How to make a qubit | Quantum Computing Weekly #2

By Jesper Thomschutz • Issue #2 • View online

👋 Hi everyone and welcome to the second issue of Quantum Computing Weekly.

In this issue we’ll be covering a quick run through of the history of quantum computing, talk about how qubits are implemented in real life as well as recent news and development in the industry. There’s especially interesting news regarding how QC can be commercialized and fast-tracked to a wider audience.

Tiny Fact of the week

In the previous issue we introduced the concept of qubit - but how do you actually create a qubit in reality? There are a handful of ways currently being used today. One popular method is to use the spin of an electron (down/low-energy or up/high-energy), but there are other methods as well, such as the polarization of a single photon (as an example: 1 for vertical or 0 for horizontal).

The WIRED Guide to Quantum Computing

In this article WIRED presents a brief run through of the history of quantum computing as well as touching a bit on what the future holds. Worth a look especially if you’re very new to the world of QC.

Quantum computing ‘breakthrough’ could lead to commercialization

Sussex University scientists believe they have made a “breakthrough” in quantum computing that could pave the way to commercialization of the technology by making it useful outside of strict laboratory conditions.

Integrated quantum chip operations possible, tests show

For the first time, an Australian team has combined two fundamental quantum techniques on an integrated silicon platform, confirming the promise of silicon – the basis of all modern computer chips – for quantum computing.

Berkeley computer theorists show path to verifying that quantum beats classical

Researchers have just found a way to show that quantum computing beats classical computing by giving a leading practical proposal known as random circuit sampling (RCS) a qualified seal of approval with the weight of complexity theoretic evidence behind it. They showed that producing a random output with a ‘quantum accent’ is indeed hard for a classical computer through a technical complexity theoretic construct called ‘worst-to-average-case reduction.’

👋 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.
