Why Do We Need A Next Generation Of Terahertz Systems? In physics, terahertz radiation refers to electromagnetic waves propagating at frequencies in the terahertz range.The term typically applies to electromagnetic radiation with frequencies between high-frequency edge of the microwave band, 300 gigahertz (3×1011 Hz), and the long-wavelength edge of far-infrared light, 3000 GHz (3×1012 Hz or […]

What Is Unconventional Superconductivity? Superconductivity was discovered in Hg in 1911 by the group of Kamerling Onnes in Leiden (Holland). The mystery of superconductivity was, however, not uncovered until 1957 when Bardeen-Cooper-Schrieffer (BCS) proposed the electron-phonon coupling picture. In the BCS picture, two electrons near the Fermi surface with opposite momenta and spins will form […]

Impossible Applications for Today’s Parallel Processors, Possible With Quantum Computers. Researchers from Griffith University and the University of Queensland, Australia have overcome one of the key challenges to quantum computing by simplifying a complex quantum logic operation. They demonstrated this by experimentally realizing a challenging circuit namely the quantum Fredkin gate, for the first time.

This Bizarre Electron Behavior May Lead To New Electronic Technologies. Researchers at Princeton University have observed a bizarre behavior in a strange new crystal that could hold the key for future electronic technologies. Unlike most materials in which electrons travel on the surface, in these new materials the electrons sink into the depths of the crystal […]

A Mystery Around a Black Hole 5 billion Light-Years Away. A team of Spanish researchers, with the participation of the University of Granada (UGR), has accurately detected a structure in the innermost region of a quasar (small, very far objects that emit huge amounts of energy, comparable to that emitted by a whole galaxy) at […]

A Quantum Computer on the Horizon? Researchers at the University of Chicago’s Institute for Molecular Engineering and the University of Konstanz have demonstrated the ability to generate a quantum logic operation, or rotation of the qubit, that surprisingly is intrinsically resilient to noise as well as to variations in the strength or duration of the […]

Research into the particles produced by nuclear reactors. An international team that includes researchers from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has captured the most precise (and puzzling)energy measurements yet of ghostly particles called reactor antineutrinos produced at a nuclear power complex in China.

Lets Starting Working on A Space Based Gravitational Wave Observatory. Albert Einstein predicted the existence of gravitational waves in his general theory of relativity a century ago, and scientists have been attempting to detect them for 50 years. Einstein pictured these waves as ripples in the fabric of space-time produced by massive, accelerating bodies, such […]

Quantifying The Quantum State.  The interaction of thermal energy from the environment with motional degrees of freedom is well known and often referred to as Brownian motion (also thermal motion). But in the case of polar molecules, the internal degrees of freedom – in particular the rotational quantum state – are also influenced by the […]
