Complexity of Digital Quantum Simulation in the Low-Energy Subspace: Applications and a Lower Bound
Digital quantum simulation has broad applications in approximating unitary evolution of Hamiltonians. In practice, many simulation tasks for quantum systems focus on quantum states in the low-energy subspace instead of the entire Hilbert space. In this paper, we systematically investigate the comple...
