We apply a new formalism to derive the higher-order quantum kinetic expansion (QKE) for studying dissipative dynamics in a general quantum network coupled with an arbitrary thermal bath. The dynamics ...
Quantum Separation of Local Search and Fixed Point Computation
Quantum query complexity Fixed-point computation Local search Sperner’s lemma Quantum adversary method
2012/12/4
We give a lower bound of (n(d−1)/2) on the quantum query complexity for finding a fixed point of a discrete Brouwer function over grid [n]d. Our lower
bound is nearly tight, as Grover Search c...
