First ‘half Möbius’ carbon chain wows chemists
Researchers synthesized a carbon molecule with a novel half-Möbius topology confirmed via IBM quantum computing and advanced microscopy, enabling tunable quantum molecular states.
- On March 5, IBM Research and University of Manchester chemists synthesized a carbon-based molecule with an unprecedented half-Möbius topology, confirmed using IBM's quantum computers.
- Classical‑computing limits forced the team to run models on IBM quantum computer because classical computers struggle to simulate interacting electrons with exponential scaling.
- With AFM and STM, researchers assembled the molecule on a thin gold surface using 13 carbon atoms and two chlorine atoms, creating a half‑Möbius twist with a 90° electron path requiring four circuits to return.
- The study confirms that researchers can engineer tiny electron states and validate quantum behavior using IBM's quantum hardware, while experts say applications remain distant but may include quantum sensors, Igor Rončević said.
- Quantum hardware now models up to 32 electrons, reflecting a maturing role for quantum computers in chemistry, while commentators debate whether this shows clear quantum advantage.
