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...

28-Mar-2007，CHICAGO, IL -- X-ray studies at the U.S. Department of Energy (DOE) Brookhaven National Laboratory are pointing the way to less costly and more efficient catalysts for improving the perfor...
Search for a Nonelectrocyclic Cyclization of Nitrosostyrene: Rearrangements of Michael Adducts from DMAD and a-Dialkylamino Oximes
Nonelectrocyclic Cyclization of Nitrosostyrene DMAD a-Dialkylamino Oximes
2010/4/21
The aza-Claisen rearrangement product of the Michael adducts 2 from a-dialkylaminoacetophenone oximes and DMAD underwent fragmentation to give dialkylaminomaleate, and benzonitrile at reflux in aceton...
