Room-temperature quantum coherence of entangled multiexcitons in a metal-organic framework

Singlet fission (SF) can generate an exchange-coupled quintet triplet pair state 5TT, which could lead to the realization of quantum computing and quantum sensing using entangled multiple qubits even at room temperature. However, the observation of the quantum coherence of 5TT has been limited to cryogenic temperatures, and the fundamental question is what kind of material design will enable its room-temperature quantum coherence. Here we show that the quantum coherence of SF-derived 5TT in a chromophore-integrated metal-organic framework (MOF) can be over hundred nanoseconds at room temperature. The subtle motion of the chromophores in ordered domains within the MOF leads to the enough fluctuation of the exchange interaction necessary for 5TT generation, but at the same time does not cause severe 5TT decoherence. Furthermore, the phase and amplitude of quantum beating can be controlled by molecular motion, opening the way to room-temperature molecular quantum computing based on multipl..., , , # Title of Dataset
