Time-dependent restricted-active-space self-consistent-field theory for bosonic many-body systems
Camille Lévêque, Lars Bojer Madsen
We describe the time-dependent restricted-active-space self-consistent-field (TD-RASSCF) method for a system of interacting bosons. We provide the theory of the method and discuss…
A Mathematical Analysis of Dressed Photon in Ground State of Generalized Quantum Rabi Model Using Pair Theory
Masao Hirokawa, Jacob Schach Moller, Itaru Sasaki
We consider the generalized quantum Rabi model with the so-called -term in the light of the Hepp-Lieb-Preparata quantum phase transition. We investigate the dressed photon i…
Creation and transfer of non-classical states of motion using Rydberg dressing of atoms in a lattice
L F Buchmann, K Mølmer, D Petrosyan
We theoretically investigate the manipulation of the motional states of trapped ground-state atoms using Rydberg dressing via nonresonant laser fields. The forces resulting from Ry…
Low-temperature thermometry can be enhanced by strong coupling
Luis A. Correa, Martí Perarnau-Llobet, Karen V. Hovhannisyan +3
We consider the problem of estimating the temperature of a very cold equilibrium sample. The temperature estimates are drawn from measurements performed on a quantum probe st…
Quantum spin transistor with a Heisenberg spin chain
O. V. Marchukov, A. G. Volosniev, M. Valiente +2
We propose and analyze a scheme for conditional state transfer in a Heisenberg spin chain which realizes a quantum spin transistor. In our scheme, the absence or presence of…
Random search for a dark resonance
Alexander Holm Kiilerich, Klaus Mølmer
A pair of resonant laser fields can drive a three-level system into a dark state where it seizes to absorb and emit radiation due to destructive interference. We propose a scheme t…
Distinguishability and many-particle interference
Adrian J. Menssen, Alex E. Jones, Benjamin J. Metcalf +4
Quantum interference of two independent particles in pure quantum states is fully described by the particles' distinguishability: the closer the particles are to being identical, t…
Quantum annealing with a network of all-to-all connected, two-photon driven Kerr nonlinear oscillators
Shruti Puri, Christian Kraglund Andersen, Arne L. Grimsmo +1
Quantum annealing aims to solve combinatorial optimization problems mapped on to Ising interactions between quantum spins. A critical factor that limits the success of a quantum an…
Statistical signatures of states orthogonal to the Fock-state ladder of composite bosons
P. Alexander Bouvrie, Malte C. Tichy, Klaus Mølmer
The theory of composite bosons (cobosons) made of two fermions [Phys. Rev. A 71, 034306 (2005), Phys. Rev. Lett. 109, 260403 (2012)] converges to ordinary structureless bosons in t…
Resonator reset in circuit QED by optimal control for large open quantum systems
Samuel Boutin, Christian Kraglund Andersen, Jayameenakshi Venkatraman +2
We study an implementation of the open GRAPE (Gradient Ascent Pulse Engineering) algorithm well suited for large open quantum systems. While typical implementations of optimal cont…
Proposal for detection of a single electron spin in a microwave resonator
P. Haikka, Y. Kubo, A. Bienfait +2
We propose a method for detecting the presence of a single spin in a crystal by coupling it to a high-quality factor superconducting planar resonator. By confining the microwave fi…
Quantum smoothing for classical mixtures
D. Tan, M. Naghiloo, K. Mølmer +1
In quantum mechanics, wave functions and density matrices represent our knowledge about a quantum system and give probabilities for the outcomes of measurements. If the combined dy…
Hong-Ou-Mandel Interference between Two Deterministic Collective Excitations in an Atomic Ensemble
Jun Li, Ming-Ti Zhou, Bo Jing +6
We demonstrate deterministic generation of two distinct collective excitations in one atomic ensemble, and we realize the Hong-Ou-Mandel interference between them. Using Rydberg bl…

Bhagya Nair, André Xuereb, Aurélien Dantan
Optomechanical arrays made of structured flexible dielectrics are a promising system for exploring quantum and many-body optomechanical phenomena. We generalize investigations of t…
Quantum teleportation with continuous measurements
Eliska Greplova, Klaus Mølmer, Christian Kraglund Andersen
We propose a scheme for quantum teleportation between two qubits, coupled sequentially to a cavity field. An implementation of the scheme is analyzed with superconducting qubits an…
Semi-classical Dynamics of Superradiant Rayleigh Scattering in a Bose-Einstein Condensate
J. H. Müller, D. Witthaut, R. le Targat +3
Due to its coherence properties and high optical depth, a Bose-Einstein condensate provides an ideal setting to investigate collective atom-light interactions. Superradiant light s…
Normal modes of a superconducting transmission-line resonator with embedded lumped element circuit components
Henrik Lund Mortensen, Klaus Mølmer, Christian Kraglund Andersen
We present a method to identify the coupled, normal modes of a superconducting transmission-line with an embedded lumped element circuit. We evaluate the effective transmission-lin…
Ultrastrong coupling dynamics with a transmon qubit
Christian Kraglund Andersen, Alexandre Blais
The interaction of light and matter is often described by the exchange of single excitations. When the coupling strength is a significant fraction of the system frequencies, the nu…

0.75 atoms improve the clock signal of 10,000 atoms
I. Kruse, K. Lange, J. Peise +8
Since the pioneering work of Ramsey, atom interferometers are employed for precision metrology, in particular to measure time and to realize the second. In a classical interferomet…
Single-atom single-photon coupling facilitated by atomic-ensemble dark-state mechanisms
Andrew C. J. Wade, Marco Mattioli, Klaus Molmer
We propose to couple single atomic qubits to photons incident on a cavity containing an atomic ensemble of a different species that mediates the coupling via Rydberg interactions.…
