Welcome to season 2 finale of fAQ! For this season, Tai-Danae and Adam focused on a single topic: What is actually happening inside a quantum computer? By the end of this season, you'll have a better understanding of the "how" of quantum computing. So get ready to go beyond the theory and dig into what's actually going on these machines that harness the fundamental forces of the universe! In this sixth episode, we continue our exploration into DiVincenzo's fifth criterion for functional quantum computers: "Measurement of individual qubits". Specifically, we dig into what it means to "measure" something, in both the everyday context and in the quantum world. You might end up being surprised how similar those are and how not-strange measurement is in the quantum context...well at least some parts of those measurements! Oh, and we talk about how you, yes YOU, can work towards winning a Nobel Prize using the fAQ comment section ;-) Want to get in touch?

Heads-up, you might want to check out the video version of fAQ this time, there are a lot of graphics that will help you through this topic!Welcome to season 2 of fAQ!

For this season, Tai-Danae and Adam will be focusing on a single topic: What is actually happening inside a quantum computer? By the end of this season, you'll have a better understanding of the "how" of quantum computing. So get ready to go beyond the theory and dig into what's actually going on these machines that harness the fundamental forces of the universe!

In this fifth episode, we continue our exploration into DiVincenzo's fourth criterion for functional quantum computers: "A universal set of quantum gates". Specifically, we look at two-qubit gates and really dig into how quantum entanglement works and how to create it among trapped ions. And along the way, you'll hear about what old-school Nintendo cheat codes and not-stealing M&Ms has to do with all of this!

So get ready to go beyond the theory and dig into what's actually going on these machines that harness the fundamental forces of the universe!

In this second episode, we dig into DiVincenzo's first criterion for functional quantum computers: "A scalable physical system with well-characterized qubits". What does that mean? And do trapped ion quantum computers pass that test? And by the way, what's a trapped ion!? Learn about all of that and more...including a little something about Pringles!

In this first episode, we set the stage for the rest of the season by talking about why, if at all, you might want to care about quantum computing. Then we start to address the big elephant in the room whenever quantum computing comes up: hype! And finally, we describe the framework we'll be using for the rest of the season: DiVincenzo's criteria for a quantum computer.

In this episode, we’re continuing to talk about quantum applications.

You may have heard that quantum computer will break all passwords and security on the Internet...is that true?! How would that work?

Tai-Danae and Adam are joined again by physicist and SandboxAQ's VP of engineering, Stefan Leichenauer to discuss how most encryption works online right now, and how quantum computers will affect that.
