A group of physicists from the University of Jagello in Poland and the Swinburn University in Australia have put forward a novel solution to tackle errors in quantum computers. Krzhishtof Gerzhgel, Krzhishtof Sasha, and Peter Hannaford detailed their innovative idea on the ARXIV preprint server.
Quantum computers hold the promise of revolutionizing computer technology, but they are still in the early stages of development. Despite the potential, no one has managed to create a quantum computer that is truly efficient. The progress in this field is hindered by a number of challenges, with errors during computations being a major issue that scientists are working to address.
The errors in quantum computers occur when the qubits interact during calculations, leading to state degeneration and loss of information. The research group’s new concept aims to enable qubits to function in a way that minimizes degradation during interactions.
Temporal crystals are a unique form of substance structure where atoms are organized not only in space but also in time. These crystals exhibit repetitive structures at specific time intervals, making them well-suited for quantum computations that require both spatial and temporal interactions to be precise.
The team suggests the creation of temporary printed circuit boards using ultra-cold atoms that move in recurring patterns similar to regular crystals, thus forming temporal crystals. This approach will allow the qubits to be distributed throughout the quantum computer and remain in constant motion, enabling them to interact without deterioration.
Furthermore, this design will permit the qubits to be placed far apart from each other, a feat that is currently unachievable with existing structures, thereby paving the way for more intricate calculations. The research group is currently working on implementing this concept by utilizing ultra-cold potassium to develop temporary crystals for the construction of a quantum computer.
