Entanglement—linking distant particles or groups of particles so that one cannot be described without the other—is at the core of the quantum revolution changing the face of modern technology.

While entanglement has been demonstrated in very small particles, new research from the lab of University of Chicago Pritzker School of Molecular Engineering (UChicago PME) Prof. Andrew Cleland is thinking big, demonstrating high-fidelity entanglement between two acoustic wave resonators.

The paper is published in Nature Communications.

Is DOGE a cybersecurity threat? A security expert explains the dangers of violating protocols and regulations

The Department of Government Efficiency (DOGE), President Donald Trump’s special commission tasked with slashing federal spending, continues to disrupt Washington and the federal bureaucracy. According to published reports, its teams are dropping into federal agencies with a practically unlimited mandate to reform the federal government in accordance with recent executive orders.

As a 30-year cybersecurity veteran, I find the activities of DOGE thus far concerning. Its broad mandate across government, seemingly nonexistent oversight, and the apparent lack of operational competence of its employees have demonstrated that DOGE could create conditions that are ideal for cybersecurity or data privacy incidents that affect the entire nation.

As 5G and 6G networks expand, they promise a future of incredibly fast and reliable wireless connections. A key technology behind this is millimeter-wave (mmWave), which uses very high-frequency radio waves to transmit huge amounts of data. To make the most of mmWave, networks use large groups of antennas working together, called massive Multiple-Input Multiple-Output (MIMO).

However, managing these complex antenna systems is challenging...

Self-powered sensor can generate electricity and light simultaneously using only movement

DGIST research teams have developed a self-powered sensor that uses motion and pressure to generate electricity and light simultaneously. This battery-free technology is expected to be used in various real-life applications, such as disaster rescue, sports, and wearable devices.

Triboelectric nanogenerators (TENG) and mechanoluminescence (ML) have attracted attention as green energy technologies that can generate electricity and light, respectively, without external power. However, researchers in previous studies mainly focused on the two technologies separately or simply combined them. Moreover, the power output stability of TENG and the insufficient luminous duration of ML materials have been major limitations for practical applications.
