Three-mode tunable coupler for superconducting two-qubit gates
Elena Yu. Egorova, Alena S. Kazmina, Ilya A. Simakov +7
Building a scalable universal high-performance quantum processor is a formidable challenge. In particular, the problem of realizing fast high-perfomance two-qubit gates of high-fid…
Demonstration of a parity-time symmetry breaking phase transition using superconducting and trapped-ion qutrits
Alena S. Kazmina, Ilia V. Zalivako, Alexander S. Borisenko +21
Scalable quantum computers hold the promise to solve hard computational problems, such as prime factorization, combinatorial optimization, simulation of many-body physics, and quan…
Non-degenerate parametric amplifiers based on dispersion engineered Josephson junction arrays
Patrick Winkel, Ivan Takmakov, Dennis Rieger +12
Determining the state of a qubit on a timescale much shorter than its relaxation time is an essential requirement for quantum information processing. With the aid of a new type of…
Design of an inductively shunted transmon qubit with tunable transverse and longitudinal coupling
Susanne Richer
This thesis is set in the framework of superconducting transmon-type qubit architectures with special focus on two important types of coupling between qubits and harmonic resonator…
Inductively shunted transmon qubit with tunable transverse and longitudinal coupling
Susanne Richer, Nataliya Maleeva, Sebastian T. Skacel +2
We present the design of an inductively shunted transmon qubit with flux-tunable coupling to an embedded harmonic mode. This circuit construction offers the possibility to flux-cho…
An argon ion beam milling process for native layers enabling coherent superconducting contacts
Lukas Grünhaupt, Uwe von Lüpke, Daria Gusenkova +8
We present an argon ion beam milling process to remove the native oxide layer forming on aluminum thin films due to their exposure to atmosphere in between lithographic steps. Our…
