Scientists realize quantum teleportation between remote, non-neighboring nodes in a quantum network. The network employs three optically connected nodes based on solid-state spin qubits. The teleporter is prepared by establishing remote entanglement on the two links, followed by entanglement swapping on the middle node and storage in a memory qubit.

They demonstrate that once successful preparation of the teleporter is heralded, arbitrary qubit states can be teleported with fidelity above the classical bound, even with unit efficiency. These results are enabled by key innovations in the qubit readout procedure, active memory qubit protection during entanglement generation and tailored heralding that reduces remote entanglement infidelities.

Marcus said the Turing test is not a reliable measure of intelligence because humans are susceptible, and machines can be evasive. Philosopher John Searle introduced the Chinese Room Argument that asserts programming a digital computer may make it appear to understand the language but could not produce real understanding. Even if a computer can interpret symbols and provide sensical responses, it can’t be said to be truly “conscious” because it doesn’t really understand what the symbols mean.

Hector Levesque, a computer scientist at the University of Toronto, proposed the Winograd schema challenge in 2011. Ernest Davis, Leora Morgenstern, Charles Ortiz, and Gary Marcus developed the schema further. Hector designed it as an improvement of the Turing test. The test is structured with multiple-choice questions called Winograd schemas.

Winograd schemas were named after Terry Winograd, professor of computer science at Stanford University. It is a pair of sentences whose intended meaning can be flipped by changing just one word. They generally involve unclear pronouns or possessives.
