Researchers Simulate 61-Bit Quantum Computer with Data Compression

Researchers at the University of Chicago and the U.S. Department of Energy’s Argonne National Laboratory used data compression to fit a 61-quantum bit (qubit) simulation of Grover’s quantum search algorithm on a supercomputer with 0.4% error. The researchers also modeled other quantum algorithms with significantly more qubits and quantum gates than previously possible. Although classical quantum-circuit simulation is essential for better understanding the operations and behaviors of quantum computation, the current full-state simulation limit is 48 qubits. This research offers a new tool for scaling quantum-circuit simulation by applying lossless and lossy data compression to the state vectors.
