Physicists' finding could revolutionize information transmission

A research team has observed, characterized, and controlled dark trions in a semiconductor -- ultraclean single-layer tungsten diselenide -- a feat that could increase the capacity and alter the form of information transmission.

Characterizing the 'arrow of time' in open quantum systems

Even in the strange world of open quantum systems, the arrow of time points steadily forward -- most of the time. New experiments compare the forward and reverse trajectories of superconducting circuits called qubits, and find that they largely tend to follow the second law of thermodynamics.

Physicists' finding could revolutionize information transmission

Move aside, electrons; it's time to make way for the trion.

'Connecting the dots' for quantum networks

Researchers have developed a novel technique that could enable new technologies that use properties of quantum physics for computing, communication and sensing, which may lead to 'neuromorphic' or brain-inspired computing.

Quantum chemistry on quantum computers

A new quantum algorithm has been implemented for identifying important physical quantities such as spin quantum numbers relevant to convoluted electronic wave functions on quantum computers, serving as tracking complex chemical reactions without exponential/combinatorial explosion, giving exact solutions of Schroedinger Equations for chemistry, for the first time.

On-demand control of terahertz and infrared waves

A theory from 2006 predicts that it should be possible to use graphene in a magnetic field not only to absorb terahertz and infrared light on demand but also to control the direction of the circular polarization. Researchers have succeeded in testing this theory and achieved the predicted results. The study shows that the scientists found an efficient way to control infrared and terahertz waves.

MEMS-in-the-lens architecture for laser scanning microscopy

Laser-scanning microscopes can be miniaturized to image microenvironments in vivo via inclusion inside optical micromechanical system (MEMS) devices to replace the existing larger components. Multifunctional active optical devices are emerging components that support miniaturization for diffraction-limited performance with simpler optical system designs in optical devices. In a recent study, Tianbo Liu and a team of researchers in the departments of Electrical and Computer Engineering and Dermatology in the U.S.

New imaging method aids in water decontamination

A breakthrough imaging technique shows promise in decontaminating water by yielding surprising and important information about catalyst particles that can't be obtained any other way.

Pairing 'glue' for electrons in iron-based high-temp superconductors studied

Newly published research sheds more light on the nature of high-temperature iron-based superconductivity.

Playfully discover atom manipulation

Scientists have used an electron microscope to manipulate strongly bound materials with atomic precision. Since the instruments used are fully computerized, it is possible to show in a simulation how researchers actually use them. A simulation game has now also been released online, together with the latest research advance of silicon impurity manipulation in single-walled carbon nanotubes.
