Enhanced Multi-Qubit Phase Estimation in Noisy Environments by Local Encoding
Massimiliano Proietti, Martin Ringbauer, Francesco Graffitti +7
The first generation of multi-qubit quantum technologies will consist of noisy, intermediate-scale devices for which active error correction remains out of reach. To exploit such d…

Experimental test of local observer-independence
Massimiliano Proietti, Alexander Pickston, Francesco Graffitti +5
The scientific method relies on facts, established through repeated measurements and agreed upon universally, independently of who observed them. In quantum mechanics, the objectiv…
