Surpassing millisecond coherence times in on-chip superconducting quantum memories by optimizing materials, processes, and circuit design
Suhas Ganjam, Yanhao Wang, Yao Lu +10
The performance of superconducting quantum circuits for quantum computing has advanced tremendously in recent decades; however, a comprehensive understanding of relaxation mechanis…
Engineering of Niobium Surfaces Through Accelerated Neutral Atom Beam Technology For Quantum Applications
Soumen Kar, Conan Weiland, Chenyu Zhou +16
A major roadblock to scalable quantum computing is phase decoherence and energy relaxation caused by qubits interacting with defect-related two-level systems (TLS). Native oxides p…
Chemical profiles of the oxides on tantalum in state of the art superconducting circuits
Russell A. McLellan, Aveek Dutta, Chenyu Zhou +23
Over the past decades, superconducting qubits have emerged as one of the leading hardware platforms for realizing a quantum processor. Consequently, researchers have made significa…
Disentangling Losses in Tantalum Superconducting Circuits
Kevin D. Crowley, Russell A. McLellan, Aveek Dutta +17
Superconducting qubits are a leading system for realizing large scale quantum processors, but overall gate fidelities suffer from coherence times limited by microwave dielectric lo…
Performance Analysis of Superconductor-constriction-Superconductor Transmon Qubits
Mingzhao Liu, Charles T. Black
This work presents a computational analysis of a superconducting transmon qubit design, in which the superconductor-insulator-superconductor (SIS) Josephson junction is replaced by…
Generation of Ensembles of Individually Resolvable Nitrogen Vacancies Using Nanometer-Scale Apertures in Ultrahigh-Aspect Ratio Planar Implantation Masks
Igal Bayn, Edward H. Chen, Matthew E. Trusheim +9
A central challenge in developing magnetically coupled quantum registers in diamond is the fabrication of nitrogen vacancy (NV) centers with localization below ~20 nm to enable fas…
