Towards an Optimally Distributed Quantum Fourier Transform Circuit
The paper introduces a method for splitting a quantum Fourier transform (QFT) circuit across multiple quantum processors to minimize entanglement costs, which are major sources of error in distributed computing. By using an 'optimal gate-packing' approach, the authors provide an explicit partitioning scheme that respects the natural order of qubit interactions, offering a practical benchmark for building efficient distributed QFT circuits.
