Berkeley Laboratory and the RIKEN Interdisciplinary Theoretical and Mathematical Sciences (iTHEMS) program are co-hosting a workshop on Quantum Information Science

 

This international workshop will bring together researchers worldwide to discuss and collaborate on the latest developments in quantum technologies and quantum computing. Other focus areas will be algorithms, hybrid classical - quantum computing, error mitigation, and applications in physics and chemistry.  With an emphasis to galvanize the participants into future collaborations, in addition to presentations on recent trends, the workshop will dedicate time in the afternoons for facilitated brainstorming and planning sessions.
