Benchmarks for Application-Centric Quantum Computing (BACQ)
The Q-score is a metric designed to evaluate the performance of quantum processors and the entire quantum computing stack for solving real-world problems.
Turning qubit noise into an advantage: Automatic state preparation and long-time dynamics for impurity models on quantum computers
Noise is often regarded as a limitation of quantum computers. In this work, we show that in the dynamical mean field theory (DMFT) approach to strongly-correlated systems, it can actually be harnessed to our advantage.

"Qaptiva HPC marks a significant advancement in quantum emulation for high-performance computing. Quantum simulators, such as Qaptiva, offer quantum computing researchers, software developers, and end users an opportunity to fine tune their quantum computing efforts within a classical compute environment, mitigating the uncertainties and related errors that are inherent in current generation NISQ systems. Perhaps equally important, Qaptiva can be run on users' existing HPC hardware. Such capabilities could prove to be a valuable asset for those looking to harness the power of quantum computing for numerical simulation."
"Bull is a global leader in Quantum Computing and with the launch of Qaptiva™, a complete as-a-service offer focused on applications development, Bull is on the right path toward rapid innovation and adoption of Quantum Computing for enterprises and businesses."
"With its proven expertise in High Performance Computing (HPC), Eviden will speed up the adoption of hybridisation to combine quantum, traditional HPC and AI at scale. Bull has all the critical elements and potential to contribute meaningfully to the future of Quantum Computing."
