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…
Two-Level System Spectroscopy from Correlated Multilevel Relaxation in Superconducting Qubits
Tanay Roy, Xinyuan You, David van Zanten +5
Transmon qubits are a cornerstone of modern superconducting quantum computing platforms. Temporal fluctuations of energy relaxation in these qubits are widely attributed to microsc…
Effect of metal encapsulation on bulk superconducting properties of niobium thin films used in qubits
Amlan Datta, Kamal R. Joshi, Sunil Ghimire +18
Niobium metal occupies nearly 100\% of the volume of a typical 2D transmon device. While the aluminum Josephson junction is of utmost importance, maintaining quantum coherence acro…
Two-tooth bosonic quantum comb for temporal-correlation sensing
Shaojiang Zhu, Xinyuan You, Alexander Romanenko +1
We characterize the causal structure of coherence transport in open bosonic systems using a two-tooth quantum comb. We show that, by mapping sequential interactions between a struc…
Coherence-Mediated Quantum Thermometry in a Hybrid Circuit-QED Architecture
Shaojiang Zhu, Xinyuan You, Alexander Romanenko +1
Quantum thermometry plays a critical role in the development of low-temperature sensors and quantum information platforms. In this work, we propose and theoretically analyze a hybr…
Analysis of RF Surface Loss in a Planar 2D Qubit
Andrei Lunin, Mustafa Bal, Akshay Murthy +3
The Josephson junction and shunt capacitor form a transmon qubit, which is the cornerstone of modern quantum computing platforms. For reliable quantum computing, it is important ho…
