Notes:
Researchers using South Africa’s MeerKAT radio telescope detected a loud gravitational wave background through the MeerKAT Pulsar Timing Array. The gravitational wave background’s “hot spot” in the Southern Hemisphere was mapped in unprecedented detail. MeerKAT is a radio telescope array in Northern Cape, South Africa, originally called the Karoo Array Telescope (KAT). Initially planned with 20 receptors, it was expanded to 64 receptors and renamed “MeerKAT,” meaning “more of KAT.” It is part of South Africa’s contribution to the global Square Kilometre Array (SKA) project, the world’s largest radio telescope initiative.

Notes:
Google launched the quantum processor ‘Willow,’ advancing quantum computing to solve practical problems. Willow has 105 physical qubits and operates at near absolute zero temperatures (-273.15°C). It features better error correction and faster performance than other quantum computers. The coherence time of Willow’s qubits is around 100 microseconds, improved by error correction. Willow’s architecture enables lower error rates with more qubits. It outperformed classical computers in testing, completing a Random Circuit Sampling task in minutes.
