Researchers have developed a technique to trap light within an organic material, forming a hybrid quantum state that gives rise to novel physical and chemical properties.
An international team of researchers led by the University of Ottawa has gone back to the kitchen cupboard to create a recipe that combines organic material and light to create quantum states.
Professor Jean-Michel Ménard, leader of the Ultrafast Terahertz Spectroscopy group at the Faculty of Science, coordinated with Dr. Claudiu Genes at the Max Planck Institute for the Science of Light (Germany), and with Iridian Spectral Technologies (Ottawa) to design a device which can efficiently modify properties of materials using the quantum superposition with light.
The team designed a two-dimensional planar resonator – known as a metasurface – that captured light. Using a spray coating technique, they then deposited a thin glucose layer on that metasurface to induce a strong interaction between light and glucose molecules in sugar.
Their concept brings researchers closer to being technologically able to harvest some of the unique properties of quantum systems falling in a hybrid state of both light and matter.
Faculty of Science professors Ksenia Dolgaleva and Robert Boyd contributed to the work alongside Professor Menard, the lead author, who discussed the findings published in Nature Communications.
Question: What did you set out to do and what did you find?
Jean-Michel Ménard: “We present an innovative and efficient technique for synthesizing quantum organic materials by combining light and matter. When light in the far-infrared region – at terahertz (THz) frequencies – becomes trapped within an organic material, it can merge with molecules, resulting in a quantum state that exhibits unique properties which are of growing interest because of their potential application in modifying the physical and chemical properties of matter. These intriguing states only arise under specific conditions. Our team identified these critical conditions and created a “photonic trap” or device to effectively confine light within a small volume space during a substantial amount of time. This trap enables a strong coupling regime to be established between light and a molecular ensemble.”
“Unlike previous approaches that relied on optical cavities made of two facing mirrors, we instead designed and tested a two-dimensional planar resonator known as a metasurface. This metasurface effectively allows optical confinement within a planar geometry, opening new practical avenues to explore the quantum regime of strong light-matter interactions.
“Finally, we combined metasurfaces with traditional cavity geometries to form hybrid cavity architectures and observe an enhancement of the coupling strength between light and matter. These results are demonstrated with glucose, an organic compound with properties useful to the fields of biology and medicine.”
Q: Why use THz light and sugar?
JM: “Terahertz light is particularly interesting because it can induce vibrations in many molecules, including glucose molecules in sugar. The energy of vibration of molecules is intricately connected to their properties including their ability to engage in chemical reactions with other molecules. Therefore, by designing platforms enabling a strong coupling between terahertz light and the vibration of molecules, which are fundamental building blocks of organic substances, we have the potential to change their properties to potentially gain control over mechanisms at the foundation of life.”
Q: What did you ultimately find through your research?
JM: “We discovered efficient approaches to couple terahertz light and matter. The most promising concept is based on a structured metallic surface, the metasurface, incorporated into the design of a photonic cavity. As a result, light becomes doubly trapped and remains tightly confined within the device.
“Our robust plug-and-play platform allows potentially many organic materials to be inserted inside this device to create quantum systems with new properties. This is due to the fact that no precise alignment of the device is required to trap the light as this critical condition is mostly fulfilled by the geometry of the metasurface’s metallic pattern. Interestingly, since scalable fabrication techniques exist to fabricate metasurfaces interacting with terahertz light, we believe that these devices could be used relatively soon for real-life applications of quantum-enhanced chemical reactions.”
Q: What kind of impact can this research have?
JM: “These results bring us closer to being technologically able to harvest some of the unique properties of quantum systems consisting of a hybridized state of light and matter. By performing a systematic theoretical and experimental study of different types of photonic resonators, we discovered some novel photonic resonator designs that can create a quantum superposition between a molecular material, glucose, and light in a specific region of the far-infrared spectral window called the terahertz region. Previous work demonstrated that this hybridization process, when it involves terahertz light, modifies the original physical and chemical properties of the material. For example, the presence of a photonic resonator can change the rate of some chemical reactions involving that material.
“In the future, we believe this approach could help regulate some molecular processes, leading to application in medicine for rapid diagnostics and potentially new therapeutic strategies.”

VERY GOOD!
Please ask researchers to think deeply:
1. What is the physical essence of light?
2. What is the physical essence of quantum?
3. Is light and so-called quantum high-dimensional spacetime matter or low dimensional spacetime matter?
and so on.
Scientific research guided by correct theories can help humanity avoid detours, failures, and pomposity. Please witness the exemplary collaboration between theoretical physicists and experimentalists (https://scitechdaily.com/microscope-spacecrafts-most-precise-test-of-key-component-of-the-theory-of-general-relativity/#comment-854286). Some people in contemporary physics has always lived in a self righteous children’s story world. Whose values have been overturned by such a comical and ridiculous reality?
From Physical Review Letters (PRL), to Nature, and Science, even the Proceedings of the National Academy of Sciences (PNAS), the so-called academic journals firmly believe that two high-dimensional spacetime objects (such as two sets of cobalt-60) rotating in opposite directions can be transformed into two objects that mirror each other, and that the asymmetry between the amount of created matter and antimatter led to the matter-dominated Universe as we know it today.
Does the facts tell the so-called academic journals that two sets of cobalt-60 rotating in opposite directions can be transformed into two objects that mirror each other? Does mathematics tell the so-called academic journals that matter and antimatter are asymmetric? When physics no longer believes in facts and mathematics, it is no different from theology.
Naked walkers never consider themselves ugly, but rather consider themselves cool.
Space has physical properties of zero viscosity and absolute incompressibility. Zero viscosity and absolute incompressibility are physical characteristics of ideal fluids. The space with ideal fluid physical characteristics forms vortices via topological phase transitions, which is not difficult to understand mathematically. Once the topological vortex is formed, it occupies space and maintains its presence in time. This is the transition from chaos to order via two bidirectional coupled continuous chaotic systems.
From cosmic accretion disks to particle spins, topological vortex fractal structures are ubiquitous. Symmetry of topological vortex can be used to explore particle behavior under spatial, temporal, and quantum reversals, involving gravitation, discrete and continuous changes. It underpins the consistency of natural laws and experiment reproducibility.
And that state is gonna be called – you guessed it – the Sweet State.
