Tiny Fact of the week
This week we’ll learn a bit about something called quantum tunneling, which may have some massive implications for things like nuclear fusion and more.
The quantum tunneling effect is a quantum phenomenon which occurs when particles move through a barrier that, according to the theories of classical physics, should be impossible to move through. The barrier may be a physically impassable medium, such as an insulator or a vacuum, or a region of high potential energy.
In classical mechanics, when a particle has insufficient energy, it would not be able to overcome a potential barrier. In the quantum world, however, particles can often behave like waves. On encountering a barrier, a quantum wave will not end abruptly; rather, its amplitude will decrease exponentially. This drop in amplitude corresponds to a drop in the probability of finding a particle further into the barrier. If the barrier is thin enough, then the amplitude may be non-zero on the other side. This would imply that there is a finite probability that some of the particles will tunnel through the barrier.
As always, Wikipedia has an amazing article on this topic with a lot more details and is well worth a look.
What kind of jobs are out there for people in quantum computing? In this article Jay Gambetta lays out about 12 different types of roles, as well as some info on how to get in touch with IBM if you’re interested in a career in the field of quantum computing. Very cool!

Why Did NASA, Lockheed Martin, and Others Spend Millions on This Quantum Computer? — gizmodo.com
Quantum computers are probably the most misunderstood of nascent technologies, which makes sense, because their very basics rely on the hardest-to-grasp concepts of physics. That’s led to people making some ridiculous claims, like that they give you “god-like powers” and that they’re an “imminent threat.”
