Quantum searching amidst uncertainty
Lov K. Grover
Consider a database most of whose entries are marked but the precise fraction of marked entries is not known. What is known is that the fraction of marked entries is 1-X, where X i…
Quantum error correction of systematic errors using a quantum search framework
Ben W. Reichardt, Lov K. Grover
Composite pulses are a quantum control technique for canceling out systematic control errors. We present a new composite pulse sequence inspired by quantum search. Our technique ca…
A new algorithm for fixed point quantum search
Tathagat Tulsi, Lov Grover, Apoorva Patel
The standard quantum search lacks a feature, enjoyed by many classical algorithms, of having a fixed point, i.e. monotonic convergence towards the solution. Recently a fixed point…
Simple Algorithm for Partial Quantum Search
Vladimir E. Korepin, Lov K. Grover
Quite often in database search, we only need to extract portion of the information about the satisfying item. Recently Radhakrishnan & Grover [RG] considered this problem in the fo…
Preserving Quantum States : A Super-Zeno Effect
Deepak Dhar, Lov K. Grover, Shasanka M. Roy
We construct an algorithm for suppressing the transitions of a quantum mechanical system, initially prepared in a subspace P of the full Hilbert space of the system, to outside thi…
