Quantum Computing's Error Mitigation Breakthroughs

Researchers at IBM Quantum and UC Berkeley have shown that error mitigation techniques can give quantum computers an edge over classical supercomputers in some common physics calculations. The team pitted a 127-qubit quantum computer against a state-of-the-art supercomputer and, for at least one type of calculation, bested the supercomputer. The calculation could be made increasingly complex to test whether today's noisy, error-prone quantum computers can produce accurate results for certain types of common calculations. The results provide hope that quantum computing algorithms with error mitigation could tackle cutting-edge physics problems.
