FIREQ: FPGA Instrumentation for Readout and Qubit control
Giuseppe La Capra, Fabio Calabrese, Giorgio D'Amico +8
We present FIREQ (FPGA Instrumentation for Readout and Qubit control), an open-source RFSoC-based framework for the control and readout of superconducting qubits. FIREQ combines a…
Operation of Unshielded Kinetic-Inductance Traveling-Wave Parametric Amplifiers in Multi-Tesla Fields
Christian Boutan, Erik Lentz, Corwin Shiu +12
Cryogenic parametric amplifiers are used to amplify radio-frequency signals for a range of applications in basic and applied science. Both Josephson Parametric Amplifiers and Josep…
Hardware-Aware Fermion-to-Qubit Mappings for Simulating the 2D Hubbard Model on Heavy-Hexagon Quantum Processors
Alessio Esposito, Andrea Giachero, Zoltàn Zimboràs +1
Quantum simulation of strongly correlated fermionic systems is among the most promising near- term applications of quantum computing, but its practical efficiency depends criticall…
Demonstration of a cryogenic, switchable electron source for low-temperature detector calibration
D. A. Bennett, M. Borghesi, P. Campana +17
We present the realization of a prototype of a compact, switchable electron source operating at cryogenic temperatures, demonstrated at energies ranging from 100 eV to 300 eV, and…
Multi-stage Quantum Amplifier Readout Chain
Logan Howe, Andrea Giachero, Michael Vissers +5
Multi-stage cryogenic readout chains with a wide bandwidth and added noise within a few quanta of the quantum limit are frequently constructed using traveling-wave parametric ampli…
When is randomization advantageous in quantum simulation?
Francesco Paganelli, Michele Grossi, Andrea Giachero +2
We study the regimes in which Hamiltonian simulation benefits from randomization. We introduce a sparse-QSVT construction based on composite stochastic decompositions, where domina…
