Optimizing Pulse Shapes of an Echoed Conditional Displacement Gate in a Superconducting Bosonic System
Echoed conditional displacement (ECD) gates for bosonic systems have become the key element for real-time quantum error correction beyond the break-even point. These gates are characterized
On „Consistent Quantization of Nearly Singular Superconducting Circuits“
The analysis conducted by Rymarz and DiVincenzo (Phys. Rev. X 13, 021017 (2023)) regarding quantization of superconducting circuits is insufficient to justify their general conclusions,
Deterministic remote entanglement using a chiral quantum interconnect
Quantum interconnects facilitate entanglement distribution between non-local computational nodes. For superconducting processors, microwave photons are a natural means to mediate this

Enhanced Superconducting Qubit Performance Through Ammonium Fluoride Etch
The performance of superconducting qubits is often limited by dissipation and two-level systems (TLS) losses. The dominant sources of these losses are believed to originate from amorphous

Fabrication and characterization of low-loss Al/Si/Al parallel plate capacitors for superconducting quantum information applications
Increasing the density of superconducting circuits requires compact components, however, superconductor-based capacitors typically perform worse as dimensions are reduced due to loss
Complete Self-Testing of a System of Remote Superconducting Qubits
Self-testing protocols enable the certification of quantum systems in a device-independent manner, i.e. without knowledge of the inner workings of the quantum devices under test. Here,

Proposal for Superconducting Quantum Networks Using Multi-Octave Transduction to Lower Frequencies
We propose networking superconducting quantum circuits by transducing their excitations (typically 4-8 GHz) to 100-500 MHz photons for transmission via cryogenic coaxial cables. Counter-intuitively,

A single-photon microwave switch with recoverable control photon
Scalable quantum technologies may be applied in prospective architectures employing traditional information processing elements, such as transistors, rectifiers, or switches modulated
Modular quantum processor with an all-to-all reconfigurable router
Superconducting qubits provide a promising approach to large-scale fault-tolerant quantum computing. However, qubit connectivity on a planar surface is typically restricted to only
Search for QCD axion dark matter with transmon qubits and quantum circuit
We propose a direct axion dark matter (DM) search using superconducting transmon qubits as quantum sensors. With an external magnetic field applied, axion DM generates an oscillating
