The Current State of Quantum Technologies

I’ve been asked by a reader to write about the current state of quantum technologies. There has been a real buzz about it outside of the physics (academic) community for a while now and all the major companies are investing large amounts of money into it…

The Infamous Mod Square

Because everything in quantum physics behaves like a wave, the primary entities are given by what are known as amplitudes. Amplitudes can be thought of as propensities (to borrow a term from Aristotle) for a wave of one configuration to – later on – acquire another configuration.

What is life?

I know of at least three books with this title. The most famous one is, of course, by Erwin Schrödinger. If you haven’t read it, I really recommend it highly. It’s difficult to overstate its importance.

Spacetime and Memory

Despite the fact that the theory of relativity unified space and time into one entity called spacetime, many physicists (and philosophers and others) feel that time somehow holds a different status to space.

Do we really need a theory of everything?

Finding a theory of everything – explaining all the forces and particles in the universe – is arguably the holy grail of physics. But do we really need a theory of everything? That’s what I discussed in the final episode of the Great Mysteries of Physics podcast – hosted by Miriam Frankel, science editor at The Conversation, and supported by FQxI, the Foundational Questions Institute.

What is a “click”?

Every time we scientists submit a paper for publication, there is the so-called peer review. Our colleagues (‘peers’) are asked to read our submitted paper and evaluate it. This affects whether and how the paper needs to be revised and if, ultimately, it gets published.
