Blockchain integrated into energy systems Researchers at Canada’s University of Waterloo integrated blockchain technology into energy systems, a development that may expand charging infrastructure for electric vehicles. In a study that outlines the new blockchain-oriented charging system, the researchers found that there is a lack of trust among charging service providers, property owners... » read more

Faster U.S. supercomputers on the way The U.S. Department of Energy awarded a contract for more than $600 million to Cray for an exascale supercomputer to be installed at the Oak Ridge National Laboratory during 2021. Cray will provide its Shasta architecture and Slingshot interconnect for what is dubbed the Frontier supercomputer. Advanced Micro Devices will have a key role in building the... » read more

Reading qubits faster Researchers at Aalto University and VTT Technical Research Centre of Finland propose a faster way to read information from qubits, the building blocks of quantum computers. Currently, they are extremely sensitive to disruption even in cryogenic environments, holding quantum information for less than a millisecond. In the method now used to read information from a qubit... » read more

Quantum Issues And Progress
By Katherine Derbyshire - 07 Jan, 2019 - Comments: 3

Quantum computing is showing significant promise, and research is beginning to move from the earliest stages to a deeper understanding of what works best commercially and why. On paper, quantum computing algorithms are potentially revolutionary. They suggest a way to solve some problems more quickly and more accurately than conventional computers ever could. But out in the real world of prac... » read more

Schottky diodes: One 2D material equation to rule them all Specifying the right materials for the heterostructure of 2D Schottky diodes—which consist of a metal touching a semiconductor—means designers have to wade through sometimes conflicting theoretical models to select materials. “It is not uncommon to see a model, whose underlying physics fundamentally contradicts with the physical ... » read more

Quantum Computing Becoming Real
By Ed Sperling - 21 Jun, 2018 - Comments: 4

Quantum computing will begin rolling out in increasingly useful ways over the next few years, setting the stage for what ultimately could lead to a shakeup in high-performance computing and eventually in the cloud. Quantum computing has long been viewed as some futuristic research project with possible commercial applications. It typically needs to run at temperatures close to absolute zero,... » read more

Investigating the human brain for quantum computation potential While much has been made of quantum computing processes using ultracold atoms and ions, superconducting junctions and defects in diamonds, researchers are questioning if this could be performed in human brains. In fact, UC Santa Barbara theoretical physicist Matthew Fisher has been asking this question for years. And now as scient... » read more

Toward Defining Qubits
By Ed Sperling - 06 Sep, 2017 - Comments: 0

Quantum computing, by many accounts the future of high-performance computing, will be blazing fast, state-dependent, and it will require extremely cold operating temperatures. But beyond some general areas of agreement, comparing progress made by companies or different research groups is confusing. What's missing is a simple nomenclature to define some of the basic technology used in quantum... » read more

Quantum Computing Takes A Step Forward UCLA physicists have developed a technique for measuring and controlling the energy differences of electron valley states in silicon quantum dots, which they view as a key component of quantum computing. Joshua Schoenfield, a UCLA graduate student and one of the paper's authors, explained that "an individual qubit can exist in a complex wave-like m... » read more
