Quantum Physics May Make Secure, Single-use Computer Memories
2014-01-16 14:47:31

National Institute of Standards and Technology (NIST) Computer security systems may one day get a boost from quantum physics, as a result of recent research from the National Institute of Standards and Technology (NIST). Computer scientist Yi-Kai Liu has devised away to make a security device that has proved notoriously difficult to build—a "one-shot" memory unit, whose contents can be read only a single time. The research, which Liu is presenting at this week's Innovations in...

NSA Builds Encryption Busting Super Computer
2014-01-03 11:20:30

Peter Suciu for redOrbit.com – Your Universe Online On Thursday The Washington Post reported that the National Security Agency (NSA) is now developing a computer that, if successful, could break into nearly every type of encryption that currently exists. This would include encryption programs used to protect banking, medical, business and government records throughout the world. The Washington Post attributes these findings to documents provided by former NSA contractor Edward...

Popular television shows such as “Doctor Who” have brought the idea of time travel into the vernacular of popular culture. But problem of time travel is even more complicated than one might think. LSU’s Mark Wilde has shown that it would theoretically be possible for time travelers to copy quantum data from the past. It all started when David Deutsch, a pioneer of quantum computing and a physicist at Oxford, came up with a simplified model of time travel to deal with the paradoxes...

Quantum World Record Crushed
2013-11-14 15:37:00

University of Oxford A normally fragile quantum state has been shown to survive at room temperature for a world record 39 minutes, overcoming a key barrier towards building ultrafast quantum computers. An international team including Stephanie Simmons of Oxford University, UK, report in this week's Science a test performed by Mike Thewalt of Simon Fraser University, Canada, and colleagues. In conventional computers data is stored as a string of 1s and 0s. In the experiment quantum bits...

Study Provides Unprecedented Details On Ultrafast Processes In Diamond Nitrogen Vacancy Centers
2013-11-04 16:26:12

Lawrence Berkeley National Laboratory From supersensitive detections of magnetic fields to quantum information processing, the key to a number of highly promising advanced technologies may lie in one of the most common defects in diamonds. Researchers at the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley have taken an important step towards unlocking this key with the first ever detailed look at critical ultrafast processes in these...

A breakthrough in quantum cryptography demonstrates that information can be encrypted and then decrypted with complete security using the combined power of quantum theory and relativity - allowing the sender to dictate the unveiling of coded information without any possibility of intrusion or manipulation. Scientists sent encrypted data between pairs of sites in Geneva and Singapore, kept "perfectly secure" for fifteen milliseconds - putting into practice what cryptographers call a 'bit...

Like any task, there is an easy and a hard way to control atoms and molecules as quantum systems, which are driven by tailored radiation fields. More efficient methods for manipulating quantum systems could help scientists realize the next generation of technology by harnessing atoms and molecules to create small but incredibly powerful devices such as molecular electronics or quantum computers. Of course, controlling quantum systems is as painstaking as it sounds, and requires scientists...

Google Uses qCraft To Teach Quantum Physics
2013-10-21 10:47:40

Michael Harper for redOrbit.com - Your Universe Online Google released a new mod for the popular building game Minecraft over the weekend which aims to teach players the most basic aspects of quantum physics. Called “qCraft,” the Google mod (modification) is less of a full-blown quantum physics simulator and more of a introductory course. While exploring in this new area of the video game, players can experiment with concepts like quantum entanglement, superposition and observer...

In mathematics and computer science, an algorithm is a step-by-step procedure for calculations. Algorithms are used for calculations, automated reasoning, and data processing. An algorithm is an effective technique expressed as a finite list of well-defined instructions for calculating a function. Starting from an initial state and an initial input, the instructions describe a computation that, when executed, proceeds through a finite number of well-defined successive states and eventually...

Word of the Day
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
