Optical readout of a superconducting qubit using a piezo-optomechanical transducer
T. C. van Thiel, M. J. Weaver, F. Berto +17
Superconducting quantum processors have made significant progress in size and computing potential. However, the practical cryogenic limitations of operating large numbers of superc…
Qutrit Circuits and Algebraic Relations: A Pathway to Efficient Spin-1 Hamiltonian Simulation
Oluwadara Ogunkoya, Joonho Kim, Bo Peng +2
Quantum information processing has witnessed significant advancements through the application of qubit-based techniques within universal gate sets. Recently, exploration beyond the…
Modular Superconducting Qubit Architecture with a Multi-chip Tunable Coupler
Mark Field, Angela Q. Chen, Ben Scharmann +7
We use a floating tunable coupler to mediate interactions between qubits on separate chips to build a modular architecture. We demonstrate three different designs of multi-chip tun…
Extending relax-and-round combinatorial optimization solvers with quantum correlations
Maxime Dupont, Bhuvanesh Sundar
We introduce a relax-and-round approach embedding the quantum approximate optimization algorithm (QAOA) with layers. We show for many problems, including Sherrington-Kirk…
Quasiparticle spectroscopy in technologically-relevant niobium using London penetration depth measurements
Sunil Ghimire, Kamal R. Joshi, Amlan Datta +10
London penetration depth was measured in niobium foils, thin films, single crystals, and superconducting radio-frequency (SRF) cavity pieces cut out from different places. The low-…
Systematic Improvements in Transmon Qubit Coherence Enabled by Niobium Surface Encapsulation
Mustafa Bal, Akshay A. Murthy, Shaojiang Zhu +37
We present a novel transmon qubit fabrication technique that yields systematic improvements in T relaxation times. We fabricate devices using an encapsulation strategy that inv…
