• IBM’s Starling Breakthrough — IBM’s new qLDPC error-correction architecture cuts qubit overhead by ~90%, paving the way for fault-tolerant quantum computers within the decade.

• Google’s 105-Qubit Willow Chip — Achieved a 10²⁵× performance edge in random circuit sampling, completing tasks that would take classical supercomputers billions of years.

• Microsoft’s Majorana-1 Processor — First operational topological-qubit chip. Majorana zero modes protect data at the hardware level, drastically reducing decoherence and error rates.

• IonQ Tempo Milestone — Reached an Algorithmic Qubit (AQ) 64 score on its 100-qubit Tempo system—36 quadrillion times more powerful than IBM’s Eagle. Commercial use in energy, finance, and AI expected soon.

• Fujitsu & RIKEN’s 256-Qubit Machine — World-leading superconducting quantum computer with scalable design toward 1,000 qubits by 2026, integrating with Japan’s supercomputer Fugaku for hybrid workflows.

• China’s Zuchongzhi-3 Quantum Leap — 105-qubit superconducting chip performed computations 10¹⁵× faster than the fastest supercomputer, showcasing exponential quantum advantage.

• Amazon’s Ocelot Chip — AWS built a bosonic “cat qubit” system improving coherence stability by 30%, proving quantum error correction can scale efficiently in cloud-based setups.

• Bosonic “Cat Qubits” Rise — Schrödinger’s-cat-inspired qubits now hold quantum states longer while needing fewer resources, reducing error rates from 1.75% to 1.65% per cycle.

• Pasqal’s 2025 Roadmap — Neutral-atom computing startup plans 20 logical qubits by 2027 using optical tweezers, accelerating progress toward true fault-tolerance.

• The Convergence — From IBM’s codes to Microsoft’s hardware to Google’s speed, 2025 marks the dawn of practical quantum scaling. The race is no longer “if,” but how fast.
