Uhlmann’s parallelism in quantum estimation theory

نویسنده

  • Keiji Matsumoto
چکیده

Two important classes of the quantum statistical model, the locally quasi-classical model and the quasi-classical model, are introduced from the estimation theoretical viewpoint, and they are characterized geometrically by the vanishing conditions of the relative phase factor (RPF), implying the close tie between Uhlmann parallel transport and the quantum estimation theory.

Off-diagonal quantum holonomy along density operators

Uhlmann’s concept of quantum holonomy for paths of density operators is generalised to the off-diagonal case providing insight into the geometry of state space when the Uhlmann holonomy is undefined. Comparison with previous off-diagonal geometric phase definitions is carried out and an example comprising the transport of a Bell-state mixture is given.

Quantum parallelism in quantum information processing

We investigate distinguishability (measured by the fidelity) of the initial and the final state of a qubit, which is an object of the so-called nonideal quantum measurement of the first kind. We show that the fidelity of a nonideal measurement can be greater than the fidelity of the corresponding ideal measurement. This result is somewhat counterintuitive, and can be traced back to the quantum ...

Some properties of partial fidelities

Basic properties of Uhlmann’s partial fidelities are discussed. Statistical interpretation in terms of POVM measurements is established. Multiplicativity properties are considered. The relationship between partial fidelities and partitioned trace distances is derived. As it is shown, the partial fidelities cannot decrease under unistochastic quantum operations. Thus, the partial fidelities have...

Technical Report No. 2005-495 ON THE IMPORTANCE OF PARALLELISM FOR QUANTUM COMPUTATION AND THE CONCEPT OF A UNIVERSAL COMPUTER

The role played by parallelism in the theory of computation depends on the particular paradigm or computational environment considered, but its importance has been con rmed with the emergence of each novel computing technology. In this paper we study the implications of parallelism in quantum information theory and show that a parallel approach can make the di erence between success and failure...

On geometric phases for quantum trajectories

A sequence of completely positive maps can be decomposed into quantum trajectories. The geometric phase or holonomy of such a trajectory is delineated. For nonpure initial states, it is shown that well-defined holonomies can be assigned by using Uhlmann’s concept of parallel transport along the individual trajectories. We put forward an experimental realization of the geometric phase for a quan...
