Linear-optical test of quantum contextuality with sequential measurements
Jiaqi Liu, Bita Olamaei, Lijian Zhang +2
Quantum contextuality provides a fundamental signature of nonclassical behavior that cannot be explained by noncontextual hidden-variable models. We propose and experimentally impl…
Information Scrambling in Bosonic Gaussian Dynamics
Ali Mollabashi, Saleh Rahimi-Keshari
We investigate the dynamics of information scrambling in bosonic systems undergoing Gaussian unitary evolution associated with quadratic Hamiltonians. For initial Gaussian states,…
Decoherence time of the ground state spin of centers in hexagonal boron nitride
Fatemeh Tarighi Tabesh, Saleh Rahimi-Keshari, Mehdi Abdi
The ground-state spin of optically active defects in hexagonal boron nitride (hBN) offers a promising platform for quantum information applications, such as qubits for quantum comp…
Measurement incompatibility under loss
Mohammad Mehboudi, Fatemeh Rezaeinia, Saleh Rahimi-Keshari
We investigate the measurement incompatibility of continuous-variable systems with infinite-dimensional Hilbert spaces under the influence of pure losses, a fundamental noise sourc…
Phase-space negativity as a computational resource for quantum kernel methods
Ulysse Chabaud, Roohollah Ghobadi, Salman Beigi +1
Quantum kernel methods are a proposal for achieving quantum computational advantage in machine learning. They are based on a hybrid classical-quantum computation where a function c…
