Quandary: An open-source C++ package for high-performance optimal control of open quantum systems
Stefanie Günther, N. Anders Petersson, Jonathan L. Dubois
Quantum optimal control can be used to shape the control pulses for realizing unitary and non-unitary transformations of quantum states. These control pulses provide the fundamenta…
Quantum Optimal Control for Pure-State Preparation Using One Initial State
Stefanie Günther, N. Anders Petersson, Jonathan L. DuBois
This paper presents a framework for solving the pure-state preparation problem using numerical optimal control. As an example, we consider the case where a number of qubits are dis…
Low frequency correlated charge noise measurements across multiple energy transitions in a tantalum transmon
Daniel M. Tennant, Luis A. Martinez, Kristin M. Beck +5
Transmon qubits fabricated with tantalum metal have been shown to possess energy relaxation times greater than 300 s and, as such, present an attractive platform for high precis…
Control optimization for parametric hamiltonians by pulse reconstruction
Piero Luchi, Francesco Turro, Valentina Amitrano +5
Optimal control techniques provide a means to tailor the control pulses required to generate customized quantum gates, which helps to improve the resilience of quantum simulations…
Imaginary Time Propagation on a Quantum Chip
Francesco Turro, Alessandro Roggero, Valentina Amitrano +5
Evolution in imaginary time is a prominent technique for finding the ground state of quantum many-body systems, and the heart of a number of numerical methods that have been used w…
