Deterministic generation of shaped single microwave photons using a parametrically driven coupler
Jiaying Yang, Axel Eriksson, Mohammed Ali Aamir +5
A distributed quantum computing system requires a quantum communication channel between spatially separated processing units. In superconducting circuits, such a channel can be rea…
Simple, reliable and noise-resilient continuous-variable quantum state tomography with convex optimization
Ingrid Strandberg
Precise reconstruction of unknown quantum states from measurement data, a process commonly called quantum state tomography, is a crucial component in the development of quantum inf…
Multipartite entanglement in a microwave frequency comb
Shan W. Jolin, Gustav Andersson, J. C. Rivera Hernández +6
Significant progress has been made with multipartite entanglement of discrete qubits, but continuous variable systems may provide a more scalable path toward entanglement of large…
Robust preparation of Wigner-negative states with optimized SNAP-displacement sequences
Marina Kudra, Mikael Kervinen, Ingrid Strandberg +13
Hosting non-classical states of light in three-dimensional microwave cavities has emerged as a promising paradigm for continuous-variable quantum information processing. Here we ex…
Propagating Wigner-Negative States Generated from the Steady-State Emission of a Superconducting Qubit
Yong Lu, Ingrid Strandberg, Fernando Quijandría +3
We experimentally demonstrate the steady-state generation of propagating Wigner-negative states from a continuously driven superconducting qubit. We reconstruct the Wigner function…
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…
Numerical study of Wigner negativity in one-dimensional steady-state resonance fluorescence
Ingrid Strandberg, Yong Lu, Fernando Quijandría +1
In a numerical study, we investigate the steady-state generation of nonclassical states of light from a coherently driven two-level atom in a one-dimensional waveguide. Specificall…
PennyLane: Automatic differentiation of hybrid quantum-classical computations
Ville Bergholm, Josh Izaac, Maria Schuld +65
PennyLane is a Python 3 software framework for differentiable programming of quantum computers. The library provides a unified architecture for near-term quantum computing devices,…
Steady-state generation of Wigner negative states in 1D resonance fluorescence
Fernando Quijandría, Ingrid Strandberg, Göran Johansson
In this work we demonstrate numerically that the nonlinearity provided by a continuously driven two-level system (TLS) allows for the generation of Wigner-negative states of the el…
