Siva Darbha, Alexey Khudorozhkov, Pedro L. S. Lopes +11
The dynamics of isolated quantum systems following a sudden quench plays a central role in many areas of material science, high-energy physics, and quantum chemistry. Featuring com…
Quantum Computing Technology Roadmaps and Capability Assessment for Scientific Computing -- An analysis of use cases from the NERSC workload
Daan Camps, Ermal Rrapaj, Katherine Klymko +6
The National Energy Research Scientific Computing Center (NERSC), as the high-performance computing (HPC) facility for the Department of Energy's Office of Science, recognizes the…
Vectorized Attention with Learnable Encoding for Quantum Transformer
Ziqing Guo, Ziwen Pan, Alex Khan +1
Vectorized quantum block encoding provides a way to embed classical data into Hilbert space, offering a pathway for quantum models, such as Quantum Transformers (QT), that replace…
