People have accomplished this, you just have to reduce the temperature to absolute zero. Then, you can basically manipulate particles at a quantum level by bombarding frozen hydrogen (at 0 degrees kelvin) with protons, making it helium. This is a very strange affect, and is being experimented on (I am sure of it) by the military. They have uncensored telescopes that they admit to being 1 degrees kelvin, so if they can accomplish that they can accomplish zero kelvin.
