Fast universal control of a flux qubit via exponentially tunable wave-function overlap
Svend Krøjer, Anders Enevold Dahl, Kasper Sangild Christensen +2
Fast, high fidelity control and readout of protected superconducting qubits are fundamentally challenging due to their inherent insensitivity. We propose a flux qubit variation whi…
Scheme for parity-controlled multi-qubit gates with superconducting qubits
Kasper Sangild Christensen, Nikolaj Thomas Zinner, Morten Kjaergaard
Multi-qubit parity measurements are at the core of many quantum error correction schemes. Extracting multi-qubit parity information typically involves using a sequence of multiple…
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…
Native three-body interaction in superconducting circuits
Simon Panyella Pedersen, Kasper Sangild Christensen, Nikolaj Thomas Zinner
We show how a superconducting circuit consisting of three identical, non-linear oscillators in series considered in terms of its electrical modes can implement a strong, native thr…
Quantum thermal transistor in superconducting circuits
Marco Majland, Kasper Sangild Christensen, Nikolaj Thomas Zinner
Logical devices based on electrical currents are ubiquitous in modern society. However, digital logic does have some drawbacks such as a relatively high power consumption. It is th…
A coherent router for quantum networks
K. S. Christensen, S. E. Rasmussen, D. Petrosyan +1
Scalable quantum information processing will require quantum networks of qubits with the ability to coherently transfer quantum states between the desired sender and receiver nodes…
