Single-shot Quantum State Classification via Nonlinear Quantum Amplification
Elif Cüce, Elif Cüce, Saeed A. Khan +4
Quantum amplifiers are intrinsically nonlinear systems whose performance limits are set by quantum mechanics. In quantum measurement, amplifier operation is conventionally optimize…
High-fidelity Quantum Readout Processing via an Embedded SNAIL Amplifier
Leon Bello, Boris Mesits, Michael Hatridge +1
Scalable, high-fidelity quantum-state readout remains a central challenge in the development of large-scale superconducting quantum processors. Conventional dispersive readout arch…
Fast superconducting qubit control with sub-harmonic drives
Mingkang Xia, Chao Zhou, Chenxu Liu +8
Increasing the fidelity of single-qubit gates requires a combination of faster pulses and increased qubit coherence. However, with resonant qubit drive via a capacitively coupled p…
Electron spin dynamics guide cell motility
Kai Wang, Gabrielle Gilmer, Matheus Candia Arana +13
Diverse organisms exploit the geomagnetic field (GMF) for migration. Migrating birds employ an intrinsically quantum mechanical mechanism for detecting the geomagnetic field: absor…
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…
