Reducing the amount of single-qubit rotations in VQE and related algorithms
S. E. Rasmussen, N. J. S. Loft, T. Bækkegaard +2
With the advent of hybrid quantum classical algorithms using parameterized quantum circuits the question of how to optimize these algorithms and circuits emerges. In this paper we…
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…
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…
