The waves-in-space Purcell effect for superconducting qubits
Param Patel, Mingkang Xia, Chao Zhou +5
Quantum information processing, especially with quantum error correction, requires both long-lived qubits and fast, quantum non-demolition readout. In superconducting circuits this…
Bias-preserving and error-detectable entangling operations in a superconducting dual-rail system
Nitish Mehta, James D. Teoh, Taewan Noh +69
For useful quantum computation, error-corrected machines are required that can dramatically reduce the inevitable errors experienced by physical qubits. While significant progress…
Demonstrating a superconducting dual-rail cavity qubit with erasure-detected logical measurements
Kevin S. Chou, Tali Shemma, Heather McCarrick +31
A critical challenge in developing scalable error-corrected quantum systems is the accumulation of errors while performing operations and measurements. One promising approach is to…
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…
Co-Designed Architectures for Modular Superconducting Quantum Computers
Evan McKinney, Mingkang Xia, Chao Zhou +3
Noisy, Intermediate Scale Quantum (NISQ) computers have reached the point where they can show the potential for quantum advantage over classical computing. Unfortunately, NISQ mach…
Realizing all-to-all couplings among detachable quantum modules using a microwave quantum state router
Chao Zhou, Pinlei Lu, Matthieu Praquin +8
One of the primary challenges in realizing large-scale quantum processors is the realization of qubit couplings that balance interaction strength, connectivity, and mode confinemen…
Noise reduction in qubit readout with a two-mode squeezed interferometer
G. Liu, X. Cao, T. -C. Chien +3
Fault-tolerant quantum information processing with flawed qubits and gates requires highly efficient, quantum non-demolition (QND) qubit readout. In superconducting circuits, qubit…
Nearly quantum-limited Josephson-junction Frequency Comb synthesizer
Pinlei Lu, Saeed Khan, Tzu-Chiao Chien +5
While coherently-driven Kerr microcavities have rapidly matured as a platform for frequency comb formation, such microresonators generally possess weak Kerr coefficients; consequen…
Multiparametric Amplification and Qubit Measurement with a Kerr-free Josephson Ring Modulator
T. -C. Chien, O. Lanes, C. Liu +6
Josephson-junction based parametric amplifiers have become a ubiquitous component in superconducting quantum machines. Although parametric amplifiers regularly achieve near-quantum…
