A new quantum algorithm has been implemented for quantum chemical calculations such as Full-CI on quantum computers without exponential/combinatorial explosion, giving exact solutions of Schroedinger Equations for atoms and molecules, for the first time.
Challenge any modern human to go a day without a phone or computer, and you'd be hard pressed to get any takers. Our collective obsession with all things electronic is driving a dramatic daily drain on the world's power. In fact, according to studies from the Semiconductor Research Corporation, if we continue on pace with our current ever-increasing energy consumption, by the year 2035, we will use all of the world's energy to run our computers - an impossible/unsustainable situation.
Quantum biology, a young and increasingly popular science genre, isn't as new as many believe, with a complicated and somewhat dark history, explain the founders of the world's first quantum biology doctoral training center.
A team of researchers has developed an algorithm for predicting the effect of an external electromagnetic field on the state of complex molecules. The new algorithm, presented in a paper in The Journal of Chemical Physics, enables researchers to look inside large polyatomic molecules, observe and potentially control electron motion therein.
Researchers have created tiny droplets of the ultra-hot matter that once filled the early universe, forming three distinct shapes and sizes: circles, ellipses and triangles.
Research teams from UNSW are investigating multiple pathways to scale up atom-based computing architectures using spin-orbit coupling -- advancing towards their goal of building a silicon-based quantum computer in Australia.
Harnessing nuclear fusion, which powers the sun and stars, to help meet earth's energy needs, is a step closer after researchers showed that using two types of imaging can help them assess the safety and reliability of parts used in a fusion energy device.
NIST scientists have now developed a highly efficient device that enlarges the diameter of a light beam by 400 times. Wider light beams have many applications, including boosting the speed and sensitivity of medical imaging and diagnostic procedures.
Experimental atomic clocks at the National Institute of Standards and Technology (NIST) have achieved three new performance records, now ticking precisely enough to not only improve timekeeping and navigation, but also detect faint signals from gravity, the early universe and perhaps even dark matter.
Physicists from ITMO University developed a model of an optical tractor beam to capture particles based on new artificial materials. Such a beam is capable of moving particles or cells towards the radiation source. The study showed that hyperbolic metasurfaces are promising for experiments on creating the tractor beam, as well as for its practical applications. The results are published in ACS Photonics.
