System Bits: Aug. 1


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

Entangling photons for bug-proof communication With the increasing processing power of computers, conventional encryption of data is becoming increasingly insecure, reminded Fraunhofer researchers that are proposing one solution is coding with entangled photons. The team is developing a quantum coding source that allows the transport of entangled photons from satellites, expected to be an impo... » read more

Diamonds for quantum computing Quantum computers are experimental devices that offer large speedups on some computational problems, and one promising approach to building them involves harnessing nanometer-scale atomic defects in diamond materials. At the same time, practical, diamond-based quantum computing devices will require the ability to position those defects at precise locations in com... » read more

AI systems echo human prejudices One of the concerns about the of future artificial intelligence systems includes the perception that these machine-based systems are coldly logical and objectively rational, however, this may not be the case. In fact, in a new study by Princeton University researchers has shown how machines can be reflections of their creators in potentially problematic ways. ... » read more

Power/Performance Bits: Feb. 21


Harvesting energy from multiple sources Researchers from the University of Oulu in Finland found a particular type of perovskite, KBNNO, has the right properties to extract energy from multiple sources simultaneously. While perovskites are particularly known for their use as solar cells, certain minerals in the perovskite family show piezoelectric and pyroelectric (harvesting energy from ... » read more

Rush Hour On The Technology Roadmap


Starting this week, the International Solid State Circuits Conference (ISSCC) will commence at the Marriott in downtown San Francisco. This prestigious conference showcases the latest semiconductor innovations from around the world. Looking at the advance program, one can’t help but notice a shift in the work presented. The conference theme this year is: “Intelligent Chips for a Smart World... » read more

Changing Direction In Chip Design


Andrzej Strojwas, chief technologist at PDF Solutions and professor of electrical and computer engineering at Carnegie Mellon University—and the winner of this year's Phil Kaufman Award for distinguished contributions to EDA—sat down with Semiconductor Engineering to talk about device scaling, why the semiconductor industry will begin to fragment around new architectures and packaging, and ... » read more

What’s Next For Transistors


The IC industry is moving in several different directions at once. The largest chipmakers continue to march down process nodes with chip scaling, while others are moving towards various advanced packaging schemes. On top of that, post-CMOS devices, neuromorphic chips and quantum computing are all in the works. Semiconductor Engineering sat down to discuss these technologies with Marie Semeri... » read more

Turning quantum systems from novelties into useful technologies In what is believed to be a major achievement that could help bring the strange and powerful world of quantum technology closer to reality, University of Sydney researchers have demonstrated the ability to “see” the future of quantum systems, and used that knowledge to preempt their demise. The applications of quantum-enabl... » read more
