TLDR
Experimental realization shows that the structural resolution of today's pulse shapers is easily sufficient for pulse formation and the scaling of the system is favorable; sources for decoherence can be eliminated.Abstract:
A new physical implementation for quantum computation is proposed. The vibrational modes of molecules are used to encode qubit systems. Global quantum logic gates are realized using shaped femtosecond laser pulses which are calculated applying optimal control theory. The scaling of the system is favorable; sources for decoherence can be eliminated. A complete set of one- and two-quantum gates is presented for a specific molecule. Detailed analysis regarding experimental realization shows that the structural resolution of today's pulse shapers is easily sufficient for pulse formation.read more

NMR techniques for quantum control and computation
TL;DR: In this article, a broad variety of pulse control and tomographic techniques have been developed for, and used in, NMR quantum computation and many of these will be useful in other quantum systems now being considered for the implementation of quantum information processing tasks.

Quantum control of molecular rotation
TL;DR: The angular momentum of molecules is naturally quantized, time evolution is governed by a well-known Hamiltonian with only a few accurately known parameters, and transitions between rotational levels can be driven by external fields from various parts of the electromagnetic spectrum.

A geometric approach to quantum circuit lower bounds
TL;DR: In this article, a lower bound on the minimal size of a quantum unitary operation is provided by the length of the minimal geodesic between U and the identity, where length is defined by a suitable Finsler metric on SU(2^n).

Dynamics and manipulation of entanglement in coupled harmonic systems with many degrees of freedom
TL;DR: In this paper, the authors studied the entanglement dynamics of a system consisting of a large number of coupled harmonic oscillators in various configurations and for different types of nearest-neighbour interactions.
