  Qubit reset is crucial at the start of and during quantum information
algorithms. We present the experimental demonstration of a practical method to
force qubits into their ground state, based on driving certain qubit and cavity
transitions. Our protocol, called the double drive reset of population is
tested on a superconducting transmon qubit in a three-dimensional cavity. Using
a new method for measuring population, we show that we can prepare the ground
state with a fidelity of at least 99.5 % in less than 3 microseconds; faster
times and higher fidelity are predicted upon parameter optimization.
