Recently, span programs have been shown to be equivalent to quantum query algorithms. It is an open problem whether this equivalence can be utilized in order to come up with new quantum algorithms. We address this problem by providing span programs for some linear algebra problems. We develop a notion of a high level span program, that abstracts from loading input vectors into a span program. Then we give a high level span program for the rank problem. The last section of the paper deals with…

Span Programs are Equivalent to Quantum Query Algorithms

TLDR
It is proved that for any boolean function, the optimal “witness size” of a span program equals the general adversary bound, therefore, span program witness size and quantum query complexity are equivalent measures.
