The ultimate non-technical guide to the fast-developing world of quantum computing.

Computer technology has improved exponentially over the last 50 years. But the headroom for bigger and better electronic solutions is running out. Our best hope is to engage the power of quantum physics. ‘Quantum algorithms’ had already been written long before hardware was built. These would enable, for example, a quantum computer to exponentially speed up an information search, or to crack the mathematical trick behind internet security. However, making a quantum computer is incredibly difficult. Despite hundreds of laboratories around the world working on them, we are only just seeing them come close to ‘supremacy’ where they can outperform a traditional computer.

In this approachable introduction, Brian Clegg explains algorithms and their quantum counterparts, explores the physical building blocks and quantum weirdness necessary to make a quantum computer, and uncovers the capabilities of the current generation of machines.©2021 Icon Books Ltd (P)2022 W.

I liked the excellent and detailed explanation. The narration flowed excellently for me. I would recommend this

Spends far too long describing things which are not the subject of the book. The chapter on Quantum algorithms for example, explains everything but how a Quantum algorithm works. It lists a few famous ones, sure, but no attempt to dig into how any of them work, instead the chapter is packed full of random digressions into all sorts of other conventional algorithms and mildly interesting other topics.

Factual errors in other parts of the book also, for example, Sat Nav is not a full reduction of TSP, it’s a simpler, more constrained problem. Logic gates don’t need only two inputs for the non-unary ones, etc.

Having put the graft in through the first few chapters, very sad with the incredibly limited pay off. I didn’t even really walk away with even the basic grasp of any quantum techniques. If you’re looking for anything beyond the most surface skim of understanding, look elsewhere.

Very shallow
