Spectrum of coherently backscattered light from two atoms
Vyacheslav Shatokhin, Thomas Wellens, Benoît Grémaud +1
We present a detailed analytical and numerical analysis of the inelastic coherent backscattering spectrum of laser light incident on cold atoms. We identify frequency domains where…
Inflationary dynamics for matrix eigenvalue problems
Eric J. Heller, Lev Kaplan, Frank Pollmann
Many fields of science and engineering require finding eigenvalues and eigenvectors of large matrices. The solutions can represent oscillatory modes of a bridge, a violin, the disp…
Quantum Computational Method of Finding the Ground State Energy and Expectation Values
Sangchul Oh
We propose a new quantum computational way of obtaining a ground-state energy and expectation values of observables of interacting Hamiltonians. It is based on the combination of t…
Femtosecond Photodissociation of Molecules Facilitated by Noise
Kamal P. Singh, Anatole Kenfack, Jan M. Rost
We investigate the dynamics of diatomic molecules subjected to both a femtosecond mid-infrared laser pulse and Gaussian white noise. The stochastic Schrödinger equation with a Mors…
Coherent backscattering of light from saturated atoms
Vyacheslav Shatokhin, Thomas Wellens, Cord Müller +1
We survey recent progress achieved in understanding the impact of inelastic processes on coherent backscattering of light from cold atoms that are saturated by a powerful laser fie…
Scalable experimental estimation of multipartite entanglement
Leandro Aolita, Andreas Buchleitner, Florian Mintert
We present an efficient experimental estimation of the multipartite entanglement of mixed quantum states in terms of simple parity measurements.
Dissociation and ionization of small molecules steered by external noise
Anatole Kenfack, Jan M. Rost, Frank Grossmann
We show that ionization and dissociation can be influenced separately in a molecule with appropriate external noise. Specifically we investigate the hydrogen molecular ion under a…
Resonant ratcheting of a Bose-Einstein condensate
Luis Morales-Molina, Sergej Flach
We study the rectification process of interacting quantum particles in a periodic potential exposed to the action of an external ac driving. The breaking of spatio-temporal symmetr…
Entanglement Witnesses from Single-Particle Interference
T. Scholak, F. Mintert, C. A. Müller
We describe a general method of realizing entanglement witnesses in terms of the interference pattern of a single quantum probe. After outlining the principle, we discuss specific…
A Factorization Law for Entanglement Decay
Thomas Konrad, Fernando de Melo, Markus Tiersch +3
We present a simple and general factorization law for quantum systems shared by two parties, which describes the time evolution of entanglement upon passage of either component thr…
Femtosecond Photoionization of Atoms under Noise
Kamal P. Singh, Jan M. Rost
We investigate the effect of incoherent perturbations on atomic photoionization due to a femtosecond mid-infrared laser pulse by solving the time-dependent stochastic Schrödinger e…
The brachistochrone problem in open quantum systems
Ingrid Rotter
Recently, the quantum brachistochrone problem is discussed in the literature by using non-Hermitian Hamilton operators of different type. Here, it is demonstrated that the passage…
Controlling the Ratchet Effect for Cold Atoms
Anatole Kenfack, Jiangbin Gong, Arjendu K. Pattanayak
Low-order quantum resonances manifested by directed currents have been realized with cold atoms. Here we show that by increasing the strength of an experimentally achievable delta-…
Extreme statistics of complex random and quantum chaotic states
Arul Lakshminarayan, Steven Tomsovic, Oriol Bohigas +1
An exact analytical description of extreme intensity statistics in complex random states is derived. These states have the statistical properties of the Gaussian and Circular Unita…
The modular multiplication operator and the quantized bakers maps
Arul Lakshminarayan
The modular multiplication operator, a central subroutine in Shor's factoring algorithm, is shown to be a coherent superposition of two quantum bakers maps when the multiplier is 2…
High-fidelity ion-trap quantum computing with hyperfine clock states
L. Aolita, K. Kim, J. Benhelm +2
We propose the implementation of a geometric-phase gate on magnetic-field-insensitive qubits with -dependent forces for trapped ion quantum computing. The force is exerted…
Universal quantum computation in decoherence-free subspaces with hot trapped-ions
Leandro Aolita, Luiz Davidovich, Kihwan Kim +1
We consider interactions that generate a universal set of quantum gates on logical qubits encoded in a collective-dephasing-free subspace, and discuss their implementations with tr…
Periodically driven Quantum Ratchets: Symmetries and Resonances
S. Denisov, L. Morales-Molina, S. Flach +1
We study the quantum version of a tilting and flashing Hamiltonian ratchets, consisting of a periodic potential and a time-periodic driving field. The system dynamics is governed b…
Entanglement-screening by nonlinear resonances
Ignacio Garcia-Mata, Andre R. R. Carvalho, Florian Mintert +1
We show that nonlinear resonances in a classically mixed phase space allow to define generic, strongly entangled multi-partite quantum states. The robustness of their multipartite…
