PRESS RELEASE — Greater than 80 years in the past, Erwin Schrödinger, a theoretical physicist steeped within the philosophy of Schopenhauer and the Upanishads, delivered a chain of public lectures at Trinity School, Dublin, which ultimately got here to be printed in 1944 underneath the identify What’s Lifestyles?
Now, within the 2025 Global 12 months of Quantum Science and Generation, Philip Kurian, a theoretical physicist and founding director of the Quantum Biology Laboratory (QBL) at Howard College in Washington, D.C., has used the rules of quantum mechanics, which Schrödinger postulated, and the QBL’s discovery of cytoskeletal filaments displaying quantum optical options, to set a tremendously revised higher sure at the computational capability of carbon-based existence in all the historical past of Earth. Revealed in Science Advances, Kurian’s newest paintings conjectures a dating between this information-processing restrict and that of all topic within the observable universe.
“This paintings connects the dots a few of the nice pillars of 20th century physics—thermodynamics, relativity, and quantum mechanics—for a significant paradigm shift around the organic sciences, investigating the feasibility and implications of quantum news processing in wetware at ambient temperatures,” stated Kurian. “Physicists and cosmologists must strive against with those findings, particularly as they imagine the origins of existence on Earth and in other places within the liveable universe, evolving in live performance with the electromagnetic box.”
Quantum Mechanics And Superradiance
The results of quantum mechanics—the rules of physics that many scientists suppose practice at best small scales—are delicate to disturbances. Because of this quantum computer systems should be held at temperatures less warm than outer house, and best small items, reminiscent of atoms and molecules, generally show quantum homes. Through quantum requirements, organic techniques are rather adverse environments: they’re heat and chaotic, or even their basic parts—reminiscent of cells—are regarded as massive.
However Kurian’s team final 12 months found out a distinctly quantum impact in protein polymers in aqueous resolution, which survives those difficult stipulations on the micron scale, and may additionally provide some way for the mind to give protection to itself from degenerative sicknesses like Alzheimer’s and comparable dementias. Their effects have urged new packages and platforms for quantum computing researchers, they usually constitute a brand new state of mind concerning the dating between existence and quantum mechanics.
In his single-author Science Advances paper, Kurian regarded as an insignificant trifecta of overarching assumptions: same old quantum mechanics, the relativistic pace restrict set by way of mild, and a matter-dominated universe at important mass-energy density. “Mixed with those fairly risk free premises, the exceptional experimental affirmation of single-photon superradiance in a ubiquitous organic structure at thermal equilibrium opens up many new strains of inquiry throughout quantum optics, quantum news concept, condensed topic physics, cosmology, and biophysics,” stated Professor Marco Pettini of Aix-Marseille College and the CNRS Middle for Theoretical Physics (France), who was once no longer related to the paintings.
Quantum Knowledge Processing, Past Biochemical Signaling
The important thing molecule enabling those exceptional homes is tryptophan, an amino acid discovered in lots of proteins that absorbs ultraviolet mild and re-emits it at an extended wavelength. Massive networks of tryptophan shape in microtubules, amyloid fibrils, transmembrane receptors, viral capsids, cilia, centrioles, neurons, and different mobile complexes. The QBL’s affirmation of quantum superradiance in cytoskeletal filaments has the profound end result that each one eukaryotic organisms can use those quantum indicators to procedure news.
To wreck down meals, cells present process cardio respiratory use oxygen and generate loose radicals, which will emit harmful, high-energy UV mild debris. Tryptophan can take in this ultraviolet mild and re-emit it at a decrease calories. And, because the QBL find out about discovered, very massive tryptophan networks can do that much more successfully and robustly as a result of their tough quantum results.
The usual fashion for biochemical signaling comes to ions transferring throughout cells or membranes, producing spikes in an electrochemical procedure that takes a couple of milliseconds for each and every sign. However neuroscience and different organic researchers have best lately turn into conscious that this isn’t the entire tale. Superradiance in those cytoskeletal filaments occurs in a couple of picosecond—a millionth of a microsecond. Their tryptophan networks may well be functioning as quantum fiber optics that let eukaryotic cells to procedure news billions of occasions quicker than chemical processes by myself would permit.
“The results of Kurian’s insights are staggering,” stated Professor Majed Chergui of the École Polytechnique Fédérale de Lausanne (Switzerland) and Elettra-Sincrotrone Trieste (Italy), who supported the 2024 experimental find out about. “Quantum biology—particularly our observations of superradiant signatures from same old protein spectroscopy strategies, guided by way of his concept—has the prospective to open new vistas for figuring out the evolution of dwelling techniques, in mild of photophysics.”
Aneaural Lifestyles And Planetary Computing Capability
Through pondering of organic news processing essentially on the degree of the neuron, many scientists put out of your mind the truth that aneural organisms—together with micro organism, fungi, and vegetation, which shape the majority of Earth’s biomass—carry out refined computations. And as those organisms were on our planet for for much longer than animals, they represent the majority of Earth’s carbon-based computation.
“There are signatures within the interstellar media and on interplanetary asteroids of equivalent quantum emitters, that may be precursors to eukaryotic existence’s computational merit,” stated Dante Lauretta, professor of planetary science and cosmochemistry on the College of Arizona and director of the Arizona Astrobiology Middle, who was once no longer related to the paintings. “Kurian’s predictions supply quantitative bounds, past the colloquial Drake equation, on how superradiant dwelling techniques beef up planetary computing capability. The exceptional homes of this signaling and information-processing modality can be a game-changer within the find out about of liveable exoplanets.”
Efficiency Comparisons With Quantum Computer systems
This newest research has likewise drawn the eye of researchers in quantum computing, for the reason that survival of fragile quantum results in a “noisy” surroundings is of serious hobby to people who wish to make quantum news generation extra resilient. Kurian has had conversations with a number of quantum computing researchers who had been stunned to search out such connections within the organic sciences.
“Those new efficiency comparisons can be of hobby to the massive group of researchers in open quantum techniques and quantum generation,” stated Professor Nicolò Defenu of the Federal Institute of Generation (ETH) Zurich in Switzerland, a quantum researcher who was once no longer related to the paintings. “It’s actually intriguing to look a very important and rising connection between quantum generation and dwelling techniques.”
Within the Science Advances article, Kurian explains and revisits foundational quantum homes and thermodynamic concerns, from an extended line of physicists who made transparent the very important hyperlink between physics and knowledge. Along with his team’s discovery of UV-excited qubits in organic fibers, nearly all existence on Earth has the bodily capability to compute with controllable quantum levels of freedom, permitting garage and manipulation of quantum news with error correction cycles some distance outpacing the newest lattice-based floor codes. “And all this in a heat soup! The quantum computing global must take critical understand,” Kurian stated.
The paintings additionally piqued the eye of quantum physicist Seth Lloyd, a professor of mechanical engineering at MIT and a pioneer within the find out about of quantum computing and the computational capability of the universe. “I applaud Dr. Kurian’s daring and imaginative efforts to use the basic physics of computation to the entire quantity of knowledge processing carried out by way of dwelling techniques over the process existence on Earth. It’s just right to be reminded that the computation carried out by way of dwelling techniques is hugely extra tough than that carried out by way of synthetic ones,” Lloyd stated.
“Within the generation of synthetic intelligences and quantum computer systems, it is very important needless to say bodily rules limit all their behaviors,” Kurian stated. “And but, although those stringent bodily limits additionally practice to existence’s skill to trace, apply, know, and simulate portions of the universe, we will be able to nonetheless discover and make sense of the bright order inside of it, because the cosmic tale unfolds. It’s awe-inspiring that we get to play any such position.”
