Quantum Entanglement & Entanglement Sudden Death

• Context (PIB): Researchers from Raman Research Institute (RRI), Calgary, and LSU developed a well-timed flip operation using optical waveplates to prevent Entanglement Sudden Death.
• Core Phenomenon: Entanglement intertwines quantum states regardless of spatial distance, but environmental decoherence causes rapid decay or abrupt complete disappearance before full physical relaxation.
• National Quantum Mission (NQM): Funded partially under DST's NQM, this hardware-free timing mechanism advances quantum computing, Quantum Key Distribution (QKD), and high-precision sensing.
• Historical Milestones: Conceptualized in the 1935 EPR Paradox (Einstein-Podolsky-Rosen) and experimentally validated by Nobel Laureates Aspect, Clauser, and Zeilinger (2022).

National Commission for Safai Karamcharis (NCSK)

• Context (PIB): Shri Bhagwat Prasad Makwana was appointed Chairperson of NCSK under the Ministry of Social Justice and Empowerment.
• Statutory Evolution: Established as a statutory body via NCSK Act, 1993, it became a non-statutory body in 2004 following the Act’s lapse.
• Constitutional & Legal Linkage: Monitors implementation of PEMSR Act, 2013 to eradicate manual scavenging, aligning with Article 21 (Right to Dignity).
• Institutional Composition: Comprises 1 Chairperson (Minister of State rank), 1 Vice-Chairperson, and 5 Members appointed via executive resolution.

Gollala Gudi Temple

• Context (NOA): The Archaeological Survey of India (ASI) notified the 12th–13th century Kakatiya-era Gollala Gudi Temple at Palampet (Mulugu, Telangana) as a Monument of National Importance.
• Architectural Layout: Located southwest of the UNESCO-listed Ramappa Temple, it exhibits a Trikutalaya (triple-sanctum) layout around a central east-facing mandapa, following Deccan/Vesara styling.
• Engineering & Iconography: Built with interlocked dry masonry on a Kakatiya sandbox foundation for earthquake resilience; houses a primary Shiva Lingam with niches showing Vishnu, Lakshmi, Ganesha, and Mahishasuramardini.
• Statutory Governance: Protected under the AMASR Act, 1958, enforcing a 100-meter prohibited zone and a 200-meter regulated zone under National Monuments Authority (NMA) oversight.

China’s Mega Dam on the Yarlung Zangbo (Brahmaputra)

• Context (TH): Beijing reaffirmed its commitment to constructing the Medog Hydropower Station at the Great Bend in Tibet, despite recent glacial flash floods and seismic risks along the China-Nepal border.
• Project Scale: Planned at 60 GW capacity via five cascade stations, it will produce ~300 billion kWh annually—triple the capacity of the Three Gorges Dam.
• Geological Hazards: Sits near active tectonic fault lines (e.g., Paizhen Fault) in the high-seismicity Himalayan collision zone, exacerbating risks of Glacial Lake Outburst Floods (GLOFs) and reservoir-induced earthquakes.
• Geopolitical & Transboundary Risks: Enables upper-riparian control over downstream flows into India (Siang/Brahmaputra) and Bangladesh (Jamuna) without a binding multilateral water-sharing agreement.
