Contactless cavity sensing of superfluid stiffness in atomically thin 4Hb-TaS
Trevor Chistolini, Ha-Leem Kim, Qiyu Wang +13
The exceptional tunability of two-dimensional van der Waals materials offers unique opportunities for exploring novel superconducting phases. However, in such systems, the measurem…
A Qutrit Time Crystal Stabilized with Native Chiral Interactions
Noah Goss, Nishchay Suri, Brian Marinelli +11
Periodically driven quantum many-body systems can spontaneously break discrete time-translation symmetry, realizing discrete time crystals. To date, both experimental and theoretic…
Flux Pumped Kerr-Free Parametric Amplifier
Kagan Yanik, Irwin Huang, Bibek Bhandari +7
We propose a flux-pumped superconducting parametric amplifier based on symmetrically threaded superconducting quantum interference devices (SQUIDs) that achieves a Kerr-free operat…
The superconducting grid-states qubit
Long B. Nguyen, Hyunseong Kim, Dat T. Le +9
Decoherence errors arising from noisy environments remain a central obstacle to progress in quantum computation and information processing. Quantum error correction (QEC) based on…
Tunable Superconducting Quantum Interference Device Coupler for Fluxonium Qubits
Abhishek Chakraborty, Bibek Bhandari, D. Dominic Briseño-Colunga +7
Tunable couplers enable high-fidelity two-qubit gates leveraging high on/off coupling ratios and reduced crosstalk within a single design. We investigate a galvanically connected d…
Heisenberg-limited calibration of entangling gates with robust phase estimation
Kenneth Rudinger, J. P. Marceaux, Akel Hashim +3
The calibration of high-quality two-qubit entangling gates is an essential component in engineering large-scale, fault-tolerant quantum computers. However, many standard calibratio…
