Architectural scaling tradeoffs in modular 3D bosonic quantum processors
Shaojiang Zhu, Ugur Alyanak, Tanay Roy +7
We propose a modular three-dimensional bosonic quantum processor built from repeatable coupled-cavity modules linked by configurable interconnect networks. Using hardware-motivated…
Universal Jaynes-Cummings Control of an Oscillator
Jordan Huang, Ethan Kasaba, Thomas J. DiNapoli +2
The Jaynes-Cummings (JC) interaction-the coherent exchange of excitations between a two-level system and a harmonic oscillator-is one of the fundamental interactions of quantum opt…
Universal monitored dynamics in multimode bosonic systems
Shivam Patel, Catherine McCarthy, Ahana Chakraborty +5
We propose a route to study monitored many-body dynamics in multimode bosonic systems using circuit quantum electrodynamics. In this experimental setting, we construct several boso…
A Cascaded Random Access Quantum Memory
Ziqian Li, Eesh Gupta, Fang Zhao +7
Dynamic random access memory (DRAM) is critical to classical computing but notably absent in current superconducting quantum processors. Integrating high-coherence memory units wou…
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…
Floquet-engineered fast SNAP gates in weakly coupled circuit-QED systems
Xinyuan You, Andy C. Y. Li, Tanay Roy +5
Superconducting cavities with high quality factors, coupled to a fixed-frequency transmon, provide a state-of-the-art platform for quantum information storage and manipulation. The…
