For years, a French mathematician searched for a proof that a gigantic number is prime. His method is still used 150 years ...

Researchers have calculated the "ninth Dedekind number," which belongs to an exponentially complex series of numbers that define outputs of logical functions based on different spatial dimensions.

Generating a random number might seem like an easy task, but it can be surprisingly difficult — especially if the probability distribution from which the number is drawn is complex. This is often the ...

A quantum random-number generator has been developed that uses classical cryptography to certify that its output was produced by a quantum process. A truly random number is generated by a process ...

A quantum machine has used entangled qubits to generate a number certified as truly random for the first time, demonstrating a handy function that's physically beyond even the most powerful ...

A team including CU PREP researchers and scientists from CU Boulder and NIST have built the first random number generator using quantum entanglement to produce verifiable random numbers. Dubbed CURBy, ...
