One worry about any random-number generator is that the numbers could be influenced in a predictable way by non-quantum (classical) effects in the system. This could lead to a measurement bias, for ...

A perfectly provable random number generator is the bedrock of good cryptography. This scientist wants to make one.

For example, traditional computers may create encryption based on the result of multiplying two large prime numbers together, generating a seemingly random number.

A new laser’s chaotic light beam lets the device generate multiple number sequences at once, similar to throwing multiple dice at a time.

Using a single laser, scientists have built a new system that generates random numbers fast and at scale.
