Ion trap

노트

말뭉치

1. Many traditional ion trapping research groups have made the transition to quantum computing research, while, more recently, many other new research groups have joined the effort.
2. At this very low temperature, vibrational energy in the ion trap is quantized into phonons by the energy eigenstates of the ion strand, which are called the center of mass vibrational modes.
3. It is therefore necessary to design interconnected ion traps that are capable of transferring information from one trap to another.
4. Semiconductor fabrication techniques have also been employed to manufacture the new generation of traps, making the 'ion trap on a chip' a reality.
5. Some of the resulting ions will, by chance, happen to lie inside our ion trap.
6. Here is a picture of the first ion trap electrode structure to be used in our lab (it dates from 1999 - a similar structure has since been donated to the Science Museum, London).
7. The ion trap provides a harmonic potential well.
8. We apply a fixed external magnetic field of around 100 Gauss (0.01 Tesla) to the whole ion trap.
9. Ion trapping and cooling were well-known technologies, allowing the ions to be isolated from the environment and their motion frozen out.
10. In 1995, Cirac and Zoller came up with the blueprint for an ion trap quantum computer, and circuit-based quantum computer architecture in general.
11. Of the many divergent approaches to building a practical quantum computer, one of the most promising paths leads toward ion traps.
12. Scientists at the Joint Quantum Institute (JQI) have been steadily improving the performance of ion trap systems, a leading platform for future quantum computers.
13. They used laser pulses to simultaneously create quantum connections between different pairs of qubits—the first time these kinds of parallel operations have been executed in an ion trap.
14. Ion traps are devices for capturing charged atoms and molecules, and they are commonly deployed for chemical analysis.
15. In recent decades, physicists and engineers have combined ion traps with sophisticated laser systems to exert control over single atomic ions.
16. We present the blueprint for a scalable microwave trapped ion quantum computer module, which is based on today’s silicon semiconductor and ion trap technology.
17. The concept of using ion transport on microfabricated trap arrays to realize an ion trap quantum computer was proposed by Kielpinski et al.
18. ( 10 ), where ion trap modules, also called elementary logic units, are photonically interconnected using commercial fibers and optical cross-connect switches.
19. This proposal demonstrates that going from one to many modules is within reach of current technology and thereby provides an interesting path to a large-scale ion trap quantum computer.
20. Some of the key founders (Jungsang Kim and Christopher Monroe) had been doing research on ion traps for years at Duke and the University of Maryland before launching the company.
21. “In collaboration with the University of Maryland, we have designed and constructed several generations of fully-programmable ion trap quantum computers,” said Kim.
22. Fast forward to March when Honeywell announced plans to introduce an ion trap-based quantum computer whose ‘performance’ would rival any other quantum computer now available.
23. Research into using ion trap technology for quantum computing has simmered for years.
24. Broadly (and with apologies for garbling), ion trap uses ions as qubits.
25. There is an NSF program (STAQ) exploring ion technology for quantum computing and IonQ is a start-up also developing an ion trap machine and also touting superior performance.
26. Our aim is to develop new quantum technologies, in particular, the ion trap quantum computer.
27. For this purpose our research focuses on applied experimental quantum information science, development of new scalable methods to build ion trap arrays and the generation of large scale entanglement.
28. IonQ is the first company pursuing ion trap quantum computing systems, although Honeywell has recently started a notable effort.
29. The H1, as it’s called, is actually the same ion trap chip the company debuted as a prototype, but with four additional ions.
30. Ion trap quantum computers are made of chips that are designed to trap and hold ions in a line using a specially-designed RF electromagnetic field.
31. Light is used for virtually everything in an ion trap quantum computer – ionizing the atoms, cooling them down, controlling the quantum state and finally reading it out.
32. With only minor adjustments these modules are also suitable for alternative ion trap quantum computer architectures, such as schemes using photonic interconnects.
33. The researchers commissioned a commercial foundry to produce chips which contain both gold electrodes for the ion traps and, in a deeper layer, waveguides for laser light.
