Bosonic encoding is a promising approach for quantum information processing that aims to reduce hardware overhead by leveraging the many levels of a harmonic oscillator mode. Currently, scaling to multiple modes requires a delicate balance of weak interaction for independent control and strong interaction for fast control, posing a challenge for achieving fast and efficient universal control on multiple modes. In this presentation, I will introduce the circuit QED platform, which is considered a leading platform for quantum information processing, utilizing superconducting circuits. This platform boasts world record capabilities for both standard qubit encoding and bosonic encoding. I will then discuss our novel conditional not displacement control method, which enables fast operations yet with weak interaction, allowing generation, control, and correlator measurements of bosonic states in multi-mode systems. I will showcase how we create entangled and separable cat-states in different modes of a multi-mode cavity, demonstrating operations that are nearly two orders of magnitude faster than previous experiments. Finally, I will conclude with an outlook on the potential impact of our work, highlighting the advancements and opportunities for leveraging bosonic encoding.
