    New Protocol Demonstrates and Verifies Quantum Speedups in a Jiffy

    June 9, 2025

    Researchers at JQI and the University of Maryland (UMD) have discovered a new way to quickly check the work of a quantum computer. They proposed a novel method to both demonstrate a quantum device’s problem-solving power and verify that it didn’t make a mistake. They described their protocol in an article published March 5, 2025, in the journal PRX Quantum.

    New Design Packs Two Qubits into One Superconducting Junction

    October 21, 2024

    Quantum computers are the basis of a growing industry. However, their technology isn’t standardized yet, and researchers are still studying the physics that goes into quantum devices. Even the most basic building blocks of a quantum computer—qubits—are still an active research topic. In an article in the journal Physical Review A, JQI researchers proposed a way to use the physics of superconducting junctions to let each function as more than one qubit.

    Graphs May Prove Key in Search for Holy Grail of Quantum Error Correction

    October 24, 2022

    In February 2019, JQI Fellow Alicia Kollár, who is also an assistant professor of physics at UMD, bumped into Adrian Chapman, then a postdoctoral fellow at the University of Sydney, at a quantum information conference. Although the two came from very different scientific backgrounds, they quickly discovered that their research had a surprising commonality. They both shared an interest in graph theory, a field of math that deals with points and the connections between them. Their ensuing collaboration resulted in a new tool that aids in the search for new quantum error correction schemes—including the Holy Grail of self-correcting quantum error correction. They published their findings recently in the journal Physical Review X Quantum.
