Establishing the foundations for next-generation national competitiveness.

The Quantum Technology Institute carries out a broad range of R&D projects on novel measurement standard research fields for next-generation quantum computing, quantum communications, and quantum sensors. Additionally, the institute develops core quantum technologies with the goal of securing next-generation national competitiveness in the related fields.

Our institute develops methods to measure and control quantized physical quantities such as photons, atoms, electrons, and phonons, and to generate and control quantum mechanical effects such as qubits and quantum entanglement. Such quantum technologies can realize new measurement standards (Josephson voltage standard, quantum Hall resistance standard, optical lattice clock etc.), next-generation computing (quantum computers), secure cryptosystems (quantum key distribution), and ultra-high-sensitivity sensing and imaging (quantum sensors). We aim to develop key technologies and achieve research excellence to lay the foundations for new future-oriented industries that beat the classical limits.
