Quantum Computing Challenged By Security, Error Correction


The number and volume of warnings about a post-quantum cryptography (PQC) world are rising, as governments, banks, and other entities prepare for a rash of compromised data and untrustworthy digital signatures. Exactly when this will become a genuine threat is still somewhat fuzzy, because it depends on progress in developing robust qubits. A report by McKinsey & Co. estimates that by 20... » read more

The Great Quantum Computing Race


Quantum computing is heating up, as a growing number of entities race to benchmark, stabilize, and ultimately commercialize this technology. As of July 2021, a group from China appears to have taken the lead in terms of raw performance, but Google, IBM, Intel and other quantum computer developers aren’t far behind. All of that could change overnight, though. At this point, it's too early t... » read more

Reading About Quantum Computing


For the last several months, I’ve been working on a series of articles about quantum computing: how quantum computers are different from conventional computers, what materials systems might be appropriate for use in qubits, and, for the upcoming last article, how one might actually build and program a quantum computer. Some of the subtopics are familiar ground for me, and probably for most... » read more

Quantum Computer Race Heats Up


For years, there has been an intense race among various nations to develop the world’s fastest supercomputers. The U.S. and Japan led the field until 2010, when China stunned the market and rolled out the world’s fastest supercomputer. And today, China continues to lead the field with a supercomputer capable of running at speeds of 33.86 petaflops per second. While the supercomputer race... » read more
