You mentioned that the new worldwide definition of a second is based on the excitation of cesium atoms between 2 quantum states. You can buy a unit from Hewlett-Packard that does just that! They used to cost ~~$25K, I have no idea what they go for now. Output is an LED time readout, or 1 or 10 MHz (I think), accurate to about 3 parts in 10,000,000,000.
