Optical fibers fit for the age of quantum computing

A new generation of specialty optical fibers has been developed by physicists to cope with the challenges of data transfer expected to arise in the future age of quantum computing. more…

Mass layoffs and data breaches could be connected

A research team has been exploring how mass layoffs and data breaches could be connected. Their theory: since layoffs create conditions where disgruntled employees face added stress or job insecurity, they are more likely to engage in risky behaviors that heighten the company’s vulnerability to data breaches. more…

Mechanical computer relies on kirigami cubes, not electronics

Researchers have developed a kirigami-inspired mechanical computer that uses a complex structure of rigid, interconnected polymer cubes to store, retrieve and erase data without relying on electronic components. The system also includes a reversible feature that allows users to control when data editing is permitted and when data should be locked in place. more…

Breakthrough may clear major hurdle for quantum computers

The potential of quantum computers is currently thwarted by a trade-off problem. Quantum systems that can carry out complex operations are less tolerant to errors and noise, while systems that are more protected against noise are harder and slower to compute with. Now a research team has created a unique system that combats the dilemma, […] more…

Discovery highlights ‘critical oversight’ in perceived security of wireless networks

A research team has uncovered an eavesdropping security vulnerability in high-frequency and high-speed wireless backhaul links, widely employed in critical applications such as 5G wireless cell phone signals and low-latency financial trading on Wall Street. more…

VR may pose privacy risks for kids: A new study finds parents aren’t as worried as they should be

New research finds that, while an increasing number of minors are using virtual reality (VR) apps, not many parents recognize the extent of the security and privacy risks that are specific to VR technologies. The study also found that few parents are taking active steps to address those security and privacy issues, such as using […] more…

Computer scientists unveil novel attacks on cybersecurity

Researchers have found two novel types of attacks that target the conditional branch predictor found in high-end Intel processors, which could be exploited to compromise billions of processors currently in use. more…

This tiny chip can safeguard user data while enabling efficient computing on a smartphone

A new chip can efficiently accelerate machine-learning workloads on edge devices like smartphones while protecting sensitive user data from two common types of attacks — side-channel attacks and bus-probing attacks. more…

Breakthrough promises secure quantum computing at home

The full power of next-generation quantum computing could soon be harnessed by millions of individuals and companies, thanks to a breakthrough guaranteeing security and privacy. This advance promises to unlock the transformative potential of cloud-based quantum computing. more…

Protecting art and passwords with biochemistry

A new molecular test method helps to prove the authenticity of works of art. The new method could also help to make passwords secure against quantum computers. more…

100 kilometers of quantum-encrypted transfer

Researchers have taken a big step towards securing information against hacking. They have succeeded in using quantum encryption to securely transfer information 100 kilometers via fiber optic cable — roughly equivalent to the distance between Oxford and London. more…

Where quantum computers can score

The traveling salesman problem is considered a prime example of a combinatorial optimization problem. Now a team has shown that a certain class of such problems can actually be solved better and much faster with quantum computers than with conventional methods. more…

Satellites for quantum communications

Through steady advances in the development of quantum computers and their ever-improving performance, it will be possible in the future to crack our current encryption processes. To address this challenge, researchers are developing encryption methods that will apply physical laws to prevent the interception of messages. To safeguard communications over long distances, the QUICK space […] more…

A new design for quantum computers

Creating a quantum computer powerful enough to tackle problems we cannot solve with current computers remains a big challenge for quantum physicists. A well-functioning quantum simulator — a specific type of quantum computer — could lead to new discoveries about how the world works at the smallest scales. Quantum scientists have developed a guide on […] more…

Researchers unveil new way to counter mobile phone ‘account takeover’ attacks

Computer science researchers have developed a new way to identify security weaknesses that leave people vulnerable to account takeover attacks, where a hacker gains unauthorized access to online accounts. more…

Defending your voice against deepfakes

Computer scientists have developed AntiFake, a tool to protect voice recordings from unauthorized speech synthesis. more…
