Chip-to-chip entanglement of transmon qubits using engineered measurement fields
C. Dickel, J. J. Wesdorp, N. K. Langford +6
While the on-chip processing power in circuit QED devices is growing rapidly, an open challenge is to establish high-fidelity quantum links between qubits on different chips. Here,…
Local Hamiltonians for one-dimensional critical models
Dillip K. Nandy, N. S. Srivatsa, Anne E. B. Nielsen
Conformal field theory has turned out to be a powerful tool to derive interesting lattice models with analytical ground states. Here, we investigate a class of critical, one-dimens…
Direct frequency-comb-driven Raman transitions in the terahertz range
Cyrille Solaro, Steffen Meyer, Karin Fisher +2
We demonstrate the use of a femtosecond frequency comb to coherently drive stimulated Raman transitions between terahertz-spaced atomic energy levels. More specifically, we address…
Probing the temperature of cold many-body quantum systems
Karen V. Hovhannisyan, Luis A. Correa
It is "conventional wisdom" that the uncertainty of local temperature measurements on equilibrium systems diverges exponentially fast as their temperature drops to zero. In con…
Fast state transfer in a Λ-system: a shortcut-to-adiabaticity approach to robust and resource optimized control
Henrik Lund Mortensen, Jens Jakob W. H. Sørensen, Klaus Mølmer +1
We propose an efficient strategy to find optimal control functions for state-to-state quantum control problems. Our procedure first chooses an input state trajectory, that can real…
Effective second-order correlation function and single-photon detection
Peter Grünwald
Quantum-optical research on semiconductor single-photon sources puts special emphasis on the measurement of the second-order correlation function , arguing that $g^{(2)…
Towards macroscopic spin and mechanical superposition via Rydberg interaction
Mohammadsadegh Khazali
This paper is a proposal for the generation of many-body entangled state in atomic and mechanical systems. Application of strong Rydberg dressing interaction and fast bifurcation s…
Prediction and retrodiction with continuously monitored Gaussian states
Jinglei Zhang, Klaus Mølmer
Gaussian states of quantum oscillators are fully characterized by the mean values and the covariance matrix of their quadrature observables. We consider the dynamics of a system of…
Photon Subtraction by Many-Body Decoherence
Callum R. Murray, Ivan Mirgorodskiy, Christoph Tresp +5
We experimentally and theoretically investigate the scattering of a photonic quantum field from another stored in a strongly interacting atomic Rydberg ensemble. Considering the ma…
Controllability in tunable chains of coupled harmonic oscillators
L. F. Buchmann, K. Mølmer, D. Petrosyan
We prove that temporal control of the strengths of springs connecting harmonic oscillators in a chain provides complete access to all Gaussian states of collective modes.…
Inductive-detection electron-spin resonance spectroscopy with spins sensitivity
S. Probst, A. Bienfait, P. Campagne-Ibarcq +10
We report electron spin resonance spectroscopy measurements performed at millikelvin temperatures in a custom-built spectrometer comprising a superconducting micro-resonator at …
Conditioned spin and charge dynamics of a single electron quantum dot
Eliska Greplova, Edward A. Laird, G. Andrew D. Briggs +1
In this article we describe the incoherent and coherent spin and charge dynamics of a single electron quantum dot. We use a stochastic master equation to model the state of the sys…
A quantum Otto engine with finite heat baths: energy, correlations, and degradation
Alejandro Pozas-Kerstjens, Eric G. Brown, Karen V. Hovhannisyan
We study a driven harmonic oscillator operating an Otto cycle between two thermal baths of finite size. By making extensive use of the tools of Gaussian quantum mechanics, we direc…
High-fidelity Rydberg quantum gate via a two-atom dark state
David Petrosyan, Felix Motzoi, Mark Saffman +1
We propose a two-qubit gate for neutral atoms in which one of the logical state components adiabatically follows a two-atom dark state formed by the laser coupling to a Rydberg sta…
Relaxation of an ensemble of two-level emitters in a squeezed bath
Alexander Holm Kiilerich, Klaus Mølmer
We derive and evaluate equations of motion for the mean values and variances of the components of spins collectively coupled to a broadband squeezed radiation reservoir. Our formal…
Sequentially generated entanglement, macroscopicity and squeezing in a spin chain
Tahereh Abad, Klaus Mølmer, Vahid Karimipour
We study quantum states generated by a sequence of nearest neighbor bipartite entangling operations along a one-dimensional chain of spin qubits. After a single sweep of such a set…
Transient dynamics in cavity electromagnetically induced transparency with ion Coulomb crystals
Magnus Albert, Aurélien Dantan, Michael Drewsen
We experimentally investigate the transient dynamics of an optical cavity field interacting with large ion Coulomb crystals in a situation of electromagnetically induced transparen…
Window for Efimov physics for few-body systems with finite-range interactions
S. E. Rasmussen, A. S. Jensen, D. V. Fedorov
We investigate the two lowest-lying weakly bound states of bosons as functions of the strength of two-body Gaussian interactions. We observe the limit for validity of Ef…
The Goldilocks model of separable, zero-range, few-body interactions in one-dimensional harmonic traps
Molte Emil Strange Andersen, N. L. Harshman, Nikolaj Thomas Zinner
This article introduces the "Goldilocks model" for a few repulsively interacting particles trapped in a one-dimensional harmonic well and provides exact solutions for the three-par…

Tarek A. Elsayed, Klaus Mølmer, Lars Bojer Madsen
Bohmian mechanics is an interpretation of quantum mechanics that describes the motion of quantum particles with an ensemble of deterministic trajectories. Several attempts have bee…
