SUMMARY:RosneT: A Block Tensor Algebra Library for Out-of-Core Quantum Com
 puting Simulation
DESCRIPTION:Workshop\n\nRosneT: A Block Tensor Algebra Library for Out-of-
 Core Quantum Computing Simulation\n\nSanchez-Ramirez, Garcia-Saez, Conejer
 o, Lordan, Queralt...\n\nWith the advent of more powerful Quantum Computer
 s, the need for larger Quantum Simulations has boosted. As the amount of r
 esources grows exponentially with size of the target system Tensor Network
 s emerge as an optimal framework with which we represent Quantum States in
  tensor factorizations. As the extent of a tensor network increases, so do
 es the size of intermediate tensors requiring HPC tools for their manipula
 tion. Simulations of medium-sized circuits cannot fit on local memory, and
  solutions for distributed contraction of tensors are scarce. In this work
  we present RosneT, a library for distributed, out-of-core block tensor al
 gebra. We use the PyCOMPSs programming model to transform tensor operation
 s into a collection of tasks handled by the COMPSs runtime, targeting exec
 utions in existing and upcoming Exascale supercomputers. We report results
  validating our approach showing good scalability in simulations of Quantu
 m circuits of up to 53 qubits.\n\nTag: Online Only, Algorithms, Quantum Co
