Steady-state entanglement of two atoms created by classical driving
... and even when one of them becomes zero, the other can still give rise to entanglement 共see Fig. 2兲. The deviation from the Lamb-Dicke limit decreases the cooperation effects, thus decreases steady-state entanglement. Summarizing, we have examined the system of two identical two-level atoms, interact ...

Demonstration of Entanglement of Electrostatically Coupled Singlet-Triplet Qubits M. D. Shulman
... To further understand the evolution of the quantum state, we focus on one value of J and compare the measured Pauli set to that expected from single-qubit dephasing rates and J 12 (see supplemental information). Fig. 3a shows the Pauli set for the measured and expected quantum states for τ =40ns, wh ...

Superposition, Entanglement, and Raising Schrödinger’s Cat Nobel Lecture, December 8, 2012
... Schrödinger dubbed this an entangled state because the state of the particle is correlated with the state of the cat. That is, upon measurement, if the particle is observed to be undecayed, one can say with certainty that the cat is alive, and vice versa. But before measurement, the particle and cat ...
