Quantum stealth communications and causality

Entanglement, Stern-Gerlach and the double slit experiment enable instantaneous, undetectable, yet causality preserving communications. The proposal has potential practical applications for secure and for space exploration communications, yet its most intriguing implications are in physics: Analysis of the proposal leads to a minimalist view of causality: only the irreducible consequences (i.e., with no additional implicit assumptions) of the speed of light in vacuum being a constant which is the same for all inertial observers. It also helps explain how information might leak out of black holes; how, in principle, experiments might distinguish between some proposals for black hole dynamics, in particular fire wall vs fire ball; and re-examination of the cosmological horizon.

You will receive zoom access info via meetup message and/or email (if I have your email address) shortly after you RSVP, provided it is before noon on 8/2/20.
