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…
Multi-frequency modes in superconducting resonators: Bridging frequency gaps in off-resonant couplings
Christian Kraglund Andersen, Klaus Mølmer
A Superconducting Quantum Interference Device (SQUID) inserted in a superconducting waveguide resonator imposes current and voltage boundary conditions that makes it suitable as a…
Comment on "Contextuality in Bosonic Bunching"
Malte C. Tichy, Christian Kraglund Andersen
Bosonic bunching occurs within quantum physics and can be mimicked classically by noncontextual hidden-variable models, which excludes this phenomenon as a means to prove stronger-…
Circuit QED flip-flop memory with all-microwave switching
Christian Kraglund Andersen, Klaus Mølmer
We present a theoretical proposal for a microwave driven circuit composed of superconducting resonators and qubits which shows a bistable behaviour, and we present a simple mechani…
