First Direct Images Reveal Quantum Dance in Complex Molecule

HAMBURG, GERMANY, AUG 11 – Researchers used the European XFEL to capture synchronized atomic vibrations in molecules, confirming zero-point motion predicted by quantum mechanics for the first time.

  • Scientists at Goethe University Frankfurt used the European XFEL in Hamburg, Germany, to capture the hidden, never-ending vibrations of atoms inside molecules, as of August 11, 2025.
  • Classical physics predicts molecules at absolute zero should remain motionless, but the Heisenberg Uncertainty Principle made direct observation of zero-point motion seem impossible.
  • The specialized apparatus recorded each fragment’s position and timing, enabling reconstruction of molecules' original structure using Coulomb Explosion Imaging with ultrashort, high-intensity X-ray pulses.
  • Experiments succeeded in capturing the zero-point motion of atoms, revealing that molecules subtly vibrate at absolute zero and providing new insights into quantum phenomena.
  • Applying this technique to other molecules could open new research avenues and enable time-resolved movies of molecular processes, potentially improving drug design.
