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...

Wormholes Driving Quantum Entanglement
2013-12-04 15:25:47

John P. Millis, PhD for redOrbit.com - Your Universe Online One of the strangest consequences of quantum theory, is what happens when elementary particles are created in pairs. These individual charges become entangled with their counterparts. The result is that interactions with one of these particles creates direct consequences for the other, even if the other particle is on the other side of the Universe. The simplest example of this is when an electron and positron are created when...

Decay Used To Create Quantum Information
2013-11-25 09:47:26

University of Copenhagen - Niels Bohr Institute Usually, when researchers work with quantum information, they do everything they can to prevent the information from decaying. Now researchers at the Niels Bohr Institute, among others, have flipped things around and are exploiting the decay to create the so-called entanglement of atomic systems, which is the foundation for quantum information processing. The results are published in the scientific journal, Nature. "When working with...

A quantum computer can solve tasks where a classical computer fails. The question how one can, nevertheless, verify the reliability of a quantum computer was recently answered in an experiment at the University of Vienna. The conclusions are published in the reputed scientific journal Nature Physics. The harnessing of quantum phenomena, such as superposition and entanglement, holds great promise for constructing future supercomputers using quantum technology. One huge advantage of such...

Transfer Of Flying Quantum Bits At The Touch Of A Button

Johannes Gutenberg Universitaet Mainz Hybrid technology makes possible highly reliable transmission of photonic qubits By means of the quantum-mechanical entanglement of spatially separated light fields, researchers in Tokyo and Mainz have managed to teleport photonic qubits with extreme reliability. This means that a decisive breakthrough has been achieved some 15 years after the first experiments in the field of optical teleportation. The success of the experiment conducted in Tokyo...

An Infallible Quantum Measurement
2013-08-05 10:10:55

AlphaGalileo Foundation For quantum physicists, entangling quantum systems is one of their every day tools. Entanglement is a key resource for upcoming quantum computers and simulators. Now, physicists in Innsbruck/Austria and Geneva/Switzerland realized a new, reliable method to verify entanglement in the laboratory using a minimal number of assumptions about the system and measuring devices. Hence, this method witnesses the presence of useful entanglement. Their findings on this...

Detection Of Single Photons Through Quantum Entanglement
2013-07-08 10:47:20

University of Innsbruck Almost 200 years ago, Bavarian physicist Joseph von Fraunhofer discovered dark lines in the sun's spectrum. It was later discovered that these spectral lines can be used to infer the chemical composition and temperature of the sun's atmosphere. Today we are able to gain information about diverse objects through light measurements in a similar way. Because often very little light needs to be detected for this, physicists are looking for ever more sensitive...

JQI lab sets a new record for creating heralded photons HERALDING Entanglement, by general consensus of physicists, is the weirdest part of quantum science. To say that two particles, A and B, are entangled means that they are actually two parts of an inseparable quantum thing. An important consequence of this inherent kinship is that measuring a property of A (say, the particle's polarization) is necessarily to know the corresponding property of B, even if you're not there with a...

Quantum Internet Prototype In Use At Los Alamos

Brett Smith for redOrbit.com - Your Universe Online As concerns over cyber security grow with each newly publicized attack, computer scientists have been pursuing quantum technology as a silver bullet against would-be hackers. According to a groundbreaking announcement, scientists at Los Alamos National Labs in New Mexico have been utilizing a small-scale “quantum internet” for the past two years. Quantum cryptography is possible because of the phenomenon known as quantum...
