Quantum limit of decoherence: Environment induced superselection of energy eigenstates
Juan Pablo Paz, Wojciech Hubert Zurek
We investigate decoherence in the limit where the interaction with the environment is weak and the evolution is dominated by the self Hamiltonian of the system. We show that in thi…
Complete quantum teleportation using nuclear magnetic resonance
M. A. Nielsen, E. Knill, R. Laflamme
Quantum mechanics provides spectacular new information processing abilities (Bennett 1995, Preskill 1998). One of the most unexpected is a procedure called quantum teleportation (B…
An Introduction to Quantum Computers
Christof Zalka
This is a short introduction to quantum computers, quantum algorithms and quantum error correcting codes. Familiarity with the principles of quantum theory is assumed. Emphasis is…
Time-dependent Schrödinger equations having isomorphic symmetry algebras. II. Symmetry algebras, coherent and squeezed states
Michael Martin Nieto, D. Rodney Truax
Using the transformations from paper I, we show that the Schrödinger equations for: (1)systems described by quadratic Hamiltonians, (2) systems with time-varying mass, and (3) time…
Time-dependent Schrödinger equations having isomorphic symmetry algebras. I. Classes of interrelated equations
Michael Martin Nieto, D. Rodney Truax
In this paper, we focus on a general class of Schrödinger equations that are time-dependent and quadratic in X and P. We transform Schrödinger equations in this class, via a class…
Ultra-bright source of polarization-entangled photons
Paul G. Kwiat, Edo Waks, Andrew G. White +2
Using the process of spontaneous parametric down conversion in a novel two-crystal geometry, one can generate a source of polarization-entangled photon pairs which is orders of mag…
