Quantum Randomness Could Create a Spoof-Proof Internet
Briefly

Quantum computers are often perceived as potential game changers, but many past claims of quantum advantage have not translated into significant real-world applications. A recent collaboration involving JPMorganChase, Quantinuum, Argonne National Laboratory, Oak Ridge National Laboratory, and the University of Texas at Austin has demonstrated a meaningful quantum advantage by developing a technique for generating certified randomness. This involves using a quantum computer alongside classical supercomputers to produce random numbers that can be reliably used for secure communications, marking a critical development in the field of quantum computing that has direct applications in online security.
The allure of quantum computers lies in their potential to perform tasks impossible for classical computers. However, many claims of quantum advantage have not delivered on practical usefulness.
Recent research led by JPMorganChase and Quantinuum has demonstrated a genuine quantum advantage in generating certified randomness relevant to online security, challenging the narrative of quantum overhype.
