Trapped ions offer long coherence times and high fidelity, programmable quantum
operations, making them a promising platform for quantum simulation of condensed matter …

We describe and benchmark a new quantum charge-coupled device (QCCD) trapped-ion
quantum computer based on a linear trap with periodic boundary conditions, which …

Midcircuit operations, such as qubit state measurement or reset, are central to many tasks in
quantum information science, including quantum computing, entanglement generation, and …

Long-range entanglement—the backbone of topologically ordered states—cannot be
created in finite time using local unitary circuits, or, equivalently, adiabatic state preparation …

In this work, we introduce an open-source suite of quantum application-oriented
performance benchmarks that is designed to measure the effectiveness of quantum …

The ground state of the spin-1 Affleck, Kennedy, Lieb, and Tasaki (AKLT) model is a
paradigmatic example of both a matrix product state and a symmetry-protected topological …

Quantum computers promise to efficiently simulate quantum dynamics, a classically
intractable task central to fields ranging from chemistry to high-energy physics. Yet, quantum …

Current benchmarks for midcircuit measurements (MCMs) are limited in scalability or the
types of error they can quantify, necessitating new techniques for quantifying MCM …

Quantum computers present a compelling platform for the study of open quantum systems,
namely, the nonunitary dynamics of a system. Here, we investigate and report digital …

The ability to selectively measure, initialize, and reuse qubits during a quantum circuit
enables a map** of the spatial structure of certain tensor-network states onto the …
