For decades, the dream of building a functioning quantum computer has been both tantalizingly close and frustratingly out of reach. The technology promises transformative advances in computation—solving problems in chemistry, cryptography, optimization, and artificial intelligence that are beyond the reach of even the most powerful supercomputers. Yet the road to scalable quantum computing has been littered with obstacles, largely because quantum bits (qubits) are notoriously fragile.
