Replication and Evolution of Quantum Species
Arun K. Pati
We dwell upon the physicist's conception of `life' since Schroedinger and Wigner through to the modern-day language of living systems in the light of quantum information. We discus…
Inconsistencies of the Adiabatic Theorem and the Berry Phase
A. K. Pati, A. K. Rajagopal
The adiabatic theorem states that if we prepare a quantum system in one of the instantaneous eigenstates then the quantum number is an adiabatic invariant and the state at a later…
Exact remote state preparation for multiparties
P. Agrawal, P. Parashar, A. K. Pati
We discuss the exact remote state preparation protocol of special ensembles of qubits at multiple locations. We also present generalization of this protocol for higher dimensional…
Quantum mechanical Universal constructor
Arun K. Pati, Samuel L. Braunstein
Arbitrary quantum states cannot be copied. In fact, to make a copy we must provide complete information about the system. However, can a quantum system self-replicate? This is not…
Relative phase change during quantum operation
Arun K. Pati
Quantum operations represented by completely positive maps encompass many of the physical processes and have been very powerful in describing quantum computation and information pr…
Remote state preparation and measurement of single photon
Arun K. Pati
Quantum information theory has revolutionized the way in which information is processed using quantum resources such as entangled states, local operations and classical communicati…
