TELEPORTATION - PART 4

QUANTUM COMPUTING

What has been set out in Part 2 of this series can be done in the first instance with the information.

In a Trapped ion quantum computer, ions (or charged atomic particles), can be confined and suspended in free space using electromagnetic fields. Qubits (quantum bit) are stored in stable electronic states of each ion, and quantum information can be processed and transferred through the collective quantized motion of the ions in the trap (interacting through the Coulomb force). Lasers are applied to induce coupling between the qubit states (for single qubit operations) or coupling between the internal qubit states and the external motional states (for entanglement between qubits). The fundamental operations of a quantum computer have been demonstrated experimentally with high accuracy (or "high fidelity" in quantum computing language) in trapped ion systems and a strategy has been developed for scaling the system to arbitrarily large numbers of qubits by shuttling ions in an array of ion traps. This makes the trapped ion quantum computer system one of the most promising architectures for a scalable, universal quantum computer.

How we might exploit the ability to teleport energy isn’t clear yet says Hotta. But the really exciting stuff is the implications this has for the foundations of Physics. Hotta says that his approach gives physicists a way of exploring the relationship between quantum information and quantum energy for the first time. There is a growing sense that the properties of the Universe are best described not by the laws that govern matter but by the laws that govern information.

This, that appears to be true for the quantum world is certainly true for special relativity, and it is currently being explored for general relativity. Having a way to handle energy on the same footing may help to draw these diverse strands together.
