Teleportation! In space!
Physicist: This isn’t a question anybody asked, just an interesting goings-on. A few weeks ago QUESS (QUantum Experiments at Space Scale) began teleporting quantum information to and from the Micius...

Q: With entangled particles, can you tell when/how the other particle is...
Physicist: Nope! You definitely can’t. Almost without exception, when you hear about quantum entanglement it’s described as some kind of communication or connection. Generally along the lines of...

Q: What is quantum immortality?
Physicist: A common refrain in quantum theory is “anything that can happen does”. Shockingly, and with total disregard for our own human experience, this seems to be true. When you consider what this...

Q: What is the “monogamy of entanglement”?
Physicist: The Monogamy of Entanglement is the statement that “maximally entangled” particles only show up in pairs. Entanglement is a sliding scale, so things can be non-entangled or a little...

Q: Can free will exist in our deterministic universe?
Physicist: It depends on what you mean by “free will” and where you draw the line on “determinism”. Both of these are a matter of opinion, so philosophers (and the rest of us) will have plenty to...

Q: Can you beat the uncertainty principle using entanglement, by measuring...
Physicist: The Uncertainty Principle is a little subtle. Most folk are introduced to it as “the more precisely you measure the position of a particle, the less precisely you can measure its momentum,...

Q: What is quantum supremacy? Is it awesome or worrisome?
Physicist: Mostly awesome. Eventually. Recently, some of the folk at Google claimed to have achieved “quantum supremacy” (here’s what they had to say about it). Google has, like many other big...

Q: Why are the laws of quantum mechanics so strange? Does it mean that we’re...
Physicist: We’re definitely missing something, but we’re always missing something. One of the most famous quotes about quantum physics, often used in lieu of a shrug, is due to St. Feynman: “If you...

A Quantum Computation Course
Physicist: I’ve been a little busy to post much here for a while, but you may be interested in what I’m working on, so here it is. I’m teaching an introductory course on quantum information and...

Q: What if the particles in the double slit experiment were conscious? Could...
The original question was: I find the double slit experiment super interesting and have lots of questions about it. But here’s one. What if the particles you send through the slits are conscious? You...

Q: If the universe gets split in the Many Worlds Interpretation, then why...
The original question from “A” was: I’m reading Sean Carroll’s book Something Deeply Hidden, which is entirely about Many Worlds, and I’m following along for the most part, but there’s something I...
