Big cats: entanglement in 120 qubits and beyond
Ali Javadi-Abhari, Simon Martiel, Alireza Seif +2
Entanglement is the quintessential quantum phenomenon and a key enabler of quantum algorithms. The ability to faithfully entangle many distinct particles is often used as a benchma…
Improved Quantum Computation using Operator Backpropagation
Bryce Fuller, Minh C. Tran, Danylo Lykov +10
Decoherence of quantum hardware is currently limiting its practical applications. At the same time, classical algorithms for simulating quantum circuits have progressed substantial…
Dimensionality reduction for closed-loop quantum gate calibration
Emma Berger, Vivek Maurya, Z. M. McIntyre +3
Numerical gate design typically makes use of high-dimensional parameterizations enabling sophisticated, highly expressive control pulses. Developing efficient experimental calibrat…
Native two-qubit gates in fixed-coupling, fixed-frequency transmons beyond cross-resonance interaction
Ken Xuan Wei, Isaac Lauer, Emily Pritchett +3
Fixed-frequency superconducting qubits demonstrate remarkable success as platforms for stable and scalable quantum computing. Cross-resonance gates have been the workhorse of fixed…
Characterizing non-Markovian Off-Resonant Errors in Quantum Gates
Ken Xuan Wei, Emily Pritchett, David M. Zajac +2
As quantum gates improve, it becomes increasingly difficult to characterize the remaining errors. Here we describe a class of coherent non-Markovian errors -- excitations due to an…
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…
