Landmark Study Discovers Magnetic Properties of Phonons

Landmark Study Discovers Magnetic Properties of Phonons

Phonons--the elemental particles that transmit both heat and sound--have magnetic properties, according to a landmark study supported by Ohio Supercomputer Center (OSC) services and recently published by a researcher group from The Ohio State University. [More]

Different Parity Check Gates Enable Efficient N-Particle W State Concentration

Entanglement is an important quantum resource in both quantum communication and computation. The applications of entanglement information processing such as quantum teleportation, quantum key distribution (QKD), quantum dense coding, quantum secret sharing (QSS), and quantum secure direct communication (QSDC) all resort the entanglement to set up the quantum channel between long distant locations.

Big Bang Theory Scholarship Endowment Raises Over $4 Million for STEM Students

A co-creator and the cast and crew of the hit television show “The Big Bang Theory” have endowed a scholarship fund at UCLA to provide financial aid to undergraduate students pursuing degrees in science, technology, engineering and mathematics fields. [More]
Quantum Process Tomography Helps Characterize Unknown Quantum Processes

Quantum Process Tomography Helps Characterize Unknown Quantum Processes

Scientists and engineers from the University of Bristol, UK, and the Centre for Quantum Technologies in Singapore have published work in the June issue of Optica. They demonstrate a new protocol for estimating unknown optical processes, called unitary operations, with precision enhanced by the unique properties of quantum mechanics. This could lead to both dramatically better sensors for medical research and new approaches to benchmark the performance ultra-powerful quantum computers. [More]

Astrophysicists Probe Effect of Rayleigh Scattering on the Cosmic Microwave Background

Astrophysicists have developed a new method for calculating the effect of Rayleigh scattering on photons, potentially allowing researchers to better understand the formation of the Universe. [More]
X-Ray and Gamma-Ray Observations Set Limits on Quantum Nature of Space-Time at Extremely Tiny Scales

X-Ray and Gamma-Ray Observations Set Limits on Quantum Nature of Space-Time at Extremely Tiny Scales

A team of scientists has used X-ray and gamma-ray observations of some of the most distant objects in the Universe to better understand the nature of space and time. Their results set limits on the quantum nature, or “foaminess” of space-time at extremely tiny scales. [More]
Optical Data Transport for Faster Computers and Ultra-Secure Quantum Communications

Optical Data Transport for Faster Computers and Ultra-Secure Quantum Communications

Stanford electrical engineer Jelena Vuckovic wants to make computers faster and more efficient by reinventing how they send data back and forth between chips, where the work is done. [More]
Donut Hole May Holds Answers for More Efficient, Reliable Quantum Information Teleportation

Donut Hole May Holds Answers for More Efficient, Reliable Quantum Information Teleportation

Putting a hole in the center of the donut--a mid-nineteenth-century invention--allows the deep-fried pastry to cook evenly, inside and out. As it turns out, the hole in the center of the donut also holds answers for a type of more efficient and reliable quantum information teleportation, a critical goal for quantum information science.

Supermassive Black Holes That Power Radio-Signal-Emitting Jets Linked to Merger History of Host Galaxies

Supermassive Black Holes That Power Radio-Signal-Emitting Jets Linked to Merger History of Host Galaxies

In the most extensive survey of its kind ever conducted, a team of scientists have found an unambiguous link between the presence of supermassive black holes that power high-speed, radio-signal-emitting jets and the merger history of their host galaxies. Almost all of the galaxies hosting these jets were found to be merging with another galaxy, or to have done so recently. The results lend significant weight to the case for jets being the result of merging black holes and will be presented in the Astrophysical Journal. [More]
Researchers Demonstrate Peculiarity of One-Dimensional Quantum Systems

Researchers Demonstrate Peculiarity of One-Dimensional Quantum Systems

A quantum system never relaxes. An isolated system (like a cloud of cold atoms trapped in optical grids) will endlessly oscillate between its different configurations without ever finding peace. In practice, these types of systems are unable to dissipate energy in any form. This is the exact opposite of what happens in classical physics, where the tendency to reach a state of equilibrium is such a fundamental drive that is has been made a fundamental law of physics, i.e., the second law of thermodynamics, which introduces the concept of entropy.
