Quantum Quenches and Entanglement [PDF]
, 2017 A simple but quite non-trivial class of non-equilibrium processes of a quantum many-body system is quantum quenches. We start with a ground state \(\mid \!\Phi _{0}\rangle\) of a certain Hamiltonian H0. At time t = 0, we suddenly change the Hamiltonian from H0 to a new one H.

Entanglement cost of quantum channels [PDF]
2012 IEEE International Symposium on Information Theory Proceedings, 2012 The entanglement cost of a quantum channel is the minimal rate at which entanglement (between sender and receiver) is needed in order to simulate many copies of a quantum channel in the presence of free classical communication. In this paper we show how to express this quantity as a regularised optimisation of the entanglement formation over states ...

Quantum entanglement of the spin and orbital angular momentum of photons using metamaterials
Science, 2018 Going quantum with metamaterials Metasurfaces should allow wafer-thin surfaces to replace bulk optical components. Two reports now demonstrate that metasurfaces can be extended into the quantum optical regime. Wang et al.

Achieving Chemical Recognition, Recycling, and Circularity With Radical Nanostructures
Advanced Functional Materials, EarlyView.Here, innovative 3D radical nanostructures based on 4,4′‐dicyano‐2,2′‐biphenylene‐fused tetrazolinyl radical, fabricated on interdigitated gold‐SiO2 hybrid surfaces are presented. They retain their magnetic properties, their morphology and size can can tune, selectively remove them from specific substrate regions using distilled water, and return the ...

Physical Review ResearchQuantum algorithms reformulate computational problems as quantum evolutions in a large Hilbert space. Most quantum algorithms assume that the time evolution is perfectly unitary and that the full Hilbert space is available.

Optimal quantum network decongestion strategies
Scientific Reports, 2023 This study clarifies the problem of decongestion in quantum networks, with a specific focus on the crucial task of entanglement distribution. Entangled particles are a valuable resource in quantum networks, as they are used for most quantum protocols. As

Advanced Functional Materials, EarlyView.This work reports the self‐assembly of a pyrene derivative into two distinct nanostructures and their application in visible‐light photocatalysis. The two nanostructures exhibit completely different yet complementary photocatalytic activities, promoting either H2 or H2O2 evolution.
