Direct estimation of arbitrary observables of an oscillator
Tanjung Krisnanda, Fernando Valadares, Kyle Timothy Ng Chu +6
Quantum harmonic oscillators serve as fundamental building blocks for quantum information processing, particularly in the context of the bosonic circuit quantum electrodynamics (cQ…
Nonlinear Phase Gates Beyond the Lamb-Dicke Regime
Akram Kasri, Kimin Park, Radim Filip
Nonlinear phase gates are essential to achieve the universality of continuous-variable quantum processing and its applications. We present a deterministic protocol for generating n…
Qubit-parity interference despite unknown interaction phases
Kratveer Singh, Kimin Park, VojtÄch Å varc +5
Quantum interference between interacting systems is fundamental to basic science and quantum technology, but it typically requires precise control of the interaction phases of lase…
Scaling of multicopy constructive interference of Gaussian states
Matthieu Arnhem, Radim Filip
Quantum technology advances crucially depend on the scaling up of essential quantum resources. Their ideal multiplexing offers more significant gains in applications; however, the…
Quantum Phase Estimation Beyond the Gaussian Limit
Kimin Park, Tanjung Krisnanda, Yvonne Gao +1
Quantum metrology aims to enhance measurement precision beyond the standard quantum limit (SQL), the benchmark set by classical resources, enabling advances in sensing, imaging, an…
Realization of versatile and effective quantum metrology using a single bosonic mode
Xiaozhou Pan, Tanjung Krisnanda, Andrea Duina +6
Quantum metrology offers the potential to surpass its classical counterpart, pushing the boundaries of measurement precision toward the ultimate Heisenberg limit. This enhanced pre…
