Grover's quantum search algorithm provides a quadratic advantage over classical algorithms across broad class of unstructured problems. The original protocol is probabilistic, returning the desired result with significant probability on each query but, in general, requiring several iterations algorithm. We present modified version to return correct certainty without having user control oracle. ...

Oracle has been progressively adding support for very large databases and extended objects. The Data Warehouse technique of Oracle may help in storing the Petabyte of data, which will be generated per year by CMS experiment. This report proposes how the Oracle9i tools could be used for event store and client side configuration to access data from Oracle Database by using CMS application.

We study the relative computational power of logspace reduction models. In particular , we study the relationships between one-way and two-way oracle tapes, resetting of the oracle head, and blanking of the oracle tape. We show that oracle models letting information persist between queries can be quite powerful, even if the information is not readable by the querying machine. We show that logsp...

We prove that every key agreement protocol in the random oracle model in which the honest users make at most n queries to the oracle can be broken by an adversary who makes O(n) queries to the oracle. This improves on the previous Ω̃(n) query attack given by Impagliazzo and Rudich (STOC ’89) and resolve an open question posed by them. Our bound is optimal up to a constant factor since Merkle pro...

We saw that using the multiplicative weights (MW) algorithm, we find a (1 + ε)-approximate max flow f̂—i.e., a flow of value F that has f̂e ≤ 1 + ε—using O( logm ε2 ) calls to the oracle. In Lecture #14, we saw that using shortest-path routing, you can get ρ = F . Since we can use Dijkstra’s O(m+ n log n) to implement the oracle, this gives an Õ( ε2 ) time algorithm. Relaxed Oracle: For the rest ...

We study the ability of efficient quantum verifiers to decide properties of exponentially large subsets given either a classical or quantum witness. We develop a general framework that can be used to prove that QCMA machines, with only classical witnesses, cannot verify certain properties of subsets given implicitly via an oracle. We use this framework to prove an oracle separation between QCMA...

We derive oracle inequalities for the problems of isotonic and convex regression using the combination of Q-aggregation procedure and sparsity pattern aggregation. This improves upon the previous results including the oracle inequalities for the constrained least squares estimator. One of the improvements is that our oracle inequalities are sharp, i.e., with leading constant 1. It allows us to ...

Software testing is used to improve software quality by finding fault in the software. To verify the software behavior, testers require test oracle, which is a reliable source of expected software behavior and provides outputs for any input specified in the software specifications and a comparator to verify actual results generated by the software. While test automation requires automated oracl...

The non-committing encryption problem arises in the setting of adaptively secure cryptographic protocols, as the task of implementing secure channels. We prove that in the random oracle model, where the parties have oracle access to a uniformly random function, non-committing encryption can be implemented efficiently using any trapdoor permutation. We also prove that no matter how the oracle is...
