AtomQ is developing a scalable atomic quantum computer using optically active quantum defects created with scanning transmission electron microscopy. Their platform generates precise qubits rapidly, enabling the construction of large qubit arrays in a compact device. Current quantum computers, with around 1,000 qubits, use architectures like trapped ions and superconducting circuits, but practical applications in fields like energy, pharmaceuticals, finance, and cryptography require at least 1 million qubits. Scalability remains a major challenge. AtomQ is part of the 2024 Innovation Crossroads cohort.
