Induced Ginibre ensemble of random matrices and quantum operations
Induced Ginibre ensemble random matrices quantum operations
2011/9/20
Abstract: A generalisation of the Ginibre ensemble of non-Hermitian random square matrices is introduced. The corresponding probability measure is induced by the ensemble of rectangular Gaussian matri...
Overview of the Tevatron Collider Complex: Goals, Operations and Performance
Accelerator Subsystems and Technologies Instrumentation for particle accelerators and storage rings - high energy (linear accelerators, synchrotrons)
2011/8/29
ABSTRACT: For more than two decades the Tevatron proton-antiproton collider was the centerpiece of the world’s high energy physics program. The collider was arguably one of the most complex research i...
Optimal Perfect Distinguishability between Unitaries and Quantum Operations
Optimal Perfect Distinguishability Unitaries Quantum Operations
2010/11/4
We study optimal perfect distinguishability between a unitary and a general quantum operation. In 2-dimensional case we provide a simple sufficient and necessary condition for sequential perfect disti...
Comparing globalness of bipartite unitary operations acting on quantum information: delocalization power, entanglement cost, and entangling power
Comparing globalness bipartite unitary operations acting quantum information delocalization power entanglement cost entangling power
2010/11/8
We compare three different characterizations of the globalness of bipartite unitary operations based on different tasks, namely, delocalization power, entanglement cost for LOCC implementation, and e...
Continuous Quantum Error Correction Through Local Operations
Continuous Quantum Error Correction Through Local Operations
2010/10/21
We propose local strategies to protect global quantum information. The protocols, which are
quantum error correcting codes for dissipative systems, are based on environment measurements,
direct feed...
This thesis is divided into two parts. In Part I we introduce a new formalism for quantum strategies, which specify the actions of one party in any multi-party interaction involving the exchange of mu...
Continuity properties of the output entropy of positive linear maps between Banach spaces of trace class operators are investigated with the special attention to the classes of quantum channels and op...

2010/4/1
A method is presented for realizing logic operations in a micromechanical cantilever array based on the timed application of a lattice disturbance to control the properties of intrinsic localized mode...

2009/11/24
Physicists in the US have used two trapped atomic ions to create the first multiple-qubit programmable quantum computer. The device can be controlled to perform at least 160 different quantum computin...
Global operations for protected quantum memories in atomic spin lattices
Global operations quantum memories atomic spin lattices
2010/4/9
Quantum information processed in strongly correlated states of matter can provide built in hardware protection against errors. We may encode information in highly non local degrees of freedom, such as...
