Symmetric graphene quantum dots for future qubits

Quantum dots in semiconductors akin to silicon or gallium arsenide have lengthy been thought-about sizzling candidates for internet hosting quantum bits in future quantum processors. Scientists have now proven that bilayer graphene has much more to supply right here than different supplies. The double quantum dots they’ve created are characterised by a virtually good electron-hole-symmetry that permits a sturdy read-out mechanism — one of many essential standards for quantum computing.
