Scaling quantum computers requires one to solve a difficult I/O problem. Since quantum information does not fan out, the controller channel count is required to scales as the number of qubits, typically requiring thousands of channels to drive 1000 solid state qubits. Optically addressed qubits such as atom or ion arrays can multiplex qubit drive channels by making use of qubit transport, but still require hundreds of individually modulated laser beams to drive several thousand qubits. Today we show a scalable qubit control system capable of driving and reading out thousands of qubits. The OPX1000 control system is scalable to several thousands of channels, enough to drive the largest solid state QPUs imagined today. To bridge the I/O gap for optically addressed qubits as well, we present in collaboration with QuEra computing a SiN photonic platform that extends the OPX1000 to the THz regime and allows one to deliver hundreds of individually modulated laser beams to drive many thousands of atom qubits. As the number of degrees of freedom rapidly increases, ML techniques will be necessary to find optimal drive parameters for large scale qubit systems. DGX Quantum, a new quantum-classical compute platform developed in collaboration with NVidia will help close the loop and deliver optimal drive and readout signals even as systems scale to thousands of qubits.
