Platform class 1 — Trapped ions

Barreiro2011 (arXiv:1104.1146, Nature 470, 486 (2011))

Title: "An Open-System Quantum Simulator with Trapped Ions" (matches bib). Verbatim (abstract):

"Using a quantum computing architecture with trapped ions, we combine multi-qubit gates with optical pumping to implement coherent operations and dissipative processes. We illustrate this engineering by the dissipative preparation of entangled states ..." Confirms dissipative-engineering entanglement in trapped ions. CONFIRMED.

Lin2013 (arXiv:1307.4443, Nature 504, 415 (2013))

Title: "Dissipative production of a maximally entangled steady state" (matches bib "... of two quantum bits"). Verbatim (abstract):

"Here, on the contrary, we combine unitary processes with engineered dissipation to deterministically produce and stabilize an approximate Bell state of two trapped-ion qubits independent of their initial state. ... we implement the process in a continuous time-independent fashion, analogous to optical pumping of atomic states ..." Confirms dissipative-engineering entanglement in trapped ions. CONFIRMED.

Platform class 2 — Atomic ensembles

Krauter2011 (arXiv:1006.4344, PRL 107, 080503 (2011))

Title: "Entanglement generated by dissipation and steady state entanglement of two macroscopic objects" (matches bib). Verbatim (abstract):

"Here we report on an experiment, where dissipation continuously generates entanglement between two macroscopic objects. This is achieved by engineering the dissipation using laser- and magnetic fields ... Our system consists of two ensembles containing about 10^12 atoms ..." Confirms dissipative-engineering entanglement in atomic ensembles. CONFIRMED.

Platform class 3 — Superconducting circuits

Shankar2013 (arXiv:1307.4349, Nature 504, 419 (2013))

Title: "Stabilizing entanglement autonomously between two superconducting qubits" (matches bib variant "Autonomously stabilized entanglement between two superconducting quantum bits"). Verbatim:

"Here we demonstrate the stabilization of an entangled Bell state of a quantum register of two superconducting qubits for an arbitrary time. Our result is achieved by an autonomous feedback scheme which combines continuous drives along with a specifically engineered coupling between the two-qubit register and a dissipative reservoir." Confirms dissipative (engineered-reservoir) entanglement in superconducting circuits. CONFIRMED.

Liu2016 (arXiv:1509.00860, PRX 6, 011022 (2016))

Title: "Comparing and combining measurement-based and driven-dissipative entanglement stabilization" (matches bib). Verbatim (abstract):

"This platform [two superconducting qubits coupled to a cavity] is used to stabilize entanglement by two nominally distinct schemes: a 'passive' reservoir engineering method and an 'active' correction based on conditional parity measurements." Confirms driven-dissipative (reservoir-engineering) entanglement stabilization in superconducting qubits. CONFIRMED.

Kimchi-Schwartz2016 (arXiv:1511.00702, PRL 116, 240503 (2016))

Title: "Stabilizing entanglement via symmetry-selective bath engineering in superconducting qubits" (matches bib). Verbatim (abstract):

"Here, we demonstrate dissipative stabilization of entanglement between two superconducting transmon qubits in a symmetry-selective manner. We utilize the engineered symmetries of the dissipative environment to stabilize a target Bell state ..." Confirms dissipative (bath-engineering) entanglement in superconducting qubits. CONFIRMED.

Judgment

All six cited works, across all three platform classes, were fetched as full text and each verbatim passage explicitly reports an experimental demonstration of entanglement via dissipative/reservoir/bath engineering in the stated platform. The multi-reference attribution is fully supported.

VERDICT: verified (no limitations; all classes confirmed by full-text, not abstract-only — the quoted passages are the authors' own abstract/intro statements within the full fetched papers).
