Imagine if there were quantum experiments already done by the universe — using cosmological time and energy scales to reveal signatures of quantum gravity & push fundamental physics to its limits? In the latest episode of the Quantum Foundations Podcast, @IyerAditya explains…
The many-worlds interpretation of quantum mechanics can seem to imply that branching is a global, irreversible process where parallel worlds are formed. In reality: - Branching happens locally - In principle it's reversible, and the parallel worlds can be re-merged
Pilot-wave theory vs Everettian:
It's not just the particle that has a pilot wave in that theory. Every pair of particles has one, in 6-dimensional space. And every triple, in 9-dimensional space etc. So the universe as a whole, in that theory, is called the 'particle' in a large space. And in the overall wave…
I’ve been looking forward to this. Julian has significantly advanced our understanding of time, and although we disagree on certain issues, particularly on quantum theory, he is always worth listening to.
Can time, quantum & cosmology be overturned with geometry? Nothing but ratios: that's the key message of physicist Julian Barbour's theory. In this recorded event, Barbour presents his ideas, and they are challenged by questions & comments from myself & the audience to create a…
Deriving the quantum multiverse from the cosmological principle:
The same physics applies everywhere: to the observed, unobserved and observers. That’s all you need to get to a multiverse from quantum theory.
We must necessarily quantize the scalar modes in the weak field limit to explain entanglement as proposed in the BMV experiment. The point of this experiment is to falsify semiclassical models where the gravitational field is purely classical (i.e. no non commuting observables).
It was great to speak at the Quantum Datacenter Alliance event in London last week! The day included industry-focused talks, panels & discussions, exploring how to solve technical challenges & scale up towards the quantum datacenters of the future. I chaired a panel about…
