Effects of realistic pulse shapes in two-dimensional spectroscopy
M. Russo, R. Gilliot, A. Blech +3
Two-dimensional (2D) spectroscopy is a powerful pump-pump-probe technique for revealing couplings between quantum states and disentangling the different contributions to the optica…
Collective states of multi-level emitters: The role of multi-level interferences
Nathan E. Rahat, Christiane P. Koch
We explore how collective states of light and matter differ when the multi-level nature of the quantum emitters is fully taken into account. For closely spaced emitters, interferen…
Determining the ability for universal quantum computing: Testing controllability via dimensional expressivity
Fernando Gago-Encinas, Tobias Hartung, Daniel M. Reich +2
Operator controllability refers to the ability to implement an arbitrary unitary in SU(N) and is a prerequisite for universal quantum computing. Controllability tests can be used i…
Graph test of controllability in qubit arrays: A systematic way to determine the minimum number of external controls
Fernando Gago-Encinas, Monika Leibscher, Christiane P. Koch
The ability to implement any desired quantum logic gate on a quantum processing unit is equivalent to evolution-operator controllability of the qubits. Conversely, controllability…
Tomography of Feshbach Resonance States
Baruch Margulis, Karl P. Horn, Daniel M. Reich +8
Feshbach resonances are fundamental to interparticle interactions and become particularly important in cold collisions with atoms, ions, and molecules. Here we present the detectio…
Optimizing for an arbitrary Schrödinger cat state. II. Application in the presence of dissipation
Matthias G. Krauss, Daniel M. Reich, Christiane P. Koch
We extend here the optimization functional targeting arbitrary cat states, derived in the companion paper, to open quantum system dynamics. Applying it to a Jaynes-Cummings model w…
