The subject of quantum computing brings together ideas from classical information theory,
computer science, and quantum physics. This review aims to summarize not just quantum …

Advances in isolating, controlling and entangling quantum systems are transforming what
was once a curious feature of quantum mechanics into a vehicle for disruptive scientific and …

Methods for, and limitations to, the generation of entangled states of trapped atomic ions are
examined. As much as possible, state manipulations are described in terms of quantum …

In the past year many developments have taken place in the area of quantum error
corrections. Recently Shor showed how to perform fault tolerant quantum computation …

To date, quantum computation on real, physical devices has largely been limited to simple,
time-ordered sequences of unitary operations followed by a final projective measurement …

Quantum computing (QC) is a new paradigm offering the potential of exponential speedups
over classical computing for certain computational problems. Each additional qubit doubles …

Experimentally, secure quantum key distribution has been tested, using polarization or
phase of photons, for distance of 150 (200) km using standard optical fibres and for the …

In dynamic quantum circuits, classical information from midcircuit measurements is fed
forward during circuit execution. This emerging capability of quantum computers confers …

Quantum computers can execute algorithms that dramatically outperform classical
computation. As the best-known example, Shor discovered an efficient quantum algorithm …

Quantum tomography is the main method used to assess the quality of quantum information
processing devices. However, the amount of resources needed for quantum tomography is …
