Researchers in the Laboratory for Solid State Physics at ETH Zurich found evidence that bilayer graphene quantum
dots may host a promising new type of quantum bit based on so-called valley states. In quantum computing, the question as to what physical system, and which degrees
of freedom within that system, may be used to encode quantum bits of information – qubits, in short – is at the heart of many research projects carried out in physics
and engineering laboratories.
