    Repurposing Qubit Tech to Explore Exotic Superconductivity

    November 19, 2024

    The established knowledge and technical infrastructure from decades of quantum research are allowing researchers to harness quantum technologies in unexpected, innovative ways and creating new research opportunities. In a paper published in the journal Nature Physics, a collaboration between theorists at JQI and experimentalists at Harvard University presented a technique that repurposes the technology of superconducting circuits to study samples with exotic forms of superconductivity. The collaboration demonstrated that by building samples of interest into a superconducting circuit they could spy on exotic superconducting behaviors that have eluded existing measurement techniques.

    A Focused Approach Can Help Untangle Messy Quantum Scrambling Problems

    April 4, 2024

    The world is a cluttered, noisy place, and the ability to effectively focus is a valuable skill. Researchers at JQI have identified a new way to focus their attention and obtain useful insights into the way information associated with a configuration of interacting particles gets dispersed and effectively lost over time. Their technique focuses on a single feature that describes how various amounts of energy can be held by different configurations a quantum system. The approach provides insight into how a collection of quantum particles can evolve without the researchers having to grapple with the intricacies of the interactions that make the system change over time.

    Embracing Uncertainty Helps Bring Order to Quantum Chaos

    September 27, 2023

    In physics, chaos is something unpredictable. A butterfly flapping its wings somewhere in Guatemala might seem insignificant, but those flits and flutters might be the ultimate cause of a hurricane over the Indian Ocean. The butterfly effect captures what it means for something to behave chaotically: Two very similar starting points—a butterfly that either flaps its wings or doesn’t—could lead to two drastically different results, like a hurricane or calm winds. But there's also a tamer, more subtle form of chaos in which similar starting points don’t cause drastically different results—at least not right away. This tamer chaos, known as ergodicity, is what allows a coffee cup to slowly cool down to room temperature or a piece of steak to heat up on a frying pan. It forms the basis of the field of statistical mechanics, which describes large collections of particles and how they exchange energy to arrive at a shared temperature. Chaos almost always grows out of ergodicity, forming its most eccentric variant.
