Magnetic Phase Diagrams and Spin Hamiltonian of Monoclinic -RuCl from Angle-Dependent Torque Studies
Daniel Antoniou, Danrui Ni, John S. Pearce +3
The layered honeycomb -RuCl has been much explored as a candidate to display unconventional cooperative magnetism between spin-orbit entangled Ru ma…
Anomalous Thermal Conductivity Reversal Driven by a Fluctuating Charge Density Wave
Han Huang, Jinghang Dai, Joyce Christiansen-Salameh +14
For more than a century, the lattice thermal conductivity of crystalline solids has been known to decrease with increasing temperature, as the phonons that carry heat scatter more…
Quantifying surface losses in superconducting aluminum microwave resonators
Elizabeth Hedrick, Faranak Bahrami, Alexander C. Pakpour-Tabrizi +11
The recent realization of millisecond-scale coherence with tantalum-on-silicon transmon qubits showed that depositing the Al/AlOx/Al Josephson junction in a high purity, ultrahigh…
Beta Tantalum Transmon Qubits with Quality Factors Approaching 10 Million
Atharv Joshi, Apoorv Jindal, Paal H. Prestegaard +9
Tantalum-based transmon qubits are a promising platform for building large-scale quantum processors. So far, these qubits have been made from tantalum films grown exclusively in th…
van der Waals Nanoreactors
Zhaoyi Joy Zheng, Haosen Guan, Danrui Ni +11
Advancing the chemical synthesis of crystals is important for both fundamental research and practical applications of quantum materials. While established bulk-phase and thin-film…
Superconducting Gap Engineering in Tantalum-Alloy-Based Resonators
Chen Yang, Faranak Bahrami, Guangming Cheng +7
Utilizing tantalum (Ta) in superconducting circuits has led to significant improvements, such as high qubit lifetimes and quality factors in both qubits and resonators, underscorin…
Suppression of Intertwined Density Waves in LaNiCuO
Stephen Zhang, Danrui Ni, Ruyi Ke +3
Superconductivity in LaNiO has been reported to emerge upon suppression of intertwined spin and charge density wave (SDW/CDW) order, suggesting a possible connec…
2D transmons with lifetimes and coherence times exceeding 1 millisecond
Matthew P. Bland, Faranak Bahrami, Jeronimo G. C. Martinez +14
Materials improvements are a powerful approach to reducing loss and decoherence in superconducting qubits because such improvements can be readily translated to large scale process…
Vortex Motion Induced Losses in Tantalum Resonators
Faranak Bahrami, Matthew P. Bland, Nana Shumiya +17
Tantalum (Ta) based superconducting circuits have been demonstrated to enable record qubit coherence times and quality factors, motivating a careful study of the microscopic origin…
Eliminating Surface Oxides of Superconducting Circuits with Noble Metal Encapsulation
Ray D. Chang, Nana Shumiya, Russell A. McLellan +15
The lifetime of superconducting qubits is limited by dielectric loss, and a major source of dielectric loss is the native oxide present at the surface of the superconducting metal.…
Anisotropy of the zigzag order in the Kitaev honeycomb magnet -RuBr
John S. Pearce, David A. S. Kaib, Zeyu Ma +5
Kitaev materials often order magnetically at low temperatures due to the presence of non-Kitaev interactions. Torque magnetometry is a very sensitive technique for probing the magn…
Anisotropic magnetic interactions in a candidate Kitaev spin liquid close to a metal-insulator transition
Zeyu Ma, Danrui Ni, David A. S. Kaib +6
In the Kitaev honeycomb model, spins coupled by strongly-frustrated anisotropic interactions do not order at low temperature but instead form a quantum spin liquid with spin fracti…
Spin-photon entanglement of a single Er ion in the telecom band
Mehmet T. Uysal, Łukasz Dusanowski, Haitong Xu +5
Long-distance quantum communication using quantum repeaters is an enabling technology for secure communication, distributed quantum computing and quantum-enhanced sensing and metro…
