Encoding qubits in multimode grid states
Baptiste Royer, Shraddha Singh, Steven M. Girvin
Encoding logical quantum information in harmonic oscillator modes is a promising and hardware-efficient approach to the realization of a quantum computer. In this work, we propose…
Stabilization of Finite-Energy Gottesman-Kitaev-Preskill States
Baptiste Royer, Shraddha Singh, S. M. Girvin
We introduce a new approach to Gottesman-Kitaev-Preskill (GKP) states that treats their finite-energy version in an exact manner. Based on this analysis, we develop new qubit-oscil…
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,…
Demonstration of an All-Microwave Controlled-Phase Gate between Far Detuned Qubits
S. Krinner, P. Kurpiers, B. Royer +6
A challenge in building large-scale superconducting quantum processors is to find the right balance between coherence, qubit addressability, qubit-qubit coupling strength, circuit…
Quantum metamaterial for nondestructive microwave photon counting
Arne L. Grimsmo, Baptiste Royer, John Mark Kreikebaum +4
Detecting traveling photons is an essential primitive for many quantum information processing tasks. We introduce a single-photon detector design operating in the microwave domain,…
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…
