Experimental implementation of optimal phase-covariant quantum cloning machine with a single electron spin in diamond at room temperature
Experimental implementation optimal phase-covariant quantum cloning machine single electron spin diamond at room temperature
2010/10/19
Here we report an experimental realization of optimal phase-covariant quantum cloning machine
with a single electron spin in solid state system at room temperature. The involved three states of two l...
Simultaneous time-optimal control of the inversion of two spin 1/2 particles
Simultaneous time-optimal control inversion two spin 1/2 particles
2010/10/18
We analyze the simultaneous time-optimal control of two-spin systems.The two non coupled spins which differ in the value of their chemical off-sets are controlled by the same magnetic fields. Using an...

The optimal unitary dilation bosonic Gaussian channels
2010/10/18
A generic quantum channel can be represented in terms of a unitary interaction between the informationcarrying system and a noisy environment. Here, the minimal number of quantum Gaussian environmenta...

Optimal quantum cloning is the process of making one or more copies of an arbitrary unknown
input quantum state with the highest possible fidelity. All reported demonstrations of quantum
cloning hav...
