SUMMARY:Enabling Quantum Computer Simulations on AMD GPUs:  A HIP Backend 
 for Google's qsim
DESCRIPTION:Stefano Markidis (KTH Royal Institute of Technology, Sweden)\n
 \nQuantum computer simulators play an essential role in advancing the fiel
 d of quantum computing, serving as indispensable tools for quantum compute
 r verification, debugging, and quantum algorithm prototyping. Among these 
 simulators, Google's state vector quantum simulator qsim has gained signif
 icant popularity for its high performance and support for AVX512 vector in
 structions, OpenMP, and NVIDIA GPUs. However, the lack of support for AMD 
 GPUs presents a limitation in qsim's widespread applicability to current l
 arge-scale supercomputers with AMD GPUs, including the current fastest sup
 ercomputer in the world, Frontier. This work addresses this gap by develop
 ing a qsim software backend that leverages the AMD HIP (Heterogeneous-Comp
 ute Interface for Portability) programming interface and tools. We discuss
  the efficiency and effectiveness of the newly introduced support for AMD 
 GPUs through performance evaluations and comparisons with the existing Nvi
 dia GPU backend.\n\nTag: Quantum Computing, Software Engineering\n\nRegist
