Bulk Entanglement Gravity without a Boundary: Towards Finding Einstein's Equation in Hilbert Space
ChunJun Cao, Sean M. Carroll
We consider the emergence from quantum entanglement of spacetime geometry in a bulk region. For certain classes of quantum states in an appropriately factorized Hilbert space, a sp…
De Sitter Space as a Tensor Network: Cosmic No-Hair, Complementarity, and Complexity
Ning Bao, ChunJun Cao, Sean M. Carroll +1
We investigate the proposed connection between de Sitter spacetime and the MERA (Multiscale Entanglement Renormalization Ansatz) tensor network, and ask what can be learned via suc…
Quantum Circuit Cosmology: The Expansion of the Universe Since the First Qubit
Ning Bao, ChunJun Cao, Sean M. Carroll +1
We consider cosmological evolution from the perspective of quantum information. We present a quantum circuit model for the expansion of a comoving region of space, in which initial…
Axion detection via Topological Casimir Effect
ChunJun Cao, Ariel Zhitnitsky
We propose a new table-top experimental configuration for the direct detection of dark matter axions with mass in the range using non-perturbati…
