Quantum: Calculating error-free more easily with two codes

Various methods are used to correct errors in quantum computers. Not all operations can be implemented equally well with different correction codes. Therefore, a research team has developed a method and implemented it experimentally for the first time, with which a quantum computer can switch back and forth between two correction codes and thus perform […] more…

Record cold quantum refrigerator paves way for reliable quantum computers

Quantum computers require extreme cooling to perform reliable calculations. One of the challenges preventing quantum computers from entering society is the difficulty of freezing the qubits to temperatures close to absolute zero. Now, researchers have engineered a new type of refrigerator that can autonomously cool superconducting qubits to record low temperatures, paving the way for […] more…

A new paradigm for control of quantum emitters

A research team developed a new paradigm for the control of quantum emitters, providing a new method for modulating and encoding quantum photonic information on a single photon light stream. more…

New security protocol shields data from attackers during cloud-based computation

Researchers developed a technique guaranteeing that data remain secure during multiparty, cloud-based computation. This method, which leverages the quantum properties of light, could enable organizations like hospitals or financial companies to use deep learning to securely analyze confidential patient or customer data. more…

Preventing counterfeiting by adding dye to liquid crystals to create uncrackable coded tags

A research group has developed an innovative approach to creating anti-counterfeiting labels for high-value goods. Their findings enhance the security of the currently used cholesteric liquid crystals (CLCs) by adding fluorescent dyes to produce florescent CLCs (FCLCs). Using this unique technology, the group created unique labels with almost impossible-to-counterfeit security features. These advanced labels are […] more…

Building on a landmark algorithm, researchers propose a way to make a smaller and more noise-tolerant quantum factoring circuit for cryptography. more…

Physicists develop new method to combine conventional internet with the quantum internet

Researchers send entangled photons and laser pulses of the same color over a single optical fiber for the first time. more…

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…
