In Quantum Sensing, What Beats Beating Noise? Meeting Noise Halfway.
September 16, 2025
Qubits, the basic units of data for quantum computers, can be harnessed to work as quantum sensors, which could lead to better methods for navigation, resource exploration and timekeeping. Theoretical physicists have found a potential way to design groups of interlinked or “entangled” qubits to protect them from environmental disturbances or “noise” such as temperature changes. These entangled qubits would lose some of their potential sensitivity, but they would also be more robust against noise, making them a promising route to real-world quantum sensors.

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.

Anyone for Anyons?
February 13, 2025
Researchers have demonstrated that a strange type of quantum particle called the anyon, believed to exist in only two dimensions, can also be created in one dimension. Further studies exploring different types of one-dimensional anyons could bring scientists one step closer to using the particles as a fundamental unit of memory in a quantum computer.
