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…

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…

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…
