Iordanis Kerenidis, Ronald de Wolf#### Exponential Lower Bound for 2-Query Locally Decodable Codes

Dmytro Gavinsky, Julia Kempe, Ronald de Wolf

We give an exponential separation between one-way quantum and classical communication complexity for a Boolean function. Earlier such a separation was known only for a relation. A very similar result was obtained earlier but independently by Kerenidis and Raz [KR06]. Our version of the result gives an example in the ... more >>>

A strong direct product theorem says that if we want to compute

k independent instances of a function, using less than k times

the resources needed for one instance, then our overall success

probability will be exponentially small in k.

We establish such theorems for the classical as well as ...

We prove exponential lower bounds on the length of 2-query

locally decodable codes. Goldreich et al. recently proved such bounds

for the special case of linear locally decodable codes.

Our proof shows that a 2-query locally decodable code can be decoded

with only 1 quantum query, and then ...
