Chinese researchers are reporting they can break RSA encryption with a contemporary Quantum Computer. Can they? — This is a brief post in response to the current focus on the topic. Something longer will follow. Q: Will quantum computers defeat encryption? A: Yes, certain types on encryption, including many that are in common use today. Q: Do we see that as an immediate, existential threat? A: No…

A thank you to Brian and Em for linking to our substack — Quantum London has a substack account. You might not be aware as the material there is basically the same as here so no need to be in both places. Substack does get a difference audience though so delighted to thank both Brian Lenahan and Emanuele Colonnella for listing Quantum London…

An old by still relevant paper from BCG — A BCG paper linked to the Davos 2020 discussion talking about how quantum computing can help in the medium term when it comes to meaningfully reducing emissions At one level this is old, but in fact the points all stand valid and while more detailed work has been done in…

A summary of posts and photos from 11 October 2022 — On Tuesday 11 October the second City Quantum Summit took place at the splendid Mansion House in London, organised flawlessly by Karina Robinson. Below we’ve captured some of the summaries and thoughts are participants from their LinkedIn posts. Based on the success of the event it totally deserves to return…

Quantum Computing insight from UCL (University College, London) — As Quantum Computing continues to slowly enter the mainstream there is a need for explaining what it means for business users. This series from UCL’s Q-LABs and Quantum Science and Technology Institute aims to do that. Quantum ready podcast Is your business quantum ready? Explore how quantum computing can help your business. Episode 1: What is quantum computing?

Event on Monday 27 June — Delighted to share this webinar planned by SandboxAQ. Quantum Computers are expected to break modern public key cryptography leveraging Shor’s algorithm. As a result, these cryptosystems need to be replaced by quantum-resistant algorithms, also known as post-quantum cryptography (#PQC) algorithms to protect against Store Now, Decrypt Later attacks and other…
