Information Constraints for Scalable Control in a Quantum Computer

The complexity of qubit control places size constraints on the control system. When working to understand quantum systems engineering, there are many constraints to building a scalable quantum computer. Here I discuss a constraint on the qubit control system from an information point of view, showing that the large amount of information needed for the

Quantum supremacy using a programmable superconducting processor

The promise of quantum computers is that certain computational tasks might be executed exponentially faster on a quantum processor than on a classical processor1 . A fundamental challenge is to build a high-fdelity processor capable of running quantum algorithms in an exponentially large computational space. Here we report the use of a processor with programmable
