It’s All (Quantum) Smoke and Mirrors

An excited atom in an optical cavity becomes a sharp test of quantum timing. Three predictions on when a detector should click, one experimental answer. The result points to entanglement, not anything spooky, as the real driver.

No space, no time, no particles

Quantum reality may not depend on particles, space or time, but on quantum numbers themselves – a shift that reveals a deeper, more elegant view of the universe.

A Thermometer for Measuring Quantumness

At the quantum scale, heat can flow from cold to hot – a phenomenon that offers physicists a simple, non-destructive way to detect entanglement and other quantum effects. This “anomalous” heat flow could help verify quantum computers and even test whether gravity is quantum.

Why I wrote “Portals to a New Reality”

My new book is about the next revolution in physics. It explains in an accessible manner what I believe to be five key ‘thought experiments’ that will provide us with clues about what our next fundamental laws should be like. Each central chapter is about one such experiment – its motivations and how it will allow us to open a window on the future theory of physics.

Quantum physics is relative too

It’s very popular these days to emphasise differences between quantum physics and the theory of relativity. Some people even maintain that some of these are irreconcilable, which is why – or so proponents of this view maintain – we will not be able to quantize gravity (gravity being captured by the general theory of relativity).

Constrained or Unconstrained Quantum?

I’ve noticed something interesting a while ago, but I haven’t had a chance to blog about it yet. And I probably still wouldn’t have, but I was awakened from my incredibly comfortable lazy state (at least as far as blogging is concerned) by a recent Nature editorial on the interpretations of quantum physics.
