Junior Quantum Seminar - Superconducting quantum technologies towards fault-tolerant quantum computing

Please join us for the Junior Quantum Seminar with Shingo Kono from the Laboratory of Photonic Integrated Circuits and Quantum Measurements at EPFL , who will give the talk "Superconducting quantum technologies towards fault-tolerant quantum computing " on Tuesday November 26. 
Location: CE 1 104.

Breakfast will be available before the seminar at 9:30. All PhDs, postdocs and students are welcome to join us.

ABTRACT:
 Superconducting quantum circuits represent a leading platform for large-scale quantum computing. Despite recent demonstrations of small sections of the surface code and claims of quantum supremacy, scaling current technologies to achieve fault tolerance remains a significant challenge. In this talk, I will introduce three distinct approaches to overcome the challenge. First, I will present novel qubit control and readout schemes using advanced quantum filters, which would offer power-efficient and scalable qubit operation protocols. Second, I will discuss our recent demonstrations of long-lived transmon qubits with > 0.5 ms, along with the discovery of a new error mechanism caused by mechanical shocks. Finally, I will introduce novel superconducting circuit optomechanics, positioning it as a promising candidate for long-lived and scalable quantum memory for superconducting quantum computing. 

BIO: 
Shingo Kono is currently a postdoctoral scholar at EPFL in the group of Tobias Kippenberg from 2021. His current research focuses on superconducting quantum circuits including superconducting qubits, circuit optomechanical devices, and Josephson parametric amplifiers. He obtained his PhD at the University of Tokyo under the supervision of Yasunobu Nakamura in 2019, working on quantum measurement of itinerant microwave photons. Then, he joined the Superconducting Quantum Electronics group led by Yasunobu Nakamura at RIKEN, working on waveguide quantum electrodynamics until 2020.
