We do love our cellphones. And we hate them, too, of course—when they drop a call, go dead in the middle of a conversation, or simply fail to work in another country. Soon we’ll probably be complaining about other things—perhaps that our handsets can’t receive satellite TV broadcasts or last more than a week on a single charge.

You might guess that better microelectronics will soon provide higher data rates, lower power consumption, and greater flexibility in the types of communication that our handsets can manage. To some extent, that’s true. But transistor advances alone will probably not be enough. The Moore’s Law world of regularly doubling transistor densities has brought us cheap PCs that outperform the multimillion-dollar mainframes of 30 years ago, but those incredible shrinking transistors might not do much to eliminate dropped calls. In this respect, the most significant improvements may, in fact, come from what seems a bizarre source: better mechanical components.

Dialing Down a Quantum Compute Glitch by 100,000x

A low-key solution to qubits’ cosmic ray problem

The kind of quantum computers that IBM, Google and Amazon are building suffer catastrophic errors roughly once every 10 seconds due to cosmic rays from outer space. Now a new study reveals a way to reduce this error rate by nearly a half-million-fold to less than once per month.

Quantum computers theoretically can find answers to problems no regular computer might ever hope to solve. Their key ingredients, known as quantum bits, or qubits, are linked together by a quantum effect known as entanglement.

This article is part of our exclusive IEEE Journal Watch series in partnership with IEEE Xplore.

Deep learning is a critical computing approach that is pushing the boundaries of technology – crunching immense amounts of data and uncovering subtle patterns that humans could never discern on their own. But for optimal performance, deep learning algorithms need to be supported with the right software compiler and hardware combinations. In particular, reconfigurable processors, which allow for flexible use of hardware resources for computing as needed, are key.
