On divergence, relative entropy and the substate property
Rahul Jain, Jaikumar Radhakrishnan, Pranab Sen
In this article we study relationship between three measures of distinguishability of quantum states called as divergence, relative entropy and the substate property.
Quantum search for multiple items using parallel queries
Lov K. Grover, Jaikumar Radhakrishnan
In the quantum database search problem we are required to search for an item in a database. In this paper, we consider a generalization of this problem, where we are provided d ide…
Is partial quantum search of a database any easier?
Lov K. Grover, Jaikumar Radhakrishnan
In this paper, we consider the partial database search problem where given a database on N items, we are required to determine the first k bits of an address x such that f(x)=1. We…
A lower bound for bounded round quantum communication complexity of set disjointness
Rahul Jain, Jaikumar Radhakrishnan, Pranab Sen
We consider the class of functions whose value depends only on the intersection of the input X_1,X_2, ..., X_t; that is, for each F in this class there is an f_F: 2^{[n]} \to {0,1}…
The Quantum Complexity of Set Membership
Jaikumar Radhakrishnan, Pranab Sen, S. Venkatesh
We study the quantum complexity of the static set membership problem: given a subset S (|S| \leq n) of a universe of size m (m \gg n), store it as a table of bits so that queries o…
