On-chip cryptographic protocol lets quantum computers self-verify results amid hardware noise

Phys.org highlights recent work by Dr. Cica Gustiani and Prof. Elham Kashefi on a cryptographic protocol enabling quantum computers to self-verify their outputs. Successfully implemented on Quantinuum’s trapped-ion quantum processing unit, this collaboration with the University of Edinburgh’s Quantum Software Lab represents a key step toward trustworthy quantum computation on near-term devices.

Extract of the article : Over the past few years, researchers have introduced various verification protocols for quantum computing. Most of these solutions, however, were merely theoretical in nature and not applicable to existing quantum processors. “In simple terms, we tried to make quantum computers prove they’re telling the truth,” said Cica. “We took a cryptographic verification protocol that usually requires communication between two devices and made it work entirely on a single chip. The idea is that even if the hardware is noisy or imperfect, it can still verify its own results through built-in tests and randomness.”
