Researchers from Osaka University fabricated copolymers with chiral backbones based on indacenodithiophene. Spin-coated films of the copolymers behaved differently toward currents with opposite polarization, resulting in chirality-induced spin selectivity. The magnitude of this selectivity was quantified as a spin polarization of almost 70%, which is among the highest achieved to date for a chiral polymer. These chiral copolymer films are attractive for use as spin filters in spintronics applications.

Researchers from Osaka University found that how well light-converting molecules stack together in a solid is important for how well they convert light into electric current. A rigid molecule that stacked well showed excellent electricity generation in an organic solar cell and photocatalyst, easily outperforming a similar flexible molecule that did not stack well. This new way of improving the design of molecules could be used to pioneer the next generation of light-converting devices.

Fujitsu and Osaka University’s Center for Quantum Information and Quantum Biology (QIQB) today revealed the development of a new, highly efficient analog rotation quantum computing architecture, representing a significant milestone toward the realization of practical quantum computing. The new architecture reduces the number of physical qubits required for quantum error correction – a prerequisite for the realization of fault-tolerant quantum computing – by 90% from 1 million to 10,000 qubits. This breakthrough will allow research to embark on the construction of a quantum computer with 10,000 physical qubits and 64 logical qubits (4), which corresponds to computing performance of approximately 100,000 times that of the peak performance of conventional high performance computers.
