Quantum Technology: Scientists Predict Future Of Quantum Systems

Scientists literally predicted the future of the quantum technology. A study in the University of Sydney demonstrated how big data can accurately predict the future of the quantum system. This is a big leap in the practical application of quantum systems as this will enable researchers to do actions that would prevent the quantum system from breaking down.

Quantum-enabled technologies are gaining popularity across the world. However, a challenge on  building reliable quantum technologies is decoherence -- the randomization quantum systems by their environments and effectively destroys quantum character. This makes it disadvantageous in practical applications.  

In a study published in Nature Communications, the researchers used techniques from machine learning and control theory and to predict the future evolution of a qubit's state. They used the superposition in a quantum system where a particle can occupy two different positions at the same time. They then employed predictive feedback during successive but time delayed measurements.

The stability of the qubit-phase demonstrated significant improvements. The researchers added that it was possible to suppress decoherence in the quantum system in a preventive manner. This is applicable to all two-level quantum systems and does not need an additional hardware.

The researchers highlighted that the predictions were very accurate. By anticipating the needed changes in real time, they were able to extend the usefulness of the qubits by preventing the breakdown of the quantum character. These techniques also apply qubits which are built in any technology, including the special superconducting circuits in major corporations.

"We know that building real quantum technologies will require major advances in our ability to control and stabilise qubits -- to make them useful in applications," Professor Biercuk from the University of Sydney's School of Physics said according to Science Daily. "We're excited to be developing new capabilities that turn quantum systems from novelties into useful technologies. The quantum future is looking better all the time," he added.
