Grover search algorithm with Rydberg-blockaded atoms: Quantum Monte Carlo simulations
David Petrosyan, Mark Saffman, Klaus Mølmer
We consider the Grover search algorithm implementation for a quantum register of size using k (or k +1) microwave- and laser-driven Rydberg-blockaded atoms, following the…
An interpolatory ansatz captures the physics of one-dimensional confined Fermi systems
M. E. S. Andersen, A. S. Dehkharghani, A. G. Volosniev +2
Interacting one-dimensional quantum systems play a pivotal role in physics. Exact solutions can be obtained for the homogeneous case using the Bethe ansatz and bosonisation techniq…
Conditioned quantum motion of an atom in a continuously monitored 1D lattice
Ralf Blattmann, Klaus Mølmer
We consider a quantum particle on a one dimensional lattice subject to weak local measurements and study its stochastic dynamics conditioned on the measurement outcomes. Depending…
Tunable self-assembled spin chains of strongly interacting cold atoms
N. J. S. Loft, O. V. Marchukov, D. Petrosyan +1
We have developed an efficient computational method to treat long, one-dimensional systems of strongly-interacting atoms forming self-assembled spin chains. Such systems can be use…
Exterior time scaling with stiffness-free Lanczos time propagator: formulation and application to atoms interacting with strong mid-infrared lasers
Haruhide Miyagi, Lars Bojer Madsen
Aiming at efficient numerical treatment of tunneling ionization of atoms and molecules by mid-infrared (IR) lasers, exterior time scaling (ETS) theory is formulated as a generaliza…
Entanglement of an Impurity in a Few-Body One-Dimensional Ideal Bose System
M. A. García-March, A. S. Dehkharghani, N. T. Zinner
We study the correlation between an impurity and a small ensemble of bosonic particles in one dimension. Our study analyzes the one-body density matrix and calculates the correspon…
Satisfying the Einstein-Podolsky-Rosen criterion with massive particles
J. Peise, I. Kruse, K. Lange +8
In 1935, Einstein, Podolsky and Rosen (EPR) questioned the completeness of quantum mechanics by devising a quantum state of two massive particles with maximally correlated space an…
Manipulation of collective quantum states in Bose-Einstein condensates by continuous imaging
Andrew C. J. Wade, Jacob F. Sherson, Klaus Mølmer
We develop a Gaussian state treatment that allows a transparent quantum description of the continuous, nondestructive imaging of and feedback on a Bose-Einstein condensate. We have…
Interaction-free measurements by quantum Zeno stabilisation of ultracold atoms
J. Peise, B. Lücke, L. Pezzè +6
Quantum mechanics predicts that our physical reality is influenced by events that can potentially happen but factually do not occur. Interaction-free measurements (IFMs) exploit th…
On the adiabatic preparation of spatially-ordered Rydberg excitations of atoms in a one-dimensional optical lattice by laser frequency sweeps
David Petrosyan, Klaus Mølmer, Michael Fleischhauer
We examine the adiabatic preparation of crystalline phases of Rydberg excitations in a one-dimensional lattice gas by frequency sweep of the excitation laser, as proposed by Pohl e…

Christian Kraglund Andersen, Joseph Kerckhoff, Konrad W. Lehnert +2
We propose to use a cryogenic nonlinear resonator for the projective readout, classical memory, and feedback for a superconducting qubit. This approach sidesteps many of the ineffi…
Correlations of the time dependent signal and the state of a continuously monitored quantum system
N. Foroozani, M. Naghiloo, D. Tan +2
In quantum physics, measurements give random results and yield a corresponding random back action on the state of the system subject to measurement. If a quantum system is probed c…
