World’s first hybrid quantum supercomputer Reimei activated in Japan

Japan has activated Reimei, the world's first operational hybrid quantum supercomputer. The 20-qubit quantum machine is integrated into Fugaku, the sixth-fastest supercomputer globally. Reimei uses trapped-ion qubits, offering advantages in stability and control. The system employs advanced error correction techniques, grouping physical qubits into more stable "logical qubits." This quantum-supercomputer integration aims to solve complex problems in physics and chemistry much faster than traditional supercomputers, potentially reducing calculation times dramatically.
