Scientists generate 'first' stable qubits at room temperature

A team of researchers from Kyushu University's Faculty of Engineering, led by Associate Professor Nobuhiro Yanai, has shattered barriers by achieving quantum coherence at room temperature. Their study reveals the ability to maintain a well-defined quantum state, untouched by external disturbances, right here on Earth's surface.

The key to this discovery lies in the marriage of a chromophore—a light-absorbing dye molecule—and a metal-organic framework (MOF), a nanoporous crystalline material composed of metal ions and organic ligands.

"This is the first room-temperature quantum coherence of entangled quintets," stated Professor Kobori in a press release. Though the coherence is currently observed in nanoseconds, the findings lay the foundation for future quantum computing and sensing endeavors.
