Abstract summary: We estimate the resources required to prepare the ground state of a quantum many-body system on a quantum computer of intermediate size. We find that it reduces the circuit T-depth by a factor as large as $106$ for intermediate-size lattices.

Abstract: We estimate the resources required to prepare the ground state of a quantum many-body system on a quantum computer of intermediate size. This estimate is made possible using a combination of quantum many-body methods and analytic upper bounds. Our routine can also be used to optimize certain design parameters for specific problem instances. Lastly, we propose and benchmark an improved quantum state preparation procedure. We find that it reduces the circuit T-depth by a factor as large as $10^6$ for intermediate-size lattices.

Preparation of a target quantum many-body state on quantum simulators is one of the significant steps in quantum science and technology. With a small number of qubits, a few quantum states, such as the Greenberger-Horne-Zeilinger state, have been prepared, but fundamental difficulties in systems with many qubits remain. Here, we provide one algorithm with an implementation of a deep learning process and achieve to prepare the target ground states with many qubits.

State preparation in quantum algorithms for fragment-based quantum chemistry [0.0]
State preparation for quantum algorithms is crucial for achieving high accuracy in quantum chemistry. We compare two state preparation methods, quantum phase estimation (QPE) and direct initialization (DI) We find a trade-off between the methods, where DI requires fewer resources for smaller fragments, while QPE is more efficient for larger fragments.

Estimating many properties of a quantum state via quantum reservoir processing [2.5432391525687748]
We propose a general framework for constructing classical approximations of arbitrary quantum states with quantum reservoirs. A key advantage of our method is that only a single local measurement setting is required for estimating arbitrary properties. This estimation scheme is extendable to higher-dimensional systems and hybrid systems with non-identical local dimensions.

Assessing requirements to scale to practical quantum advantage [56.22441723982983]
We develop a framework for quantum resource estimation, abstracting the layers of the stack, to estimate resources required for large-scale quantum applications. We assess three scaled quantum applications and find that hundreds of thousands to millions of physical qubits are needed to achieve practical quantum advantage. A goal of our work is to accelerate progress towards practical quantum advantage by enabling the broader community to explore design choices across the stack.
