A mixed team of researchers from the Quantum Engineering Technology Labs (University of Bristol) and the Technical University of DTU has achieved an essential landmark in the field of quantum teleportation. Previous progress related to chip-based applications has been recorded in the past, but the latest one is quite major.
Many publications and studies have explored the possibilities offered by the development of quantum computer processors. However, a more significant focus should be placed on quantum entanglement, a process that could boost the speed at which data is transferred.
Quantum entanglement is an exciting phenomenon that remained elusive for an extended period. It can be described briefly as such: quantum particles which are paired will share the same position, momentum, speed, and polarization regardless of how long is the distance between them. This manifestation has been encountered among photons, electrons, and bigger molecules.
Recent data has shown that quantum entanglement can work over a small distance, for example, in a single chip. An impressive speed of up to 1,200 kilometers has been achieved with the help of a satellite.
Scientists Tested a New Method for Quantum Teleportation
The team of researchers has constructed a silicon photonic chip that can execute chip-to-chip quantum teleportation. Quantum information is stored in photons that are generated within the circuits and can travel at an impressive speed. Data has been transferred without problems between two programmable chips of this type.
A stable entanglement link was recorded among the two chips as photons present in both units shared a single quantum state.
Besides several smaller tests, a two-chip teleportation experiment took place as that quantum state of an individual particle was sent among the two chips after a single measurement tool place.
It is worth noting that the entanglement is not 100% stable, but a high-fidelity rate of 91% was recorded. Quantum hardware that could perform advanced operation could surface in the future. A paper was published in a scientific journal.
