EPFL researchers have experimentally observed both first- and second-order dissipative phase transitions (DPTs) in a superconducting Kerr resonator. By introducing a two-photon drive, they precisely controlled quantum state transitions, revealing phenomena like squeezing, hysteresis, and critical slowing down.
Their findings confirm theoretical predictions and enhance understanding of quantum systems. This breakthrough could lead to improved quantum computing error correction and ultra-sensitive quantum sensors. The study highlights the power of interdisciplinary collaboration, merging experimental physics, theory, and engineering to push the boundaries of quantum science.
