Quantum Kernels are Spectral Tensor Networks
Erik M. Ã sgrim, Stefano Markidis
Quantum kernels admit Fourier representations whose frequencies are determined by the data-encoding gates of the underlying feature map. We show that entangling tensor kernels are…

Tensor Network Compression for Fully Spectral Vlasov-Poisson Simulation
Erik M. Ã sgrim, Luca Pennati, Marco Pasquale +1
We propose a numerical method for kinetic plasma simulation in which the phase-space distribution function is represented by a low-rank tensor network with an adaptive level of com…

SWAP-Network Routing and Spectral Qubit Ordering for MPS Imaginary-Time Optimization
Erik M. Ã sgrim, Stefano Markidis
We propose a quantum-inspired combinatorial solver that performs imaginary-time evolution (ITE) on a matrix product state (MPS), incorporating non-local couplings through structure…
