Google has 72-qubits. IBM has 50-qubits. Intel and QuTech have partnered on a 49-qubit chip. Now, Rigetti, one of the first and most forward leaning quantum computing commercializers is working on a 128-qubit machine. The company is building the new machine on scalable qubit rings composed of two connected 8-qubit rings. Additional work at Rigetti is looking to sharpen focus on quantum computing software; particularly in the areas of machine learning and quantum system optimization.
