A new type of quantum simulator can finally calculate the inside of a black hole, a task that has been impossible for every computer until now.
Traditional computers and even standard qubit-based quantum computers fail when trying to simulate the complex physics of gravity. This researcher developed a qumode-based system that uses continuous variables rather than simple on-off bits to handle these massive calculations. This setup can model the way high-spin particles and black hole dynamics behave at the quantum level. It provides a way to test theories of quantum gravity that were previously stuck in the realm of abstract pencil-and-paper math. This could be the breakthrough tool that finally helps us understand how space and time are stitched together at the most fundamental level.
Continuous-Variable Quantum Computing for Non-Compact Gauge Theories: Generalizing to Sp(2n, R) Lattices and Multi-Radial Holographic RG Flow

We extend continuous-variable quantum computing (CVQC) to non-compact lattice gauge theories by generalizing the SL(2, R) model to the full symplectic group Sp(2n, R) on the Siegel upper half-space (with explicit high-precision simulations performed for the representative case n = 2). Using the Iwasawa decomposition Sp(2n, R) = KAN with maximal compact subgroup K U(n) and multi-radial non-compact directions ρ = (ρ 1 ,. .. , ρ n) parametrized by the abelian subgroup A, we formulate Kogut-Susskind
