The Quantum Scaling Problem: Why Error Correction Demands Massive Resources
Building large-scale quantum computers faces a major obstacle: the inherent fragility of qubits and high error rates from decoherence and crosstalk. Quantum error correction offers a path to fault-tolerance but demands a massive overhead, requiring thousands of physical qubits for a single stable logical qubit.

Universe May Have Avoided Destruction Through a 'Cosmic Lockdown'
New research proposes that the universe may have avoided instantaneous destruction shortly after its birth by entering a "cosmic lockdown." This mechanism, driven by quantum Zeno effects and environmental decoherence, stabilizes the universe's energy state, preventing catastrophic decay.
