Australia moves to drop some cryptography by 2030 – before quantum carves it up (theregister.com)
Australia's chief cyber security agency has decided local orgs should stop using the tech that forms the current cryptographic foundation of the internet by the year 2030 – years before other nations plan to do so – over fears that advances in quantum computing could render it insecure.

Google says its new quantum chip indicates that multiple universes exist (techcrunch.com)
Google on Monday announced Willow, its latest, greatest quantum computing chip. The speed and reliability performance claims Google’s made about this chip were newsworthy in themselves, but what really caught the tech industry’s attention was an even wilder claim tucked into the blog post about the chip.

The case against Google's claims of "quantum supremacy" (wordpress.com)
The 2019 paper “Quantum supremacy using a programmable superconducting processor”  asserted that Google’s Sycamore quantum computer,  with 53 qubits and a depth of 20, performed a specific computation in about 200 seconds. According to Google’s estimate, a state-of-the-art classical supercomputer would require approximately 10,000 years to complete the same computation.

Quantum error correction below the surface code threshold (nature.com)
Quantum error correction [1, 2, 3, 4] provides a path to reach practical quantum computing by combining multiple physical qubits into a logical qubit, where the logical error rate is suppressed exponentially as more qubits are added.

Understanding Google's Quantum Error Correction Breakthrough (quantum-machines.co)
Imagine trying to balance thousands of spinning tops at the same time—each top representing a qubit, the fundamental building block of a quantum computer. Now imagine these tops are so sensitive that even a slight breeze, a tiny vibration, or a quick peek to see if they’re still spinning could make them wobble or fall. That’s the challenge of quantum computing: Qubits are incredibly fragile, and even the process of controlling or measuring them introduces errors.

The Case Against Quantum Computing (2018) (ieee.org)
Quantum computing is all the rage. It seems like hardly a day goes by without some news outlet describing the extraordinary things this technology promises. Most commentators forget, or just gloss over, the fact that people have been working on quantum computing for decades—and without any practical results to show for it.
