Non-reciprocal circuit quantum electrodynamics with ferrites
Abstract
The general objective of the proposed project is to create and demonstrate a fully-functional cQED device (a coherent cavity-qubit coupled system with universal quantum control and readout) that includes nonreciprocal interaction between two or more of its internal quantum components. To realize such a device, much of the effort will be focused on a critical intermediate goal of engineering a directional transmission channel, i.e. a directional quantum bus, between two localized qubit or cavity modes. As an important application of the proposed non-reciprocal cQED, we envision a cQED device architecture composed of quantum modules with hierarchies, where a lower-tier (ÔchildÕ) module can transfer its quantum state to an upper-tier (ÔparentÕ) module with high fidelity while maintaining excellent reverse isolation. In this proposal, we will aim to demonstrate a block of this architecture and realize directional quantum state transfer between modules.
