Hamiltonian Simulation Algorithms for Near-Term Quantum Hardware

Understand

The quantum circuit model is the de-facto way of designing quantum algorithms.

• Yet any level of abstraction away from the underlying hardware incurs overhead.
• In the era of near-term, noisy, intermediate-scale quantum (NISQ) hardware with severely restricted resources, this overhead may be unjustifiable.
• In this work, we develop quantum algorithms for Hamiltonian simulation "one level below" the circuit model, exploiting the underlying control over qubit interactions available in principle in most quantum hardware implementations.
