Google’s quantum computing plans threatened by IBM curveball
https://www.newscientist.com/article/215...curveball/
EXCERPT: Just when it was looking like the underdog, classical computing is striking back. IBM has come up with a way to simulate quantum computers that have 56 quantum bits, or qubits, on a non-quantum supercomputer – a task previously thought to be impossible. The feat moves the goalposts in the fight for quantum supremacy, the effort to outstrip classical computers using quantum ones.
It used to be widely accepted that a classical computer cannot simulate more than 49 qubits because of memory limitations. The memory required for simulations increases exponentially with each additional qubit...

Why do computers and smart phones slow down over time?

EXCERPT: There are plenty of conspiracy theories seeking to explain why our phones, tablets and computers always slow down as they get older.
Internet searches for "iPhone slow" spike after the release of a new-generation model, but there's no evidence to suggest that manufacturers deliberately degrade the performance of older devices with software updates.
Computer hardware does not typically slow down over its useful life. Instead, there are several other reasons why smartphones, tablets and PCs start to seem less snappy. The good news is that you can often take steps to improve your existing device's performance....
