Editor's note: As an emerging technology, quantum computing brings unique promises in
creating a fundamentally different paradigm of information processing. This article reviews …

Building a quantum computer that surpasses the computational power of its classical
counterpart is a great engineering challenge. Quantum software optimizations can provide …

We propose an experimental scheme to realize a nanoheat engine with a single ion. An Otto
cycle may be implemented by confining the ion in a linear Paul trap with tapered geometry …

Quantum teleportation is the faithful transfer of quantum states between systems, relying on
the prior establishment of entanglement and using only classical communication during the …

We demonstrate the use of trapped ytterbium ions as quantum bits for quantum information
processing. We implement fast, efficient state preparation and state detection of the first …

The result of a lecture series, this textbook is oriented towards students and newcomers to
the field and discusses theoretical foundations as well as experimental realizations in detail …

Taking advantage of nuclear spins for electronic structure analysis, magnetic resonance
imaging, and quantum devices hinges on knowledge and control of the surrounding atomic …

The study of individual quantum systems in solids, for use as quantum bits (qubits) and
probes of decoherence, requires protocols for their initialization, unitary manipulation, and …

We report the electromagnetically-induced-transparency (EIT) cooling of a large trapped
Yb+ 171 ion chain to the quantum ground state. Unlike conventional EIT cooling, we engage …

Favored schemes for trapped-ion quantum logic gates use bichromatic laser fields to couple
internal qubit states with external motion through a “spin-dependent force.” We introduce a …
