Determining the relative abundance of two different molecular species or the absolute number of molecules in a single sample is challenging. We describe an absolute counting method that can use ...

Researchers have developed a method for generating numbers guaranteed to be random, through the use of quantum mechanics. The experimental technique surpasses all previous methods for ensuring the ...

Researchers have devised a new kind of random number generator, for encrypted communications and other uses, that is cryptographically secure, inherently private and - most importantly - certified ...
