Exactly solvable two-level quantum systems and Landau-Zener interferometry
Edwin Barnes
I present a simple algorithm based on a type of partial reverse-engineering that generates an unlimited number of exact analytical solutions to the Schrodinger equation for a gener…
Analytically solvable driven time-dependent two-level quantum systems
Edwin Barnes, S. Das Sarma
Analytical solutions to the time-dependent Schrodinger equation describing a driven two-level system are invaluable to many areas of physics, but they are also extremely rare. Here…
Nonperturbative master equation solution of central spin dephasing dynamics
Edwin Barnes, Łukasz Cywiński, S. Das Sarma
We solve the long-standing central spin problem for a general set of inhomogeneous bath couplings and a large class of initial bath states. We compute the time evolution of the coh…
Composite pulses for robust universal control of singlet-triplet qubits
Xin Wang, Lev S. Bishop, J. P. Kestner +3
Precise qubit manipulation is fundamental to quantum computing, yet experimental systems generally have stray coupling between the qubit and the environment, which hinders the nece…
