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

…Matthew Viljoen explains qubits, superposition, entanglement and the transition from classical binary logic to quantum algorithms. Attila Csaba Marosi surveys quantum-hardware types, architectures and practical capabilities, mapping systems available in Europe and beyond. An open discussion considers how infrastructure operators, developers and domain scientists can prepare hybrid classical–quantum workflows within the EGI Federation’s 2026–2030 strategy.

…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

…For qubits, the resulting estimate is optimal up to a constant factor.
