"Breakthrough: Scientists Create Quantum Correlation Test Free from Randomness"

Scientists have developed a semi-device independent, randomness-free test for quantum correlations and non-projective measurements. The test eliminates the need for seed randomness, which is required in traditional quantum tests. The researchers demonstrated the test using entangled photons and showed that the shared randomness acquired from entangled coins cannot be replicated using classically correlated coins. This discovery has implications for quantum communication protocols and quantum information processing. The study offers a proof of concept for a new approach to certifying non-classicality in a semi-device independent manner.

Advancements in Photonic Chip Pave the Way for Scalable Quantum Simulations

Researchers at the University of Rochester have developed a chip-scale optical quantum simulation system that could enable computers to simulate complex natural phenomena at the quantum level. By controlling the frequency of quantum entangled photons, the team created a synthetic space that mimics the physical world, allowing for more intricate simulations. This approach reduces the physical footprint and resource requirements compared to traditional photonics-based computing methods. The researchers believe this system can serve as a basis for scaling up to more complex simulations and computation tasks in the future.
