Researchers discover more efficient way to route information in quantum computers

Quantum computers have the potential to revolutionize computing by solving complex problems that stump even today’s fastest machines. Scientists are exploring whether quantum computers could one day help streamline global supply chains, create ultra-secure encryption to protect sensitive data against even the most powerful cyberattacks, or even develop more effective drugs by simulating their behavior at the atomic level.

But building efficient quantum computers isn’t just about developing faster chips or better hardware. It also requires a deep understanding of quantum mechanics—the strange rules that govern the tiniest building blocks of our universe, such as atoms and electrons—and how to effectively move information through .

In a paper published in Physics Review X, a team of physicists—including graduate student Elizabeth Champion and assistant professor Machiel Blok from the University of Rochester’s Department of Physics and Astronomy—outlined a method to address a tricky problem in quantum computing: how to efficiently move information within a multi-level system using quantum units called qudits.

NightEagle APT Exploits Microsoft Exchange Flaw to Target China’s Military and Tech Sectors

Cybersecurity researchers have shed light on a previously undocumented threat actor called NightEagle (aka APT-Q-95) that has been observed targeting Microsoft Exchange servers as a part of a zero-day exploit chain designed to target government, defense, and technology sectors in China.

According to QiAnXin’s RedDrip Team, the threat actor has been active since 2023 and has switched network infrastructure at an extremely fast rate. The findings were presented at CYDES 2025, the third edition of Malaysia’s National Cyber Defence & Security Exhibition and Conference held between July 1 and 3, 2025.

Over 40 Malicious Firefox Extensions Target Cryptocurrency Wallets, Stealing User Assets

Cybersecurity researchers have uncovered over 40 malicious browser extensions for Mozilla Firefox that are designed to steal cryptocurrency wallet secrets, putting users’ digital assets at risk.

“These extensions impersonate legitimate wallet tools from widely-used platforms such as Coinbase, MetaMask, Trust Wallet, Phantom, Exodus, OKX, Keplr, MyMonero, Bitget, Leap, Ethereum Wallet, and Filfox,” Koi Security researcher Yuval Ronen said.

The large-scale campaign is said to have been ongoing since at least April 2025, with new extensions uploaded to the Firefox Add-ons store as recently as last week.
