All our former experience with application of quantum theory seems to say that what is
predicted by quantum formalism must occur in the laboratory. But the essence of quantum …

Quantum random sampling is the leading proposal for demonstrating a computational
advantage of quantum computers over classical computers. Recently the first large-scale …

Suppressing errors is the central challenge for useful quantum computing, requiring
quantum error correction (QEC),,,–for large-scale processing. However, the overhead in the …

The ability to engineer parallel, programmable operations between desired qubits within a
quantum processor is key for building scalable quantum information systems,. In most state …

Taking advantage of quantum mechanics for executing computational tasks faster than
classical computers or performing measurements with precision exceeding the classical …

Quantum correlations between two parties are essential for the argument of Einstein,
Podolsky, and Rosen in favor of the incompleteness of quantum mechanics. Schrödinger …

How can one prove that a given quantum state is entangled? In this paper we review
different methods that have been proposed for entanglement detection. We first explain the …

Driving a quantum system periodically in time can profoundly alter its long-time dynamics
and trigger topological order. Such schemes are particularly promising for generating …

We generate and characterize entangled states of a register of 20 individually controlled
qubits, where each qubit is encoded into the electronic state of a trapped atomic ion …

Entanglement is an important resource for quantum technologies. There are many ways
quantum systems can be entangled, ranging from the two-qubit case to entanglement in …
