Quantum information processing has great advantages in information processing and computation. The design of a programmable quantum computation apparatus is an important step toward building a general purpose quantum computer (QC). We review recent progress in this field, including the impossibility of building an arbitrarily programmable QC, as well as the design of QCs with probabilistic and precise programming, determinate and approximate programming, and a quantum measuring apparatus controlled by software. Finally, a simple introduction to thephysical realization of QCs and future prospects is presented.
