Engineering a multi-level bath for transmons with three-wave mixing and parametric drives
Xi Cao, Maria Mucci, Gangqiang Liu +2
A quantum system with a tunable bath temperature provides an additional degree of freedom for quantum simulators. Such a system can be realized by parametrically modulating the cou…
Simple, High Saturation Power, Quantum-limited, RF SQUID Array-based Josephson Parametric Amplifiers
Ryan Kaufman, Chenxu Liu, Katarina Cicak +7
High-fidelity quantum non-demolition qubit measurement is critical to error correction and rapid qubit feedback in large-scale quantum computing. High-fidelity readout requires pas…
Pump-efficient Josephson parametric amplifiers with high saturation power
Nicholas M. Hougland, Zhuan Li, Ryan Kaufman +4
Circuit QED based quantum information processing relies on low noise amplification for signal readout. In the realm of microwave superconducting circuits, this amplification is oft…
Experimental advances with the QICK (Quantum Instrumentation Control Kit) for superconducting quantum hardware
Chunyang Ding, Martin Di Federico, Michael Hatridge +14
The QICK is a standalone open source qubit controller that was first introduced in 2022. In this follow-up work, we present recent experimental use cases that the QICK uniquely ena…
Practical Trainable Temporal Postprocessor for Multistate Quantum Measurement
Saeed A. Khan, Ryan Kaufman, Boris Mesits +2
We develop and demonstrate a trainable temporal post-processor (TPP) harnessing a simple but versatile machine learning algorithm to provide optimal processing of quantum measureme…
MIRAGE: Quantum Circuit Decomposition and Routing Collaborative Design using Mirror Gates
Evan McKinney, Michael Hatridge, Alex K. Jones
Building efficient large-scale quantum computers is a significant challenge due to limited qubit connectivities and noisy hardware operations. Transpilation is critical to ensure t…
