Quantum Proofs for Classical Theorems
... where [n] denotes the set {1, . . . , n} and the vectors |i, ji = |ii ⊗ | ji form an orthonormal basis for Cmn . This tensor product of states |φ i and |ψi is also often denoted simply as |φ i|ψi. Note that this new state is a unit vector, as it should be. Not every pure state in Cmn can be expresse ...

The Need for Structure in Quantum Speedups
... Conjecture 3 (Watrous 2002) R(f ) ≤ Q(f )O(1) for every partial function f : [M ]N → {0, 1, ∗} that is permutation-invariant. Let us make two remarks about Conjecture 3. First, the conjecture talks about randomized versus quantum query complexity, since in this setting, it is easy to find functions ...
