Hamiltonian Simulation Using Linear Combinations of Unitary Operations

27 Feb 2012Andrew M. ChildsNathan Wiebe

We present a new approach to simulating Hamiltonian dynamics based on implementing linear combinations of unitary operations rather than products of unitary operations. The resulting algorithm has superior performance to existing simulation algorithms based on product formulas and, most notably, scales better with the simulation error than any known Hamiltonian simulation technique...
