Quantum Computation with Machine-Learning-Controlled Quantum Stuff
Lucien Hardy, Adam G. M. Lewis
We describe how one may go about performing quantum computation with arbitrary "quantum stuff", as long as it has some basic physical properties. Imagine a long strip of stuff, equ…
Classical Simulations of Quantum Field Theory in Curved Spacetime I: Fermionic Hawking-Hartle Vacua from a Staggered Lattice Scheme
Adam G. M. Lewis, Guifré Vidal
We numerically compute renormalized expectation values of quadratic operators in a quantum field theory (QFT) of free Dirac fermions in curved two-dimensional (Lorentzian) spacetim…
Hadamard Renormalization of a 2-Dimensional Dirac Field
Adam G. M. Lewis
The Hadamard renormalization procedure is applied to a free, massive Dirac field on a 2 dimensional Lorentzian spacetime. This yields the state-independent divergent terms in t…
Automatic generation of CUDA code performing tensor manipulations using C++ expression templates
Adam G. M. Lewis, Harald P. Pfeiffer
We present a C++ library, TLoops, which uses a hierarchy of expression templates to represent operations upon tensorial quantities in single lines of C++ code that resemble analyti…
GPU-Accelerated Simulations of Isolated Black Holes
Adam G. M. Lewis, Harald P. Pfeiffer
We present a port of the numerical relativity code SpEC which is capable of running on NVIDIA GPUs. Since this code must be maintained in parallel with SpEC itself, a primary desig…
