The Future of Quantum Computing Is Modular
4 min read Edd Gent is a Contributing Editor for IEEE Spectrum. Nicholas Little Quantum-computing companies have been competing for years to squeeze the most qubits onto a chip. But fabrication and connectivity challenges mean there are limits to this strategy. The focus is now shifting to linking multiple quantum processors together to build computers large enough to tackle real-world problems. In January, the Canadian quantum-computing company Xanadu unveiled what it says is the first
