Robust design under uncertainty in quantum error mitigation
Maksym Prodius, Piotr Czarnik, Michael McKerns +2
Error mitigation techniques are crucial to achieving near-term quantum advantage. Classical post-processing of quantum computation outcomes is a popular approach for error mitigati…
Thresholded Quantum Sensing with a Frustrated Kitaev Trimer
C. Huerta Alderete, Anubhav Kumar Srivastava, Bharath Hebbe Madhusudhana +1
We investigate the response of a Ramsey interferometric quantum sensor based on a frustrated, three-spin system (a Kitaev trimer) to a classical time-dependent field (signal). The…
Randomized adiabatic quantum linear solver algorithm with optimal complexity scaling and detailed running costs
David Jennings, Matteo Lostaglio, Sam Pallister +2
Solving linear systems of equations is a fundamental problem with a wide variety of applications across many fields of science, and there is increasing effort to develop quantum li…
Improving the efficiency of learning-based error mitigation
Piotr Czarnik, Michael McKerns, Andrew T. Sornborger +1
Error mitigation will play an important role in practical applications of near-term noisy quantum computers. Current error mitigation methods typically concentrate on correction qu…
Large-scale simulations of Floquet physics on near-term quantum computers
Timo Eckstein, Refik Mansuroglu, Piotr Czarnik +5
Periodically driven quantum systems exhibit a diverse set of phenomena but are more challenging to simulate than their equilibrium counterparts. Here, we introduce the Quantum High…
The cost of solving linear differential equations on a quantum computer: fast-forwarding to explicit resource counts
David Jennings, Matteo Lostaglio, Robert B. Lowrie +2
How well can quantum computers simulate classical dynamical systems? There is increasing effort in developing quantum algorithms to efficiently simulate dynamics beyond Hamiltonian…
