Topological quantum computer
Moiré materials are made by stacking single-atom-thickness sheets (like graphene) with a slight twist or mismatch between the layers. This slight misalignment creates larger, over-arching patterns known as moiré patterns.
Under certain conditions, moiré materials can exhibit what is known as topological quantum states. These quantum states form uniquely as a result of electron interactions. They are of interest because they could be used to build quantum computers.
Topological quantum computing stands apart from current approaches by following a fundamentally different strategy. Instead of encoding information in fragile qubits, topological quantum computers would use the global properties of exotic quantum states, making them inherently more stable and less error-prone.
