"Protecting Quantum Information with Non-Repeating Tiles"
Quantum error-correcting codes, first discovered by Peter Shor in 1995, distribute quantum information across many qubits to prevent errors from derailing computations. These codes can absorb errors and reverse them using established procedures specific to each code. Zhi Li and Latham Boyle discovered a connection between quantum error correction and aperiodic tilings, leading to the possibility of building a quantum error-correcting code based on a class of aperiodic tilings. They started with Penrose tilings and identified tiling configurations that wouldn't be affected by localized errors, similar to virtual qubit states in ordinary quantum error-correcting codes.
