High coherence 2D Kerr-cat qubit: Experimental realization and technical challenges

ORAL

Abstract

The Kerr-cat qubit is a bosonic qubit with promising potential to implement quantum error correction codes tailored for noise-biased qubits. Its intrinsic nonlinearities enable fast logic gates and QND measurements. However, since it is a strongly driven matter qubit it comes with many technical challenges when scaling to multi-qubit chips. In this talk, we present our experimental progress toward realizing large cat states with high coherence in 2D architectures paving the way for scalable multi-qubit operations.
