Solving approximate hidden subgroup problems: quantum heuristics to detect weak entanglement
Petar Simidzija, Eugene Koskin, Elton Yechao Zhu +2
How can we use a quantum computer to detect the entanglement structure of a quantum state? Bouland et al. (2024) recently provided an algorithm that, given multiple input copies of…
Learning to Utilize Correlated Auxiliary Noise: A Possible Quantum Advantage
Aida Ahmadzadegan, Petar Simidzija, Ming Li +1
This paper has two messages. First, we demonstrate that neural networks that process noisy data can learn to exploit, when available, access to auxiliary noise that is correlated w…
Superadditivity of channel capacity through quantum fields
Koji Yamaguchi, Aida Ahmadzadegan, Petar Simidzija +2
Given that any communication is communication through quantum fields, we here study the scenario where a sender, Alice, causes information-carrying disturbances in a quantum field.…
Transmission of quantum information through quantum fields
Petar Simidzija, Aida Ahmadzadegan, Achim Kempf +1
We investigate the quantum channel consisting of two localized quantum systems that communicate through a scalar quantum field. We choose a scalar field rather than a tensor or vec…
Harvesting correlations from thermal and squeezed coherent states
Petar Simidzija, Eduardo Martin-Martinez
We study the harvesting of entanglement and mutual information by Unruh-DeWitt particle detectors from thermal and squeezed coherent field states. We prove (for arbitrary spatial d…
Non-perturbative analysis of entanglement harvesting from coherent field states
Petar Simidzija, Eduardo Martin-Martinez
We study (non-perturbatively) the interactions of delta-coupled detectors with coherent states of a scalar field. We show that the time-evolved density matrix spectra of i) a singl…
