The allure of quantum computers is, at its heart, quite simple: by leveraging counterintuitive quantum effects, they could perform computational feats utterly impossible for any classical computer.

Randomness is incredibly useful. People often draw straws, throw dice or flip coins to make fair choices. Random numbers can enable auditors to make completely unbiased selections. Randomness is also ...

Sometimes you need random numbers — and properly random ones, at that. Hackaday Alum [Sean Boyce] whipped up a rig that serves up just that, tasty random bytes delivered fresh over MQTT. [Sean] tells ...

Using a powerful machine made up of 56 trapped-ion quantum bits, or qubits, researchers have achieved something once thought impossible. They have proven, for the first time, that a quantum computer ...

Quantum computing has been touted as a revolutionary advance that uses our growing scientific understanding of the subatomic world to create a machine with powers far ...

Quantum computers—devices that process information using quantum mechanical effects—have long been expected to outperform classical systems on certain tasks. Over the past few decades, researchers ...

Random number generation is a central process in many applications, including cryptography, security, and scientific simulations. It is the process of generating a series of numbers that cannot be ...

Chip-based device paves the way for scalable and secure random number generation, an essential building block for future digital infrastructure Chip-based device paves the way for scalable and secure ...

Quantum walks sound abstract, but they sit at the center of a very concrete race: who will harness quantum mechanics to solve problems that overwhelm today’s most powerful supercomputers. Instead of ...

A team of researchers have published a paper in which they show that a quantum computer can produce certified randomness, which has numerous application areas such as in cryptography. According to the ...

Quantum spin systems occupy a central role in understanding magnetic phenomena and phase transitions at the microscopic level. In these systems, intrinsic angular momentum (spin) interactions give ...
