The move by Intel is a substantial increase in memory speeds from prior generations.

Engineers and developers at Intel are always working to push the boundaries of what’s possible, leaning on Moore’s Law — the idea that the number of transistors on a single chip will double every two years with a minimal increase in cost.

But over the last five years, Intel has had its ups and downs, demonstrated by the wavering value of its stock. It went from a high of $68 per share to more recently trading at $36 per share.

Indeed, the costs of building fabs in Germany, Japan, and the U.S. are higher than the costs of building fabs in Taiwan and TSMC has complained about it a number of times in the past. The company even had to delay production start at its Fab 21 near Phoenix, Arizona, due to problems with tools installation and negotiations with trade unions.

Therefore, if a TSMC customer wants to produce its chips at a specific location, then the foundry will charge a premium. How high is that premium will be remains to be seen, but last year a media report indicated that chips made in Arizona on TSMC’s N5 and N4 production nodes could be from 20% to 30% more expensive than the same chips produced in Taiwan.

Due to higher construction and operational expenses of fabs in Japan, Germany, and the U.S., TSMC plans to transfer these additional costs to its customers to sustain its target gross margin of 53%. Although American chip designers may not welcome the increased production costs in the U.S., they will probably manufacture chips intended for government and other markets less sensitive to price increases at the Arizona facility. Consequently, they should manage to pass on these higher costs to at least some of their end customers without jeopardizing their market competitiveness.

Researchers at the University of Würzburg have developed a method that can improve the performance of quantum resistance standards. It’s based on a quantum phenomenon called the Quantum Anomalous Hall effect.

The precise measurement of electrical resistance is essential in the industrial production of electronics – for example, in the manufacture of high-tech sensors, microchips, and flight controls. “Very precise measurements are essential here, as even the smallest deviations can significantly affect these complex systems,” explains Professor Charles Gould, a physicist at the Institute for Topological Insulators at the University of Würzburg (JMU).

With our new measurement method, we can significantly improve the accuracy.

An international collaboration of researchers, led by Philip Walther at University of Vienna, have achieved a significant breakthrough in quantum technology, with the successful demonstration of quantum interference among several single photons using a novel resource-efficient platform. The work published in Science Advances represents a notable advancement in optical quantum computing that paves the way for more scalable quantum technologies.

A collaboration of scientists from various universities in the UK and Europe have stored and retrieved data from quantum computers, marking a “crucial connection for ‘quantum internet,’” in a global first.

This is an essential step in quantum networking as the world gears up for the next generation of computing.

With its ultrafast computational speeds, quantum computing is touted to solve the world’s problems in designing new drugs, understanding the properties of materials, and optimizing financial risk.

An international research team led by scientists from the CNRS has discovered that the magnetic nanobubbles known as skyrmions can be moved by electrical currents, attaining record speeds up to 900 m/s.

Researchers have shown that double-layer graphene can function both as a superconductor and an insulator, a property that could revolutionize transistor technology. This dual functionality allows for the development of nanoscale transistors that are highly energy-efficient.

An international research team led by the University of Göttingen has demonstrated experimentally that electrons in naturally occurring double-layer graphene move like particles without any mass, in the same way that light travels. Furthermore, they have shown that the current can be “switched” on and off, which has potential for developing tiny, energy-efficient transistors – like the light switch in your house but at a nanoscale. The Massachusetts Institute of Technology (MIT), USA, and the National Institute for Materials Science (NIMS), Japan, were also involved in the research. The results were published in the scientific journal Nature Communications.

The expansion of fiber optics is progressing worldwide, which not only increases the bandwidth of conventional Internet connections, but also brings closer the realization of a global quantum Internet. The quantum internet can help to fully exploit the potential of certain technologies. These include much more powerful quantum computing through the linking of quantum processors and registers, more secure communication through quantum key distribution or more precise time measurements through the synchronization of atomic clocks.

However, the differences between the glass fiber standard of 1,550 nm and the system wavelengths of the various quantum bits (qubits) realized to date represent a hurdle, because those qubits are mostly in the visible or near-infrared spectral range. Researchers want to overcome this obstacle with the help of quantum frequency conversion, which can specifically change the frequencies of photons while retaining all other quantum properties. This enables conversion to the 1,550 nm telecom range for low-loss, long-range transmission of quantum states.
