Common Wifi can detect weapons, bombs and chemicals in bags — ScienceDaily

Ordinary WiFi can easily detect weapons, bombs and explosive chemicals in bags at museums, stadiums, theme parks, schools and other public venues, according to a Rutgers University-New Brunswick-led study. The researchers’ suspicious object detection system is easy to set up, reduces security screening costs and avoids invading privacy such as when screeners open and inspect bags, backpacks and luggage. Traditional ...

Researchers demonstrate fault-tolerant universal holonomic quantum gates — ScienceDaily

Researchers have demonstrated holonomic quantum gates under zero-magnetic field at room temperature, which will enable the realization of fast and fault-tolerant universal quantum computers. A quantum computer is a powerful machine with the potential to solve complex problems much faster than today’s conventional computer can. Researchers are currently working on the next step in quantum computing: building a universal quantum ...

System encourages government transparency using cryptography on a public log of wiretap requests — ScienceDaily

When the FBI filed a court order in 2016 commanding Apple to unlock the San Bernandino shooter’s iPhone, the news made headlines across the globe. Yet every day there are tens tens of thousands of of other court orders asking tech companies to turn over Americans’ private data. Many of these orders never see the light of day, leaving a ...

Researchers help close security hole — ScienceDaily

Cybersecurity researchers at the Georgia Institute of Technology have helped close a security vulnerability that could have allowed hackers to steal encryption keys from a popular security package by briefly listening in on unintended “side channel” signals from smartphones. The attack, which was reported to software developers before it was publicized, took advantage of programming that was, ironically, designed to ...
