Oxford scientists achieve quantum data teleportation milestone
A breakthrough in quantum data teleportation has been achieved. Scientists at the University of Oxford have successfully transmitted data between quantum computers, addressing one of the key challenges posed by the development of this technology. Experts suggest that this milestone could revolutionise the technology sector.
Researchers from the University of Oxford have published their findings in "Nature", detailing the process of transmitting data between two quantum computers using quantum teleportation. Despite the computers being only two yards apart for the experiment, the technique is theorised to work over any distance.
Quantum teleportation will be a breakthrough
This discovery is pivotal because it tackles a significant issue in the realm of quantum computing. According to The Independent, these computers use qubits instead of transistors, allowing for more complex computations. However, the challenge lies in the size of the equipment required for data transmission. For the technology to be integrated into daily life, specialists need to devise a method to miniaturise the necessary components.
Researchers are endeavouring to connect multiple quantum computers to function as a single unit. Similar to traditional distributed processing, where numerous computers collaborate on a singular problem, quantum computers can also be networked.
Quantum entanglement is essential for data transmission
Quantum entanglement is crucial for linking two quantum computers. This requires that quantum objects are placed at both ends of the transmission. Entanglement places both qubits in an unknown yet correlated state. Scientists constructed two ion traps linked by a two-yard optical cable, with each trap containing a strontium and calcium ion. The calcium ion served as local memory, while the strontium acted as a quantum network interface.
The breakthrough occurred after extensive testing with Grover's algorithm. The network yielded correct results approximately 70% of the time. The errors were attributed not to the teleportation process itself, but to local hardware operations. Experts are optimistic that using commercial quantum equipment will enhance the accuracy of the results.
