Microwave Quantum Link between Superconducting Circuits Housed in Spatially Separated Cryogenic Systems
Paul Magnard, Simon Storz, Philipp Kurpiers +10
Superconducting circuits are a strong contender for realizing quantum computing systems, and are also successfully used to study quantum optics and hybrid quantum systems. However,…
Implementation of Conditional-Phase Gates based on tunable ZZ-Interactions
Michele C. Collodo, Johannes Herrmann, Nathan Lacroix +7
High fidelity two-qubit gates exhibiting low crosstalk are essential building blocks for gate-based quantum information processing. In superconducting circuits two-qubit gates are…
Parity Detection of Propagating Microwave Fields
Jean-Claude Besse, Simone Gasparinetti, Michele C. Collodo +5
The parity of the number of elementary excitations present in a quantum system provides important insights into its physical properties. Parity measurements are used, for example,…
Quantum communication with time-bin encoded microwave photons
Philipp Kurpiers, Marek Pechal, Baptiste Royer +10
Heralding techniques are useful in quantum communication to circumvent losses without resorting to error correction schemes or quantum repeaters. Such techniques are realized, for…
Challenging local realism with human choices
The BIG Bell Test Collaboration, C. Abellán, A. Acín +105
A Bell test is a randomized trial that compares experimental observations against the philosophical worldview of local realism. A Bell test requires spatially distributed entanglem…
Rapid high-fidelity multiplexed readout of superconducting qubits
Johannes Heinsoo, Christian Kraglund Andersen, Ants Remm +8
The duration and fidelity of qubit readout is a critical factor for applications in quantum information processing as it limits the fidelity of algorithms which reuse qubits after…
Fast and Unconditional All-Microwave Reset of a Superconducting Qubit
Paul Magnard, Philipp Kurpiers, Baptiste Royer +8
Active qubit reset is a key operation in many quantum algorithms, and particularly in error correction codes. Here, we experimentally demonstrate a reset scheme of a three level tr…
Deterministic Quantum State Transfer and Generation of Remote Entanglement using Microwave Photons
Philipp Kurpiers, Paul Magnard, Theo Walter +10
Sharing information coherently between nodes of a quantum network is at the foundation of distributed quantum information processing. In this scheme, the computation is divided int…
Single-Shot Quantum Non-Demolition Detection of Itinerant Microwave Photons
Jean-Claude Besse, Simone Gasparinetti, Michele C. Collodo +5
Single-photon detection is an essential component in many experiments in quantum optics, but remains challenging in the microwave domain. We realize a quantum non-demolition detect…
Realizing Rapid, High-Fidelity, Single-Shot Dispersive Readout of Superconducting Qubits
T. Walter, P. Kurpiers, S. Gasparinetti +8
The speed of quantum gates and measurements is a decisive factor for the overall fidelity of quantum protocols when performed on physical qubits with finite coherence time. Reducin…
Characterizing the attenuation of coaxial and rectangular microwave-frequency waveguides at cryogenic temperatures
P. Kurpiers, T. Walter, P. Magnard +2
Low-loss waveguides are required for quantum communication at distances beyond the chip-scale for any low-temperature solid-state implementation of quantum information processors.…
