Digital quantum simulation is a promising application for computers. Their free programmability provides the potential to simulate unitary evolution of any many-body Hamiltonian with bounded spectrum by discretizing time operator through sequence elementary gates, typically achieved using Trotterization. A fundamental challenge in this context originates from experimental imperfections involved...

Two major approaches for the digital design simulation can be classified into event-driven and levelized-code method. The drawback of event-driven simulation is low efficiency while the levelized-code simulation has problems in supporting asynchronous design. Since most digital designs are synchronous digital we implemented a levelizedcode simulator targeting synchronous digital design. Leveliz...
