Dmytro Kundys, Francesco Graffitti, Richard A. McCracken +2
The future of quantum photonic technology depends on the realization of efficient sources of single photons, the ideal carriers of quantum information. Parametric downconversion (P…
Measurement Device Independent Verification of Quantum Channels
Francesco Graffitti, Alexander Pickston, Peter Barrow +5
The capability to reliably transmit and store quantum information is an essential building block for future quantum networks and processors. Gauging the ability of a communication…
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…
Photovoltaic effect and photopolarization in Pb[(Mg1/3Nb2/3)0.68Ti0.32]O3 crystal
A. S. Makhort, F. Chevrier, D. Kundys +2
Ferroelectric photovoltaic materials are an alternative to semiconductor-based photovoltaics and offer the advantage of above bandgap photovoltage generation. However, there are fe…
