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…
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…
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…
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…
