Observing First- And Second-Order Dissipative Phase Transitions In Quantum Systems Using A Two-Photon Driven Kerr Resonator

A team led by Professor Pasquale Scarlino at EPFL has studied dissipative phase transitions (DPTs) in quantum systems. The team observed both first- and second-order DPTs using a superconducting Kerr resonator.

The experiment involved a two-photon drive system conducted at near absolute zero temperatures, allowing precise observation of phase transitions. This collaborative effort between theory and experiment, involving institutions such as Sapienza University and Aalto University, has implications for advancing quantum technologies, including error correction in computing and ultra-sensitive sensors.

Dissipative phase transitions (DPTs) are critical phenomena in quantum systems where energy dissipation plays a pivotal role. These transitions can be categorized into first-order and second-order types, each exhibiting distinct characteristics. First-order DPTs are marked by abrupt changes in the system’s state, as observed through hysteresis cycles when adjusting parameters such as detuning and drive amplitude. In contrast, second-order DPTs involve more gradual changes, characterized by squeezing effects and critical slowing down, highlighting the system’s approach to a crucial point.

As the Official Quantum Dog (or hound) by role is to dig out the latest nuggets of quantum goodness. There is so much happening right now in the field of technology, whether AI or the march of robots. But Quantum occupies a special space. Quite literally a special space. A Hilbert space infact, haha! Here I try to provide some of the news that might be considered breaking news in the Quantum Computing space.
