A team of researchers from the University of East Anglia has unveiled an innovative approach that utilizes quantum light to identify quantum sound. This research enhances comprehension of the complex quantum interrelations between molecular oscillations and light particles, also known as photons. The implications of this work are anticipated to deepen our understanding of molecular-scale interactions between light and matter, and could potentially open new pathways in both quantum technology and biological sciences. The team’s work may also catalyze the development of novel methods for the direct detection of individual quanta of sound, or phonons.
Scholars from the University of East Anglia have suggested an alternative method that employs quantum light to discern quantum sound.
A study recently disclosed in the journal Physical Review Letters explores the quantum-mechanical relationships between molecular vibrations and photons. This breakthrough is expected to contribute to a more refined understanding of how light and matter interact at molecular levels.
Moreover, this research offers the potential to address key questions concerning the relevance of quantum effects in various applications, including emergent quantum technologies and biological systems.

The Debate in Chemical Physics
Dr. Magnus Borgh, from the School of Physics at the University of East Anglia, articulated, “In the domain of chemical physics, there exists an enduring debate concerning the nature of mechanisms by which light energy is transferred within molecular structures.
“Is the fundamental nature of these processes quantum-mechanical or classical? Molecules are inherently complicated, exhibiting continuous vibrations. What impact do these vibrations have on any quantum-mechanical events occurring within the molecule?
“Conventional investigations into these processes often employ polarization-based techniques, a property of light that sunglasses exploit to diminish glare. However, this is inherently a classical phenomenon.
“Insights from quantum optics, a subfield of physics focusing on the quantum attributes of light and its interactions with atomic matter, may offer avenues to directly explore authentic quantum effects within molecular systems.”
Importance of Photon-Phonon Correlations in Quantum Behavior
The study of emitted light correlations from a molecule situated within a laser field can disclose quantum behaviors. Such correlations provide insights into the probability of two closely emitted photons and can be evaluated using established methodologies.
Ben Humphries, a Ph.D. candidate in theoretical chemistry at the University of East Anglia, remarked, “Our investigation indicates that the exchange of phonons—quantum-mechanical particles of sound—between a molecule and its surrounding environment manifests as a discernible pattern in photon correlations.”
Contrary to photons, which are regularly generated and measured in laboratories globally, individual phonons generally cannot be measured in a similar fashion.
Potential Implementations and Forthcoming Directions
These groundbreaking discoveries furnish a set of tools for probing the realm of quantum sound within molecular structures.
The principal investigator, Dr. Garth Jones from the University of East Anglia’s School of Chemistry, stated, “Our team has also calculated correlations between photons and phonons.”
“It would indeed be groundbreaking if our publication could stimulate the invention of fresh experimental methodologies for the direct detection of individual phonons,” he concluded.
