High Order Coherent Control Sequences of Finite-Width Pulses
S. Pasini, P. Karbach, G. S. Uhrig
The performance of sequences of designed pulses of finite length is analyzed for a bath of spins and it is compared with that of sequences of ideal, instantaneous pulses. The d…
Optimized pulses for the perturbative decoupling of spin and decoherence bath
S. Pasini, P. Karbach, C. Raas +1
In the framework of nuclear magnetic resonance, we consider the general problem of the coherent control of a spin coupled to a bath by means of composite or continuous pulses of du…
Numerical Analysis of Optimized Coherent Control Pulses
P. Karbach, S. Pasini, G. S. Uhrig
Numerically we simulate the effect of optimized coherent control pulses with a finite duration on a qubit in a bath of spins. The pulses of finite duration are compared with ideal…
Optimization of Short Coherent Control Pulses
S. Pasini, T. Fischer, P. Karbach +1
The coherent control of small quantum system is considered. For a two-level system coupled to an arbitrary bath we consider a pulse of finite duration. We derive the leading and th…
Spin Chains as Perfect Quantum State Mirrors
Peter Karbach, Joachim Stolze
Quantum information transfer is an important part of quantum information processing. Several proposals for quantum information transfer along linear arrays of nearest-neighbor coup…
