Why are quantum computers fast? | Quantum Computing Weekly #3
By Jesper Thomschutz • Issue #3 • View online
đź‘‹ Hi everyone and welcome to the latest issue of Quantum Computing Weekly. Can you believe it has already been three weeks since the first issue?
In this issue we’ll be talking about what makes quantum computers fast, as well as covering the latest developments in QC for things like the automotive industry, storage, and quantum internet!
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
Why are quantum computers such a big deal? Yes, it’s true that they are faster than classical computers, but only in certain circumstances. In fact, don’t expect your future phone or laptop to be a quantum computer - but rather, that a quantum computer might be used as an add-on embedded chip for very specific tasks (like a graphics card (GPU) in a computer used for gaming and such). The magic of quantum computing lies in the qubits (read more in issue #1). While a classic digital computer has a bit that can represent either a 1 or a 0, a qubit can represent both at once. This leads to an exponential effect where a qubit is able to “calculate” all states in parallel, while the classic computer is churning along serially. It may in fact be a bit inaccurate to call this faster as it’s not a direct comparison - qubits are used to algorithms that aren’t feasible for classic computers to calculate, which yield fast answers for a narrow (but important!) domain of problems. To learn more check out this neat 2 minute video and then a more detailed explanation here. Still hungry for more info? This beauty will almost certainly keep you busy until next issue!

đź‘‹ 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.
