The carbon-based nanomaterials of fullerenes, nanotubes and graphene have excellent properties for hosting arrays of electron-based qubits. Electrons for quantum computing may also be held in a low-decoherence environment on the surface of liquid helium, or be contained in molecular magnets. Schematic diagram of a graphene double quantum dot. Each dot is assumed to have length L and width W. The structure is based on a ribbon of graphene (grey) with semiconducting armchair edges (white).

Graphene for implementing scalable quantum computer

Quantum computing is expected to increase significantly the computational speed since it operates on completely different principles in comparison to classical computers. In addition, it was predicted that quantum computers can increase the computational speed of at least some problems. For instance, a sub-exponential speed-up is expected if the quantum Shor algorithm is applied to the problem of finding the prime factors of an integer number, the quantum Grover algorithm quadratically increases the speed of searching for an item in an unordered list, and an exponential speed-up is foreseen for simulating the dynamics of quantum systems by quantum computers.
