- Exchanging information securely using quantum communication in future fiber-optic networks February 28, 2019
Searching for better security during data transmission, governments and other organizations around the world have been investing in and developing technologies related to quantum communication and related encryption methods. Researchers are looking at how these new systems — which, in theory, would provide unhackable communication channels — can be integrated into existing and future fiber-optic […]
- Safeguarding hardware from cyberattack February 27, 2019
Researchers have developed an algorithm that safeguards hardware from attacks designed to steal data. In the attacks, hackers detect variations of power and electromagnetic radiation in an electronic device's hardware and use the variation to steal encrypted information.
- 'Immunizing' quantum bits so that they can grow up February 26, 2019
Qubits need a better immune system before they can grow up. A new material, engineered into a thin strip, is one step closer to 'immunizing' qubits against noise, such as heat and other parts of a computer, that interferes with how well they hold information.
- Most laptops vulnerable to attack via peripheral devices February 26, 2019
Many modern laptops and an increasing number of desktop computers are much more vulnerable to hacking through common plug-in devices than previously thought, according to new research.
- Entangling photons of different colors February 25, 2019
Researchers have developed a novel way to entangle two photons — one with a wavelength suitable for quantum-computing devices and the other for fiber-optics transmissions.
- Faster method to read quantum memory February 25, 2019
Scientists have developed a faster way to read information out of qubits, the basic building blocks of a quantum computer.
- Researchers unveil Internet of Things security feature February 20, 2019
Integrated circuit designers have developed a new approach for creating secure keys and IDs on Internet of Things (IoT).
- Altered data sets can still provide statistical integrity and preserve privacy February 17, 2019
Synthetic networks may increase the availability of some data while still protecting individual or institutional privacy, according to a statistician.
- Quantifying how much quantum information can be eavesdropped January 28, 2019
The most basic type of quantum information processing is quantum entanglement. Researchers have now provided a much finer characterization of the distributions of entanglement in multi-qubit systems than previously available. These findings can be used in quantum cryptography to estimate the quantity of information an eavesdropper can capture regarding the secret encryption key.
- Better safeguards for sensitive information January 28, 2019
Despite being the most advanced quantum technology, secure encryption of information units based on a method called quantum key distribution (QKD) is currently limited by the channel's capacity to send or share secret bits. Scientists now show how to better approach the secret key capacity by improving the channel's lower boundary.
