The High Cost of Quantum Randomness Is Dropping
Randomness is essential to some research, but it’s always been prohibitively complicated. Now, we can use “pseudorandomness” instead. The post The High Cost of Quantum Randomness Is Dropping first appeared on Quanta Magazine
Nothing is certain in the quantum realm. A particle, for example, can exist in multiple quantum states simultaneously. The same goes for a quantum bit, or qubit — the basic unit of information used in quantum computing. The act of measurement causes these objects to collapse into a single state, and usually the best you can do is calculate the probability of a particular outcome.
