New 28-Pixel Parallel SNSPD Design Achieves Breakthroughs in Photon-Number Resolution and Ultra-Fast Detection

July 23, 2024
Researchers from ID Quantique and the University of Geneva have made a significant advancement in superconducting nanowire single-photon detector (SNSPD) technology. A new 28-pixel parallel SNSPD (P-SNSPD) combines state-of-the-art photon-number resolution (PNR) and ultra-high-speed performance.

USTC Unveils Connection of Randomness and Nonlocality in Multiple-Input and Multiple-Output Quantum Scenario

USTC Unveils Connection of Randomness and Nonlocality in Multiple-Input and Multiple-Output Quantum Scenario

April 8, 2025
Recently, researchers from the University of Science and Technology of China (USTC) reveals that not all forms of quantum nonlocality guarantee intrinsic randomness. They demonstrated that violating two-input Bell inequalities is both necessary and sufficient for certifying randomness, but this equivalence breaks down in scenarios involving multiple inputs. This finding has been published in Physical Review Letters.

Photon Detectors Rewrite the Rules of Quantum Computing

Photon Detectors Rewrite the Rules of Quantum Computing

February 28, 2024
Scientists at Paderborn University have used a new method to determine the characteristics of optical, i.e. light-based, quantum states. For the first time, they are using certain photon detectors — devices that can detect individual light particles — for so-called homodyne detection. The ability to characterize optical quantum states makes the method an essential tool for quantum information processing. Precise knowledge of the characteristics is important for use in quantum computers, for example. The results have now been published in the specialist journal Optica Quantum.
