"Superconducting Circuits for Quantum Information Processing:
How Electric Circuits Behave Quantum Mechanically"

Superconducting Circuits for Quantum Information Processing
Yasunobu Nakamura
Research Center for Advanced Science and technology (RCAST), The University of Tokyo
Center for Emergent Matter Science (CEMS), RIKEN


Abstract:
We all benefit from the amazing technologies of silicon large-scale integrated circuits (Si LSI) in our mobile phones, tablets, PCs, etc. It is almost incredible that billions of nanometer-scale transistors in a processor operate synchronously with a nanosecond clock cycle. Indeed, the emergence of the silicon empire in the last century is one of the biggest achievements of quantum mechanics and solid-state physics based on it. Nevertheless, circuit engineers are never bothered with quantum mechanics: While the dynamics of individual electrons can only be understood in the quantum languages, the operations of the devices are described fully classically, i.e., either ON or OFF. In contrast, superconducting circuits with a proper design can behave quantum mechanically in a macroscopic scale: Superposition of ON and OFF states is allowed in the quantum bit devices. I will discuss how to integrate such quantum bits and how to control and measure the quantum states toward realizing a superconducting quantum information processor.

"Simulating Quantum Behaviour with Quantum Computers"
Simulating quantum behaviour with quantum computers
Richard Cleve
University of Waterloo



Abstract:
In 1982, Richard Feynman proposed the concept of a quantum computer as a means of simulating physical systems that evolve according to the Schrödinger equation. Since that time, a rich theory of quantum computing has developed, which includes quantum algorithms for simulating physical systems (as well as for several other computing problems).

I will explain various quantum algorithms that have been proposed for Feynman's simulation problem, including my recent work (jointly with Dominic Berry and Rolando Somma) that dramatically improves the running time as a function of the precision of the output data.

"Make It Small and Take It Outside!"
Make it small and take it outside!
Alexander Ling
Centre for Quantum Technologies, NUS


Abstract:
Quantum physics allows us to model the behavior of matter and energy at the atomic and molecular level (and even beyond!) with a very high precision. Unfortunately, the devices needed to control and observe these quantum effects are often large and unwieldy, making the deployment of quantum-inspired technology a serious challenge. At the Centre for Quantum Technologies there is a program called the Small Photon-Entangling Quantum System that seeks to build and deploy complete entangled photon generators/detectors that have a small physical footprint. These devices are designed to operate autonomously in remote nodes of quantum communication networks. An example would be nanosatellites in low earth orbit. I will present the key design parameters that have enabled us to reduce the resource requirements and will discuss the outlook for experiments and applications.


7.30pm: End of Symposium
