MIT Prof. Vladan Vuletic, scietific co-founder of QuEra, presented at AQC 2025 in Boston.

The talk demonstrates how optical tweezer arrays enable deterministic single-atom control at scale, achieving:

Key Technical Milestones:

• Two-qubit gate fidelities of ~99.5% (below error correction threshold)
• 96 logical qubits demonstrated with quantum error correction codes
• Continuous atom replenishment maintaining 3,000+ atoms indefinitely
• Novel cavity-based detection and atom shielding techniques
• Arbitrary connectivity through rapid atom transport (not limited to nearest-neighbor like superconducting)

Architecture Highlights:

• Regional design: storage, processing (QPU), readout, and reservoir zones
• Block-parallel atom movement (not individual control lines per qubit)
• Three-state readout: |0⟩, |1⟩, and atom loss detection
• Magic state distillation for non-Clifford gates

Scaling Pathway: The presentation articulates a clear roadmap: 10,000 physical qubits is "a no-brainer," 100,000 within "a couple of years," targeting logical error rates of 10⁻⁶ and beyond.
