Ionisation of one of a pair of dopant atoms ( 11, 12 ) in a substrate ( 13 ) creates a double well potential, and a charge qubit is realised by the location of one or more electrons or holes ( 14 ) within this potential. The dopant atoms may comprise phosphorous atoms, located in a silicon substrate. A solid state quantum computer may be formed using a plurality of pairs of dopant atoms ( 11, 12 ), corresponding gate electrodes ( 22, 23 ), and read-out devices comprising single electron transistors ( 24 ).
