• Abstract summary: Quantum simulation is a foundational application for quantum computers. Existing simulation techniques are for the most part too intricate to implement on early fault-tolerant quantum hardware. We propose a quantum Hamiltonian dynamics simulation algorithm that aims to be both straightforward to implement and at the same time have near-optimal scaling in simulation precision.

• Abstract: Quantum simulation is a foundational application for quantum computers, projected to offer insights into complex quantum systems that are beyond the reach of classical computation. However, with the exception of Trotter-based methods which suffer from suboptimal scaling with respect to simulation precision, existing simulation techniques are for the most part too intricate to implement on early fault-tolerant quantum hardware. We propose a quantum Hamiltonian dynamics simulation algorithm that aims to be both straightforward to implement and at the same time have near-optimal scaling in simulation precision.

  Given a quantum circuit containing d tunable RZ gates and G-d Clifford gates, can a learner perform purely classical inference to efficiently predict its linear properties? We prove that the sample complexity scaling linearly in d is necessary and sufficient to achieve a small prediction error, while the corresponding computational complexity may scale exponentially in d. We devise a kernel-based learning model capable of trading off prediction error and computational complexity, transitioning from exponential to scaling in many practical settings.

  Quantum algorithms for quantum dynamics simulations are traditionally based on implementing a Trotter-approximation of the time-evolution operator. variational quantum algorithms have become an indispensable alternative, enabling small-scale simulations on present-day hardware. We show that, despite providing a clear reduction of quantum gate cost, the variational method in its current implementation is unlikely to lead to a quantum advantage.
