Experimental Realization of Asymmetric Phase-Covariant Quantum Cloning
Hongwei Chen, Xianyi Zhou, Dieter Suter +1
While exact cloning of an unknown quantum state is prohibited by the linearity of quantum mechanics, approximate cloning is possible and has been used, e.g., to derive limits on th…
Quantum information processing using strongly-dipolar coupled nuclear spins
T. S. Mahesh, Dieter Suter
Dipolar coupled homonuclear spins present challenging, yet useful systems for quantum information processing. In such systems, eigenbasis of the system Hamiltonian is the appropria…
Deformed Geometric Algebra and Supersymmetric Quantum Mechanics
Peter Henselder
Deforming the algebraic structure of geometric algebra on the phase space with a Moyal product leads naturally to supersymmetric quantum mechanics in the star product formalism.
Keeping a Quantum Bit Alive by Optimized -Pulse Sequences
Götz S. Uhrig
A general strategy to maintain the coherence of a quantum bit is proposed. The analytical result is derived rigorously including all memory and back-action effects. It is based on…
