency feature in the 1-2 absorption line.
    • Demonstration of quantum coherence between three nearly equally spaced energy levels.
    • Confirmation of simultaneous "phase-locked" quantum coherence driven by a single coupling field.

    Conclusions:

    • Electromagnetically induced quantum coherence is achievable between three subband levels in a quantum well.
    • A single coupling field can drive multiple quantum states into phase-locked coherence.
    • The findings provide insights into controlling quantum interference for potential applications.
