Latest Quantum cryptography Stories
A quantum particle is hard to grasp, because one cannot determine all its properties precisely at the same time.
A research group led by computer scientists at the UCLA Henry Samueli School of Engineering and Applied Science has proved that cryptography â€” the practice and study of hiding information â€” that is based solely on physical location is possible by using quantum mechanics.
Since Richard Feynman's first envisioned the quantum computer in 1982, there have been many studies of potential candidates -- computers that use quantum bits, or qubits, capable of holding an more than one value at a time and computing at speeds far beyond existing silicon-based machines for certain problems.
Any physical system - be it an electron, a molecule of water, a virus, a human being, a whole planet â€“ is characterized at each moment in time distinctively and specifically in a specific place by particular characteristics.
On Monday, Australian scientists unveiled the world's smallest electronic switch measuring just a few atoms, which will shrink microchips and revolutionize computing speeds.
There are enticing new findings this week in the worldwide search for materials that support fault-tolerant quantum computing.
Largest simulation of an ideal quantum computer; efficient multi-core software developed.
TAU scientist invents a digital security tool good enough for the CIA -- and for you.
A special issue of the Journal of Computer Security (IOS Press, ISSN 0926-227X) brings together the research results of six ongoing FP6-IST projects.
Diamond nanowire device could lead to new class of diamond nanomaterials suitable for quantum cryptography, quantum computing, and magnetic field imaging.
