Our research group is devoted to developing novel devices for quantum computing and communications. To build reliable quantum devices, we apply various device technologies to control waves and quantum bits (qubits). We engineer phonons and photons as well as on-chip quantum bits such as electron spin and single photons. Implementation of such functionality requires interdisciplinary approach, where the knowledge of traditional device technologies such as micro-electromechanical systems (MEMS), integrated photonics and quantum physics are uniquely combined.
Quantum computing with integrated photonics
To fully harness the exponential power of quantum computer, it needs to be a fault-tolerant one with a large number of qubits. Photonic quantum computing is a promising approach to achieve this goal due to its potential in scalability. We design integrated photonic circuits to build a useful quantum computer beyond noisy intermediate-scale quantum (NISQ) era. Read more at Research.
Spin quantum memory control via acoustic wave
Quantum computer and network need reliable quantum memories of a long lifetime. Electron spin qubits within artificial atom trapped in solid is a good candidate, however, its operation has been challenging. We take a novel approach that uses acoustic wave for its control. Read more at Research.
