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 …

We propose a general framework for using local measurements, local unitaries, and
nonlocal classical communication to construct quantum channels, which can efficiently …

We demonstrate high-fidelity repetitive measurements of nuclear spin qubits in an array of
neutral ytterbium-171 (171 Yb) atoms. We show that the qubit state can be measured with a …

Adaptive quantum circuits, which combine local unitary gates, midcircuit measurements, and
feedforward operations, have recently emerged as a promising avenue for efficient state …

Projective measurements in random quantum circuits lead to a rich breadth of entanglement
phases and extend the realm of nonunitary quantum dynamics. Here, we explore the …

Preparing quantum states across many qubits is necessary to unlock the full potential of
quantum computers. However, a key challenge is to realize efficient preparation protocols …

Although tensor network states constitute a broad range of exotic quantum states, their
realization is challenging and often requires resources whose depth scales with system size …

Topological phases of matter offer a promising platform for quantum computation and
quantum error correction. Nevertheless, unlike its counterpart in pure states, descriptions of …

Adaptive quantum circuits, in which unitary operations, measurements, and feedback are
used to steer quantum many-body systems, provide an exciting opportunity to generate …

In the era of noisy, intermediate-scale quantum (NISQ) devices, the efficient preparation of
many-body resource states is a task of paramount importance. In this paper we focus on the …
