A Solvable Model for Decoupling of Interacting Clusters
Artem G. Volosniev, Aksel S. Jensen, Nathan L. Harshman +2
We consider M clusters of interacting particles, whose in-group interactions are arbitrary, and inter-group interactions are approximated by oscillator potentials. We show that the…
Quantum interference device for controlled two-qubit operations
Niels Jakob Søe Loft, Morten Kjaergaard, Lasse Bjørn Kristensen +5
Universal quantum computing relies on high-fidelity entangling operations. Here we demonstrate that four coupled qubits can operate as a quantum gate, where two qubits control the…
A controllable two-qubit swapping gate using superconducting circuits
S. E. Rasmussen, K. S. Christensen, N. T. Zinner
In this paper we investigate a linear chain of qubits and determine that it can be configured into a conditional two-qubit swapping gate, where the first and last qubits of the cha…
Realizing time crystals in discrete quantum few-body systems
R. E. Barfknecht, S. E. Rasmussen, A. Foerster +1
The exotic phenomenon of time translation symmetry breaking under periodic driving - the time crystal - has been shown to occur in many-body systems even in clean setups where diso…
Realization of efficient quantum gates with a superconducting qubit-qutrit circuit
T. Bækkegaard, L. B. Kristensen, N. J. S. Loft +3
Building a quantum computer is a daunting challenge since it requires good control but also good isolation from the environment to minimize decoherence. It is therefore important t…
