We already have that technology, more or less... A orion type drive is can be built using 1960's technology, the rest is just engineering, not new physics. A orion type drive can take you as close to c as you can afford. At 0.9999999c you can travel to A.Centauri in 1/2 day. Granted getting to 0.9999999 and back again is gonna take a fair pile of h-bombs.
