Quantum teleportation

노트

말뭉치

1. for the first time, a team of scientists and researchers have achieved sustained, high-fidelity ‘quantum teleportation’ — the instant transfer of ‘qubits’, the basic unit of quantum information.
2. the quantum teleportation of a qubit is achieved using quantum entanglement, in which two or more particles are inextricably linked to each other.
3. We can debate whether ‘quantum teleportation’ as a term is a catchy way of conveying a scientific idea, or a misleading bit of hype.
4. A common view is that quantum teleportation is a new way of transmitting information: a kind of high-speed quantum Wi-Fi.
5. So the real marvel of what we call quantum teleportation is not so much what we can do with it as a technology, but what it reveals about the deep quantum structure of the world.
6. Quantum teleportation is a demonstration of what Albert Einstein famously called “spooky action at a distance”—also known as quantum entanglement.
7. Quantum teleportation is an important means for transmitting information in quantum computing.
8. In order to demonstrate quantum teleportation using electrons, the researchers harnessed a recently developed technique based on the principles of Heisenberg exchange coupling.
9. The quantum teleportation of a qubit is achieved using quantum entanglement, in which two or more particles are inextricably linked to each other.
10. Here, we report the demonstration of chip-to-chip quantum teleportation and genuine multipartite entanglement, the core functionalities in quantum technologies, on silicon-photonic circuitry.
11. Quantum teleportation is a technique for transferring quantum information from a sender at one location to a receiver some distance away.
12. While teleportation is commonly portrayed in science fiction as a means to transfer physical objects from one location to the next, quantum teleportation only transfers quantum information.
13. Understanding quantum teleportation requires a good grounding in finite-dimensional linear algebra, Hilbert spaces and projection matrixes.
14. On 29 May 2014, scientists announced a reliable way of transferring data by quantum teleportation.
15. The name quantum teleportation brings to mind a technology out of Star Trek, where “transporters” can “beam” macroscale objects—even living humans—between far-distant points in space.
16. In quantum teleportation, the states of two entangled particles are what is transported—for instance, the spin of an electron.
17. If Alice wants to send Bob a message via quantum teleportation, she has to accompany it with classical information transported via photons—at the speed of light but no faster.
18. Oddly enough, quantum teleportation may also have important utility for secure communications in the future, and much of the research is funded with cybersecurity applications in mind.
19. He has authored more than 44 papers in leading technical journals and conferences, which includes the first realization of continuous-variable quantum teleportation.
20. “The first quantum teleportation took place in laboratory conditions.
21. Quantum teleportation is a demonstration of what Albert Einstein famously called "spooky action at a distance" -- also known as quantum entanglement.
22. But while teleportation in science fiction films often ignores physical laws, quantum teleportation works just because of that.
23. Performing quantum teleportation means that a quantum state disappears on one side and then reappears again at the other side.
24. Quantum repeaters use this concept of quantum teleportation.
25. Quantum teleportation is based on a hypothesis described in 1935 by physicist Albert Einstein and his colleagues Boris Podolsky and Nathan Rosen, known as the EPR paradox.
26. Since 1998, various experiments have achieved this quantum teleportation, initially using individual photons, then atoms and more complex systems.
27. However, it is essential to stress that quantum teleportation does not serve to transmit data instantaneously, or at faster than light speed.
28. But despite this limitation, the possibilities of quantum teleportation look more and more promising as new milestones are reached.
29. It has been known since the 1990s that multidimensional quantum teleportation is theoretically possible.
30. The core of quantum teleportation is the so-called Bell measurement.
31. The participating Chinese researchers also see great opportunities in multidimensional quantum teleportation.
32. Scientists are only beginning to understand the mysteries of entanglement and how it makes quantum teleportation possible.
33. Namely, in quantum teleportation, the entanglement in the Bell state (EPR pair) is used to transport an arbitrary quantum state |ψ〉 between two distant observers A and B (often called Alice and Bob).
34. Quantum teleportation is one of the most striking consequence of quantum mechanics and is defined as the transmission and reconstruction of an unknown quantum state over arbitrary distances.
35. Quantum teleportation allows the state |ϕ〉 to be transmitted with the aid of an EPR pair and classical communication.
