Recent years have witnessed enormous pro gress toward harnessing the power of quantum mechanics and integrating it into novel technologies capable of performing tasks far beyond present-day capabilities. Future technologies such as quantum computing\, sensing and communication demand the ability to control microscopic quantum systems w ith unprecedented accuracy. This task is particularly daunting due to unwa nted and unavoidable interactions with noisy environments that destroy qua ntum information in a process known as decoherence. I will present recent progress in understanding and modeling the effects of multiple noise sourc es on the evolution of a quantum bit and show how this can be used to deve lop new ways to slow down decoherence. I will then describe a new general theory for dynamically combatting decoherence by driving quantum bits in s uch a way that noise effects destructively interfere and cancel out\, enab ling the high level of control needed to realize quantum information techn ologies.
