New Steganography Breakthrough Enables “Perfectly Secure” Digital Communications

New Steganography Breakthrough Enables “Perfectly Secure” Digital Communications

Researchers have achieved a breakthrough to enable ‘perfectly secure’ hidden communications for the first time.
The method uses new advances in information theory methods to conceal one piece of content inside another in a way that cannot be detected.
This may have strong implications for information security, besides further applications in data compression and storage.

Quantum Computing Breakthrough: Silicon Encoded Spin Qubits Achieve Universality

Quantum Computing Breakthrough: Silicon Encoded Spin Qubits Achieve Universality

HRL Laboratories, LLC, has published the first demonstration of universal control of encoded spin qubits. This newly emerging approach to quantum computation uses a novel silicon-based qubit device architecture, fabricated in HRL’s Malibu cleanroom, to trap single electrons in quantum dots. Spins of three such single electrons host energy-degenerate qubit states, which are controlled by nearest-neighbor contact interactions that partially swap spin states with those of their neighbors.

1000x Faster: World’s Fastest Laser Camera Films Combustion in Real Time

By illuminating a sample surface with short laser beam pulses, it is possible to film sequences of various chemical and physical reactions. A research team that included researchers from the University of Gothenburg has now developed the world’s fastest single-shot laser camera, which is at least a thousand times faster than today’s most modern equipment for combustion diagnostics. The discovery has enormous significance for studying the lightning-fast combustion of hydrocarbons.
