SUMMARY:Enabling Quantum Computer Simulations on AMD GPUs:  A HIP Backend 
 for Google's qsim
DESCRIPTION:Workshop\n\nStefano Markidis (KTH Royal Institute of Technolog
 y, Sweden)\n\nQuantum computer simulators play an essential role in advanc
 ing the field of quantum computing, serving as indispensable tools for qua
 ntum computer verification, debugging, and quantum algorithm prototyping. 
 Among these simulators, Google's state vector quantum simulator qsim has g
 ained significant popularity for its high performance and support for AVX5
 12 vector instructions, OpenMP, and NVIDIA GPUs. However, the lack of supp
 ort for AMD GPUs presents a limitation in qsim's widespread applicability 
 to current large-scale supercomputers with AMD GPUs, including the current
  fastest supercomputer in the world, Frontier. This work addresses this ga
 p by developing a qsim software backend that leverages the AMD HIP (Hetero
 geneous-Compute Interface for Portability) programming interface and tools
 . We discuss the efficiency and effectiveness of the newly introduced supp
 ort for AMD GPUs through performance evaluations and comparisons with the 
 existing Nvidia GPU backend.\n\nTag: Quantum Computing, Software Engineeri
