  Since the 1998 proposal to build a quantum computer using dopants in
semiconductors as qubits, much progress has been achieved on semiconductors
nano fabrication and control of charge and spins in single dopants. However, an
important problem remains, which is the control at the atomic scale of the
dopants positioning. We propose to circumvent this problem by using 2
dimensional materials as hosts. Since the first isolation of graphene in 2004,
the number of new 2D materials with favorable properties for electronics has
been growing. Dopants in 2 dimensional systems are more tightly bound and
potentially easier to position and manipulate. Considering the properties of
currently available 2D materials, we access the feasibility of such proposal in
terms of the manipulability of isolated dopants (for single qubit operations)
and dopant pairs (for two qubit operations). Our results indicate that a wide
variety of 2D materials may perform at least as well as the currently studied
bulk host for donor qubits.
