  • Abstract

  • Last two decades were amazingly exciting time for quantum technologies. Never before mankind has had more control on quantum states than today and now we expect that the realization of a quantum “computer” might not be that too far. Among many candidate quantum platforms, the superconducting circuit (yes, circuits!) is now considered as the most promising one for building a scalable quantum computer. In this short talk, I will briefly review recent developments in the field of (mostly superconducting, but not limited to) quantum computing research. I will briefly present (my personal view of) the past, now and future of the quantum computing technology development. For the technical part of the talk, I will introduce our current activities in KRISS. I will explain how to make a qubit (quantum bit) out of a superconducting circuit element called Josephson junction. Quantum state manipulation and measurement of a qubit will be shown, together with how to evaluate quantum operations’ fidelity.
