Squeezing enhanced sensing at an exceptional point
Changqing Wang, Deyuan Hu, Silvia Zorzetti +3
Pushing the boundaries of measurement precision is central for sensing and metrology, pursued by nonclassical resources such as squeezing, and non-Hermitian degeneracies with disti…
Ultracoherent superconducting cavity-based multiqudit platform with error-resilient control
Taeyoon Kim, Tanay Roy, Xinyuan You +26
Realizing the promise of quantum computing requires simultaneously increasing Hilbert-space size and coherence times. While qubit-based architectures have long been the dominant pa…
Entangling remote superconducting qubits via transducer-generated multi-time-bin states
Jing Wu, Changqing Wang, Andrew Cameron +1
Recent studies have shown long-distance entanglement using NV centers, atoms, and quantum dots with single-photon time-bin encoding. We propose a method to entangle remote supercon…
