Google Quantum AI Cuts Qubit Needs 20-Fold as Ackman Allocates 39% in $17.7B Fund
Google Quantum AI’s paper cut qubit requirements 20-fold for breaking encryption, analysts warn scaling to the thousands of qubits needed to threaten Bitcoin takes years. Bill Ackman’s Pershing Square invested 39% of its $17.7B portfolio in three stocks including Alphabet, signaling institutional support for its AI and cloud expansion.
1. Google Quantum AI Cuts Qubit Requirements
Google Quantum AI published a paper demonstrating a 20-fold reduction in qubit requirements to break encryption. Analysts caution that scaling from tens to thousands of logical qubits remains a multi-dimensional engineering challenge likely to take years, providing a 3–5-year window for post-quantum security upgrades.
2. Pershing Square Allocates 39% of Portfolio to Alphabet
Bill Ackman’s Pershing Square invested 39% of its $17.7 billion stock portfolio across Brookfield, Uber and Alphabet. The sizable allocation to Alphabet highlights investor confidence in its AI capabilities, cloud computing growth and custom processor roadmap, supporting its long-term valuation.
