Quantum Computing Meets AR: From Qubit Milestones to Reality Check

2014–2016: researchers reached a surface-code threshold, demonstrated a four-qubit error-detection code, and extended qubit lifetime through error correction.

2018 framed 50–100 qubits as NISQ; 2019’s Sycamore sampled random circuits on 53 qubits.

Specific 2020–2025 qubit milestones were not verified in the retrieved evidence.

AR’s future quantum role is a hybrid, selective accelerator for matching or optimisation, not continuous perception or rendering.
