Contacting Josephson Junctions via Airbridges in Superconducting Circuits
Prakiran Baidya, Momčilo Milosavljević, Murali Krishna Kurmapu +6
Superconducting circuit devices require electrical interconnects between different circuit elements on the chip, for which conventional device architectures use a combination of tw…
Calibrating Magnetic Flux Control in Superconducting Circuits by Compensating Distortions on Time Scales from Nanoseconds up to Tens of Microseconds
Christoph Hellings, Nathan Lacroix, Ants Remm +8
Fast tuning of the transition frequency of superconducting qubits using magnetic flux is essential, for example, for realizing high-fidelity two-qubit gates with low leakage or for…
Experimentally Informed Decoding of Stabilizer Codes Based on Syndrome Correlations
Ants Remm, Nathan Lacroix, Lukas Bödeker +9
High-fidelity decoding of quantum error correction codes relies on an accurate experimental model of the physical errors occurring in the device. Because error probabilities can de…
Deterministic generation of a 20-qubit two-dimensional photonic cluster state
James O'Sullivan, Kevin Reuer, Aleksandr Grigorev +11
Multidimensional cluster states are a key resource for robust quantum communication, measurement-based quantum computing and quantum metrology. Here, we present a device capable of…
Mitigating Losses of Superconducting Qubits Strongly Coupled to Defect Modes
Dante Colao Zanuz, Quentin Ficheux, Laurent Michaud +16
The dominant contribution to the energy relaxation of state-of-the-art superconducting qubits is often attributed to their coupling to an ensemble of material defects which behave…
Studying Light-Harvesting Models with Superconducting Circuits
Anton Potočnik, Arno Bargerbos, Florian A. Y. N. Schröder +9
The process of photosynthesis, the main source of energy in the animate world, converts sunlight into chemical energy. The surprisingly high efficiency of this process is believed…
Switching off energy decay channels in nanomechanical resonators
J. Guettinger, A. Noury, P. Weber +7
Energy decay plays a central role in a wide range of phenomena, such as optical emission, nuclear fission, and dissipation in quantum systems. Energy decay is usually described as…
Measurement of geometric dephasing using a superconducting qubit
S. Berger, M. Pechal, P. Kurpiers +7
A quantum system interacting with its environment is subject to dephasing which ultimately destroys the information it holds. Using a superconducting qubit, we experimentally show…
Exploring the Effect of Noise on the Berry Phase
S. Berger, M. Pechal, A. A. Abdumalikov +5
We make use of a superconducting qubit to study the effects of noise on adiabatic geometric phases. The state of the system, an effective spin one-half particle, is adiabatically g…
Characterizing Quantum Microwave Radiation and its Entanglement with Superconducting Qubits using Linear Detectors
C. Eichler, D. Bozyigit, A. Wallraff
Recent progress in the development of superconducting circuits has enabled the realization of interesting sources of nonclassical radiation at microwave frequencies. Here, we discu…
