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?

She earned a PhD in mathematics from the CUNY Graduate Center and is creator of the mathematics blog, Math3ma, and a former cohost of PBS Infinite Series.

<p>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! </p>

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 fourth episode, we dig into DiVincenzo's fourth criterion for functional quantum computers: "A universal set of quantum gates". What is a "gate"? How is superposition an example? For that matter, what is superposition, functionally? And how can we get qubits into superposition inside a trapped-ion quantum computer? Come along for the exciting ride in this supersized episode!

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 third episode, we dig into DiVincenzo's second criterion for functional quantum computers: "The ability to initialize the state of the qubits to a simple fiducial state". What does that mean? And do trapped ion quantum computers pass that test? What about superconducting quantum computers? And what to ukuleles have to do with this?! Want to get in touch?

<p>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. </p>
