IBM researchers created the first half-Möbius molecule by twisting a cross-shaped loop and rejoining it.
The team used IBM’s quantum computer to simulate electrons and confirm the half-Möbius shape observed under a microscope.
The half-Möbius molecule twists halfway instead of flipping completely, unlike a full Möbius.
Researchers confirmed the molecule's topology by comparing microscope images with quantum simulations.
The work marks progress in ‘topological’ chemistry and quantum-assisted molecular studies.
The IBM team combined atom manipulation with quantum computing to explore new molecular structures.
scientists quote about the potential impact says such molecules “will have a major impact on the field of molecular science.”
The discovery was published in Science and demonstrates quantum computer value in chemistry research.
The researchers note how quantum computers can scale up calculations by using qubits and superposition.
The IBM team’s work builds on earlier atom-manipulation achievements from 2013.

Researchers created the first molecule with a half-Möbius electronic topology, demonstrated by IBM and collaborators.
The molecule C₁₃Cl₂ was assembled atom by atom on a gold insulating layer at near absolute zero.
Quantum simulations helped decode the topology switching and confirmed a twisted molecular orbital signature.
SqDRIFT, a quantum diagonalization algorithm, ran on up to 100 qubits to study the molecule’s electronic structure.
The work combines atom-scale fabrication and quantum computing to study real quantum matter, not just a toy model.
The topology can be reversibly switched among right-handed, left-handed, and trivial states.
Quantum hardware provided interpretive power for real experimental data rather than just proofs of principle.
The research integrates Feynman’s visions of atom-by-atom engineering and quantum simulations of nature.
The team used scanning tunneling microscopy and atomic force microscopy to map and resolve molecular structure.
The study positions quantum computing as a complementary tool to classical methods in quantum chemistry.
