JPMorgan Chase has announced a significant advancement in quantum computing, centered around the generation of certified randomness.
In a recent publication in Nature, researchers articulated that achieving "Certified Quantum Randomness" marks a transformative step, allowing theoretical concepts to transition into practical applications for quantum computing. This breakthrough has far-reaching implications for the financial services sector, enhancing security protocols and trading strategies that rely on true randomness.
The research team collaborated with experts from Quantinuum, Argonne National Laboratory, Oak Ridge National Laboratory, and the University of Texas at Austin. Together, they successfully demonstrated a new quantum computing protocol for generating Certified Randomness.
The protocol involves two key stages. Initially, the researchers created challenge random circuits, which were then transmitted to an untrusted remote quantum computer tasked with returning the corresponding samples. The response time was so rapid that the challenge circuits could not be replicated using classical simulation techniques within the same timeframe. This was validated against the most advanced supercomputers available today.
In the second stage, the randomness generated was mathematically verified using classical supercomputers, ensuring that it could not be replicated by classical means.
Marco Pistoia, Head of Global Technology Applied Research and Distinguished Engineer at JPMorgan Chase, remarked, “This achievement represents a significant milestone in quantum computing, providing a solution to real-world challenges that exceed the capabilities of conventional supercomputers.” He emphasized that the development of Certified Randomness not only indicates progress in quantum hardware but is also crucial for future research in areas like statistical sampling, numerical simulations, and cryptography.
