Deterministic loading and phase shaping of microwaves onto a single artificial atom
W. -J. Lin, Y. Lu, P. Y. Wen +12
Loading quantum information deterministically onto a quantum node is an important step towards a quantum network. Here, we demonstrate that coherent-state microwave photons, with a…
Ultimate quantum limit for amplification: a single atom in front of a mirror
Emely Wiegand, Ping-Yi Wen, Per Delsing +2
We investigate three types of amplification processes for light fields coupling to an atom near the end of a one-dimensional semi-infinite waveguide. We consider two setups where a…

Shahnawaz Ahmed, Carlos Sánchez Muñoz, Franco Nori +1
We apply deep-neural-network-based techniques to quantum state classification and reconstruction. We demonstrate high classification accuracies and reconstruction fidelities, even…
Transmon in a semi-infinite high-impedance transmission line -- appearance of cavity modes and Rabi oscillations
Emely Wiegand, Benjamin Rousseaux, Göran Johansson
In this letter, we investigate the dynamics of a single superconducting artificial atom capacitively coupled to a transmission line with a characteristic impedance comparable or la…
Qubit Motion as a Microscopic Model for the Dynamical Casimir Effect
Andrés Agustí, Laura García-Álvarez, Enrique Solano +1
The generation of photons from the vacuum by means of the movement of a mirror is known as the dynamical Casimir effect (DCE). In general, this phenomenon is effectively described…

We establish a testbed system for the development of high-sensitivity Electron Spin Resonance (ESR) techniques for small samples at cryogenic temperatures. Our system consists of a…
Listening to the quantum vacuum: a perspective on the dynamical Casimir effect
Gheorghe Sorin Paraoanu, Göran Johansson
Modern quantum field theory has offered us a very intriguing picture of empty space. The vacuum state is no longer an inert, motionless state. We are instead dealing with an entity…

We use the Variational Quantum Eigensolver (VQE) as implemented in the Qiskit software package to compute the ground state energy of small molecules derived from water, HO, and…
QuTiP-BoFiN: A bosonic and fermionic numerical hierarchical-equations-of-motion library with applications in light-harvesting, quantum control, and single-molecule electronics
Neill Lambert, Tarun Raheja, Simon Cross +5
The "hierarchical equations of motion" (HEOM) method is a powerful exact numerical approach to solve the dynamics and find the steady-state of a quantum system coupled to a non-Mar…
Stochastic Thermodynamic Cycles of a Mesoscopic Thermoelectric Engine

We analyze a steady-state thermoelectric engine, whose working substance consists of two capacitively coupled quantum dots. One dot is tunnel-coupled to a hot reservoir serving as…
Wigner negativity in the steady-state output of a Kerr parametric oscillator
Ingrid Strandberg, Göran Johansson, Fernando Quijandría
The output field from a continuously driven linear parametric oscillator may exhibit considerably more squeezing than the intracavity field. Inspired by this fact, we explore the n…
