Quantum Enhanced Dark-Matter Search with Entangled Fock States in High-Quality Cavities
Benjamin Freiman, Xinyuan You, Andy C. Y. Li +5
We present a quantum-enhanced protocol for detecting wave-like dark matter using an array of entangled superconducting cavities initialized in an -photon Fock state. By dist…
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…
Crosstalk-Robust Quantum Control in Multimode Bosonic Systems
Xinyuan You, Yunwei Lu, Taeyoon Kim +10
High-coherence superconducting cavities offer a hardware-efficient platform for quantum information processing. To achieve universal operations of these bosonic modes, the requisit…
Demonstrating the Potential of Adaptive LMS Filtering on FPGA-Based Qubit Control Platforms for Improved Qubit Readout in 2D and 3D Quantum Processing Units
Hans Johnson, Nicholas Bornman, Taeyoon Kim +3
Advancements in quantum computing underscore the critical need for sophisticated qubit readout techniques to accurately discern quantum states. This abstract presents our research…
