Quick Recap
Time Cristals, the topic of the week. If it wasn’t for the biggest funding round in Quantum so far. $450M for PsiQuantum with a valuation of $3,1B. Beautiful documentary by TQD folks on the future of Quantum.
And a new exciting community is born, Quantum Entangle Community. Join us there for great conversations

Paper: Quantum walk-based portfolio optimisation
This paper proposes a highly efficient quantum algorithm for portfolio optimisation targeted at near-term noisy intermediate-scale quantum computers. Recent work by Hodson et al. (2019) explored potential application of hybrid quantum-classical algorithms to the problem of financial portfolio rebalancing. In particular, they deal with the portfolio optimisation problem using the Quantum Approximate Optimisation Algorithm and the Quantum Alternating Operator Ansatz. In this paper, we demonstrate substantially better performance using a newly developed Quantum Walk Optimisation Algorithm in finding high-quality solutions to the portfolio optimisation problem.

Video: Quantum Information’s Revolutionary Origins | Charles Bennett
Quantum information? Charles Bennett discusses the physicality of information, and the revolutionary ideas and thinkers that led up to the fusion of physics and computer science that eventually gave birth to the field of quantum information.
Video: Quantum Technology | Our Sustainable Future
This new documentary feature from The Quantum Daily explores insights from leading quantum computing experts and tech giants such as Google, IBM, Oxford Instruments and Intel as well as start-ups such as PsiQuantum to discuss key sustainability topics, including how quantum technologies could reduce
Preparing for the Post-Quantum Migration: A Race to Save the Internet
This article was authored by Robert Botkin with help from Nicholas Acevedo. Most people don’t know, or care to know, about cryptography. Without cryptography, the internet privacy that we all rely on for transmitting virtually all forms of digital communication would be insecure from attackers.
