Abstract

In this chapter we present how real-time quantum subspace methods can be modified to simulate open quantum systems in Lindblad form. We apply these methods to a two-photon driven superconducting Kerr resonator and show how they allow to estimate the Liouvillian gap in the Kerr Cat qubit regime. This is based on work done between November 2025 and January 2026 and on the talk given in early February 2026 at the Kwekfest 2026 conference, to celebrate L.C. Kwek's lifetime achievements.
