Quantum Reality — and Where Is It? Collapse, Schrödinger’s Cat, Parallel Universes

The great mystery of quantum mechanics is the nature of quantum reality.
It cannot be directly observed and reveals itself only through limited contact with our reality — yet this contact underlies the existence of key elements of the world.
One of the most important quantum properties is entanglement — a counterintuitive phenomenon that lies at the heart of quantum computing and quantum teleportation.
If entanglement truly extends to all scales, then it must also “pull apart” Schrödinger’s cat across multiple universes. This line of reasoning leads to the idea of branching universes coexisting in the same space.
In his lecture, Alexey Semikhatov will discuss the strengths and weaknesses of this grand concept and present recent results related to the structure of the “tree of universes.”
The lecture will be held in Russian.
After the talk, attendees will have the opportunity to ask questions, take photos, and have books signed.
Alexey Semikhatov — Doctor of Physical and Mathematical Sciences, Head of the Laboratory for the Theory of Fundamental Interactions at the Lebedev Physical Institute of the Russian Academy of Sciences, bestselling popular science author, and host of the TV program Question of Science and several science podcasts.
The lecture will take place in Dublin, on January 6 at 7:00 PM,
at the Davis Theatre, Arts Building, Trinity College Dublin.
