Quantum Circuit Simulators (QCS) play a key role in the development of algorithms, potential applications, and research into more capable quantum processors. It is therefore important for QCS to offer the ability to execute larger quantum volumes in a reasonable amount of time on classical computers. Today, the most commonly used simulation methods are state vector and tensor network methods, which are both computationally intensive and benefit greatly from GPU acceleration. This is why we are introducing the NVIDIA cuQuantum SDK that will provide APIs to accelerate QCS that rely on both methods. In this talk, we will look at the early capabilities of cuQuantum libraries and demonstrate the performance impact on some benchmark simulations.
