Microscopic dynamics and an effective Landau-Zener transition in the quasi-adiabatic preparation of spatially ordered states of Rydberg excitations
A. F. Tzortzakakis, D. Petrosyan, M. Fleischhauer +1
We examine the adiabatic preparation of spatially-ordered Rydberg excitations of atoms in finite one-dimensional lattices by frequency-chirped laser pulses, as realized in a number…
Cavity Quantum Electrodynamics Effects with Nitrogen Vacancy Center Spins in Diamond and Microwave Resonators at Room Temperature
Yuan Zhang, Qilong Wu, Shi-Lei Su +3
Cavity quantum electrodynamics (C-QED) effects, such as Rabi splitting, Rabi oscillations and superradiance, have been demonstrated with nitrogen vacancy center spins in diamond in…
Topological phases in interacting spin-1 systems
A. Alnor, T. Bækkegaard, N. T. Zinner
Different topological phases of quantum systems has become areas of increased focus in recent decades. In particular, the question of how to realize and manipulate systems with non…
Free-Fermion Multiply Excited Eigenstates and Their Experimental Signatures in 1D Arrays of Two-Level Atoms
Yu-Xiang Zhang, Klaus Mølmer
One-dimensional (1D) subwavelength atom arrays display multiply excited subradiant eigenstates which are reminiscent of free fermions. So far, these states have been associated wit…
Quantum Wheatstone Bridge
Kasper Poulsen, Alan C. Santos, Nikolaj T. Zinner
We propose a quantum Wheatstone bridge as a fully quantum analogue to the classical version. The bridge is a few-body boundary-driven spin chain exploiting quantum effects to gain…
Quantum Maxwell's Demon Assisted by Non-Markovian Effects
Kasper Poulsen, Marco Majland, Seth Lloyd +2
Maxwell's demon is the quintessential example of information control, which is necessary for designing quantum devices. In thermodynamics, the demon is an intelligent being who uti…
Active Frequency Measurement on Superradiant Strontium Clock Transitions
Yuan Zhang, Chongxin Shan, Klaus Mølmer
We develop a stochastic mean-field theory to describe active frequency measurements of pulsed superradiant emission, studied in recent experiments with strontium-87 atoms trapped i…
Application of the Diamond Gate in Quantum Fourier Transformations and Quantum Machine Learning
E. Bahnsen, S. E. Rasmussen, N. J. S. Loft +1
As we are approaching actual application of quantum technology, it is essential to exploit the current quantum resources in the best possible way. With this in mind, it might not b…
The superconducting circuit companion -- an introduction with worked examples
S. E. Rasmussen, K. S. Christensen, S. P. Pedersen +4
This tutorial aims at giving an introductory treatment of the circuit analysis of superconducting qubits, i.e., two-level systems in superconducting circuits. It also touches upon…
Entanglement-enhanced quantum rectification
Kasper Poulsen, Alan C. Santos, Lasse B. Kristensen +1
Quantum mechanics dictates the band-structure of materials that is essential for functional electronic components. With increased miniaturization of devices, it becomes possible to…
Generation of spin currents by a temperature gradient in a two-terminal device
R. E. Barfknecht, A. Foerster, N. T. Zinner +1
Theoretical and experimental studies of the interaction between spins and temperature are vital for the development of spin caloritronics, as they dictate the design of future devi…
