Fast quantum search algorithm and Bounds on it
Arun Kumar Pati
We recast Grover's generalised search algorithm in a geometric language even when the states are not approximately orthogonal. We provide a possible search algorithm based on an ar…
Quantum Zeno Dynamics and Inhibition of Geometric Phase
Arun Kumar Pati, Suresh V. Lawande
If unitary evolution of a quantum system is interrupted by a sequence of measurements we call the dynamics as quantum Zeno dynamics. We show that under quantum Zeno dynamics not on…
Observability of relative phases of macroscopic quantum states
Arun Kumar Pati
After a measurement, to observe the relative phases of macroscopically distinguishable states we have to ``undo'' a quantum measurement. We generalise an earlier model of Peres fro…
Uncertainty, non-locality and Bell's inequality
Arun Kumar Pati
We derive a Bell-like inequality involving all correlations in local observables with uncertainty free states and show that the inequality is violated in quantum mechanics for EPR…
