⚛️ Quantum: Microsoft Majorana 1 & Logical Qubits
Microsoft is scaling its Majorana 1 quantum chip, the first to successfully leverage topological qubits for fault tolerance. In collaboration with Quantinuum, the team demonstrated 12 entangled logical qubits with record fidelity. This milestone moves quantum computing from experimental physics to commercial Azure Quantum availability for chemistry and material science. Read Quantum Deep-Dive →
🔐 Security: The RSA-2048 Threshold Alert
A bombshell study from Caltech and Google Quantum AI suggests that RSA-2048 encryption could be broken with just 500,000 physical qubits. This is a 20x reduction from previous estimates, effectively accelerating the Q-Day timeline. The research has triggered an emergency push for Post-Quantum Cryptography (PQC) across global financial systems. Read Security Alert →
🎙️ Media: OpenAI Acquires Tech Talk Show TBPN
In a major strategic shift, OpenAI has acquired the Technology Business Programming Network (TBPN). The move signals a pivot toward direct media ownership to shape the global narrative around AGI and regulation. TBPN will continue to operate with editorial autonomy but will integrate OpenAI's generative voice and video tools. Read Media Strategy →
