Researchers at the Fritz Haber Institute have achieved near-complete separation of chiral molecules’ quantum states, challenging previous limitations and opening new research directions in molecular physics.
This breakthrough involves using tailored microwave fields and ultraviolet radiation, allowing for a 96% purity in quantum state control, which has significant implications for understanding biological homochirality and fundamental universe symmetries.
This discovery challenges previous assumptions about the practical limits of quantum state control of chiral molecules and paves the way for new research directions in molecular physics and beyond.
Fundamental Impact on Biological Systems
Chiral molecules, which exist as two non-superimposable mirror image versions called enantiomers, similar to our left and right hands, are fundamental to the fabric of life.
The ability to control these molecules and their quantum states has profound implications, from spatial separation of enantiomers in the gas phase to testing hypotheses about the origins of life’s homochirality – the preference for one mirror image over the other in biological systems.
Achieving Near-Perfect Quantum State Control
Until now, the scientific community believed that perfect control over these molecules’ quantum states was theoretically possible but practically unattainable.
The team at the Fritz Haber Institute, however, has proven otherwise. By creating nearly ideal experimental conditions, they have shown that a 96% purity in the quantum state of one enantiomer (one of the two mirror images) is achievable, with only 4% of the other, moving significantly closer to the goal of 100% selectivity.
Advancements in Experimental Techniques
This breakthrough was made possible through the use of tailored microwave fields combined with ultraviolet radiation, allowing for unprecedented control over the molecules.
In the experiment, a beam of molecules, with their rotational motions mostly suppressed (cooled to a rotational temperature of approximately 1 degree above absolute zero), traverses three interaction regions where it is exposed to resonant UV and microwave radiation.
As a result, marking a significant advancement in molecular beam experiments, chosen rotational quantum states contain almost exclusively the selected enantiomer of a chiral molecule.
New Research Avenues in Molecular Physics
The new experiment opens up new possibilities for studying fundamental physics and chemistry effects involving chiral molecules. The team’s method offers a new avenue for exploring parity violation in chiral molecules – a phenomenon predicted by theory but not yet observed experimentally. This could have profound implications for our understanding of the universe’s fundamental (a)symmetries.
Potential Applications and Future Research
In essence, this study shows that a nearly complete, enantiomer-specific state transfer is achievable and that this method can be applied to the large majority of chiral molecules. It is expected that this discovery will open up important new opportunities in molecular physics, including new research approaches and potential applications.

A new study demonstrates a near-complete control of quantum states in chiral molecules, achieving up to 96% purity. This advancement in molecular physics could profoundly impact our understanding of life’s molecular foundations and the universe’s asymmetries.
Very good! Keep trying!
Researchers should understand that true chirality is mainly manifested between topological vortices and their antivortices, rather than between the high-dimensional spacetime matter formed by their interactions.
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.
The physical phenomena observed in scientific experiments are always just appearances, not the natural essence of things. The natural essence of things needs to be extracted and sublimated based on natural phenomena via mathematical theories. Mathematics is the main environment for modeling problems in other areas. Observations and experiments, theory, and modeling reinforce each other and together lead to our understanding of physical phenomena. After understanding and mastering the natural essence of things, humans can predict more possible natural phenomena, and even manipulate and implement them.

Parity violation is a pseudoscience that misled by surface phenomena of high-dimensional spacetime matter.

The essence of these fallacies is CP violation. Streaker never consider themselves ugly, but rather consider themselves cool.
Low dimensional spacetime matter is the substructure of high-dimensional spacetime matter. Topological vortices and their antivortices have identical spatiotemporal structures. The synchronous effect of countless topological vortex fractal structures makes spatiotemporal motion more complex. Symmetry is mainly manifested between topological vortices and their antivortices, rather than between the high-dimensional spacetime matter formed by their interactions. In theory, it is difficult for two protein molecules, two atoms, or even any observable high-dimensional spacetime objects to be absolutely identical or symmetrical.
