We present a polynomial-time quantum algorithm for obtaining the energy spectrum of a physical system. A probe qubit is coupled to a quantum register that represents the system of interest such that the probe qubit exhibits a dynamical response only when it is resonant with a transition in the system. By varying the probe's frequency and the system-probe coupling operator, any desired part of the energy spectrum can be obtained. The algorithm can also be used to deterministically prepare any energy eigenstate. As an example, we have simulated running the algorithm and obtaining the energy spectrum of the water molecule.
