Hybrid quantum systems based on collective excitations in solid
  AlbaNova and Nordita Colloquium

Thursday 03 October 2019
from 15:00 to 17:00
Speaker : Yasunobu Nakamura (RIKEN, Tokyo University)
Abstract : Development of superconducting quantum circuit technology manifests our ability to control and measure quantum states of the collective excitation modes in a circuit. The approach can be extended to many other collective modes found in solid-state physics, allowing us to access single quanta of those excitations, especially by using superconducting qubits as a tool. We discuss the examples in quantum magnonics [1-3] and quantum acoustics [4-6]. [1] Y. Tabuchi et al., Science 349, 405 (2015). [2] D. Lachance-Quirion et al., Sci. Adv. 3, e1603150 (2017). [3] D.
