Topic: qubits

Design and characterize qubits for integrated circuits within the Moonshot project on fault-tolerant superconducting quantum computing. Research also covers quantum electronics and hybrid quantum systems. 1.A one-year fixed-term employment contract, renewable based on evaluation, up to March 31, 2031 from the date of hire. 2.RIKEN may adjust the above maximum period of renewability based on a) the employee’s abilities, workload at the time of contract completion, performance and work attitude and b) the continuation of the employee’s center, laboratory or project and RIKEN’s management situati

Sisi Zhou examines how quantum information methods can improve the precision of physical measurements. Qubit examples distinguish noise that quantum error correction can suppress from noise indistinguishable from the signal. The discussion extends to several qubits, phase estimation, many-body measurements and distributed sensors. A second part applies quantum-learning tools, including tomography, certification and purification, to estimation of several parameters. Because incompatible observables prevent all parameters from being measured optimally together, designing measurements is difficul
