Large-scale Lindblad learning from time-series data
Ewout van den Berg, Brad Mitchell, Ken Xuan Wei +1
In this work, we develop a protocol for learning a time-independent Lindblad model for operations that can be applied repeatedly on a quantum computer. The protocol is highly scala…
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…
