Time-dependent Schrieffer-Wolff-Lindblad Perturbation Theory: measurement-induced dephasing and second-order Stark shift in dispersive readout
Moein Malekakhlagh, Easwar Magesan, Luke C. G. Govia
We develop a time-dependent Schrieffer-Wolff-Lindblad perturbation theory to study effective interactions for driven open quantum systems. The starting point of our analysis is a g…
Mitigating off-resonant error in the cross-resonance gate
Moein Malekakhlagh, Easwar Magesan
Off-resonant error for a driven quantum system refers to interactions due to the input drives having non-zero spectral overlap with unwanted system transitions. For the cross-reson…
Quantum crosstalk cancellation for fast entangling gates and improved multi-qubit performance
K. X. Wei, E. Magesan, I. Lauer +14
Quantum computers built with superconducting artificial atoms already stretch the limits of their classical counterparts. While the lowest energy states of these artificial atoms s…
Demonstration of a High-Fidelity CNOT for Fixed-Frequency Transmons with Engineered ZZ Suppression
A. Kandala, K. X. Wei, S. Srinivasan +6
Improving two-qubit gate performance and suppressing crosstalk are major, but often competing, challenges to achieving scalable quantum computation. In particular, increasing the c…
Laser-annealing Josephson junctions for yielding scaled-up superconducting quantum processors
Jared B. Hertzberg, Eric J. Zhang, Sami Rosenblatt +8
As superconducting quantum circuits scale to larger sizes, the problem of frequency crowding proves a formidable task. Here we present a solution for this problem in fixed-frequenc…
Reducing unitary and spectator errors in cross resonance with optimized rotary echoes
Neereja Sundaresan, Isaac Lauer, Emily Pritchett +3
We present an improvement to the cross resonance gate realized with the addition of resonant, target rotary pulses. These pulses, applied directly to the target qubit, are simultan…
