Classical computers require large memory resources and computational power to simulate quantum circuits with a large number of qubits. Even supercomputers that can store huge amounts of data face a scalability issue in regard to parallel quantum computing simulations because of the latency of data movements between distributed memory spaces. Here, we apply a cache blocking technique by inserting swap gates in quantum circuits to decrease data movements. We implemented this technique in the open…

TLDR
A method for GPU cluster quantum simulation to improve the data locality is introduced, and two schemes for data exchanging are proposed to overcome the high cost of communication between GPUs.
Full-state quantum circuit simulation by using data compression
TLDR
This study develops a hybrid solution by combining the lossless compression and the tailored lossy compression method with adaptive error bounds at each timestep of the simulation, which reduces the memory requirement of simulating the 61-qubit Grover's search algorithm and suggests that the techniques can increase the simulation size by 2~16 qubits for general quantum circuits.
