Researchers find way to generate quantum random numbers on cloud
Researchers at Bengaluru's Raman Research Institute have figured out how to generate certified quantum random numbers right on cloud-based quantum computers.
Their new approach swaps out the old, complex methods for a simpler one using the Leggett-Garg inequality, which just tracks a single quantum particle over time—making it much more practical for today's tech.
The protocol works even on noisy quantum computers
The team's protocol uses low-depth circuits and single-qubit gates, so it works even on noisy quantum computers you can access online (like IBMQ).
Their experiments matched theory and showed strong results, building on their 2022 work that closed key loopholes and set the stage for real-world randomness certification.
Certified quantum randomness can't be guessed by anyone
Random numbers are crucial for things like secure passwords and data encryption—but classical computers can't make truly unpredictable ones.
This certified quantum randomness can't be guessed by anyone (even with quantum tech), helping keep your personal info and future digital life safe from hacks.
