- Abstract: The motivation for observing quantum superposition in macroscopic systems guided us to the research of superconducting quantum circuits and the realization of superconducting qubits. The qubit itself is a many-body system of interacting electrons designed and fabricated in the form of an electrical circuit, where quantized energy levels of a collective excitation mode are used as the bases for storing and manipulating quantum information. With the strong nonlinearity due to the Josephson effect and the large dipole moments that allow fast control and readout of the quantum states, superconducting qubits comprise versatile platforms for quantum information processing. Now, having accumulated knowledge and technology, we are facing new challenges in constructing an artificial quantum system with a macroscopic number of qubits and controlling them precisely. We will discuss our approach at RIKEN.
