👋 Howdy folks and thanks for taking a look at this fourth issue of QCM.
This weekend was a bit hectic for me as I took part in a 24h hackathon, which although was a lot of fun, was very draining - and in fact I still feel like I’m recovering from it!
In this issue we’ll find out where you can find the fastest ne best quantum computer in the world, as well as catch up with some headlines - including one particularly interesting article about the application of neural nets for improving quantum computing.
Got any particular area of quantum computing you’d like to see covered in the next issue? Ping me and let me know!

Tiny Fact of the week
Although it’s difficult to compare quantum computing implementations in real life, the one metric which is easiest to compare is the number of qubits. One of the kings of qubits is actually rather old, from 2016 - the D-Wave 2000Q 2,000 Qubit computer. This blows the 50 qubit computers from the likes of IBM, Intel, and Google out of the water - but is it actually any betters? It seems that some experts don’t think so, apparently the benchmarks are conflicting, and it’s a bit up in the air. I imagine the truth is somewhere in the middle, and the fact that measuring the power of quantum computing is still not well understood.
Like I said in thee beginning, comparing quantum computers is difficult, because there are many different factors that come in to play - for example, the duration of which a quantum state can be held. For example, the 50q IBM system can only hold its state for 90 microseconds.
Learn
Want to play with a real life quantum computer but don’t know where to start? Try using one remotely online, via a cloud provider. IBM and AWS have been offering their own for some time, and now D-Wave has joined in as well with Leap last month. Gain access to the controversial (see above) 2000 qubit computer and play with the open source SDK for first hand quantum computing experience! Read more here and access the service itself here.

👋 Hi folks and welcome to Quantum Computing Weekly!

This is a newsletter about Qubits, Quantum Logic Gates, occasional mandatory cat jokes, and more.

First off, let me get this out of the way: I'm not a quantum computing expert - not a Ph.D. in anything - just a humble legacy-computer programmer with a passion to learn more about the world of quantum computing.

Join me on my journey with this newsletter as I share news, articles, videos, and anything else I come across that I think is interesting while learning about quantum computers.
