1. Quantum Computing in the NISQ era and beyond

   John Preskill · 2018 · Quantum · 8,668 cites

   Noisy Intermediate-Scale Quantum (NISQ) technology will be available in the near future. Quantum computers with 50-100 qubits may be able to perform tasks which surpass the capabilities of today's classical digital computers, but noise in quantum gates will limit the size of quantum circuits that can be executed reliably. NISQ devices will be useful tools for exploring many-body quantum physics, and may have other useful applications, but the 100-qubit quantum computer will not change the world right away - we should regard it as a significant step toward the more powerful quantum technologies of the future. Quantum technologists should continue to strive for more accurate quantum gates and,

2. Quantum cryptography

   Nicolas Gisin, G. Ribordy, Wolfgang Tittel, et al. · 2002 · Reviews of Modern Physics · 8,478 cites

   Quantum cryptography could well be the first application of quantum mechanics at the single-quantum level. The rapid progress in both theory and experiment in recent years is reviewed, with emphasis on open questions and technological issues.

3. The quantum internet

   H. J. Kimble · 2008 · Nature · 5,996 cites

4. Quantum information with continuous variables

   Samuel L. Braunstein, Peter van Loock · 2005 · Reviews of Modern Physics · 3,876 cites

   Quantum information is a rapidly advancing area of interdisciplinary research. It may lead to real-world applications for communication and computation unavailable without the exploitation of quantum properties such as nonorthogonality or entanglement. This article reviews the progress in quantum information based on continuous quantum variables, with emphasis on quantum optical implementations in terms of the quadrature amplitudes of the electromagnetic field.

6. Entanglement in Quantum Critical Phenomena

   Guifré Vidal, José I. Latorre, E. Rico, et al. · 2003 · Physical Review Letters · 2,861 cites

   Entanglement, one of the most intriguing features of quantum theory and a main resource in quantum information science, is expected to play a crucial role also in the study of quantum phase transitions, where it is responsible for the appearance of long-range correlations. We investigate, through a microscopic calculation, the scaling properties of entanglement in spin chain systems, both near and at a quantum critical point. Our results establish a precise connection between concepts of quantum information, condensed matter physics, and quantum field theory, by showing that the behavior of critical entanglement in spin systems is analogous to that of entropy in conformal field theories. We

7. Quantum State Transfer and Entanglement Distribution among Distant Nodes in a Quantum Network

   J. I. Cirac, P. Zoller, H. J. Kimble, et al. · 1997 · Physical Review Letters · 2,240 cites

   We propose a scheme to utilize photons for ideal quantum transmission between atoms located at spatially separated nodes of a quantum network. The transmission protocol employs special laser pulses that excite an atom inside an optical cavity at the sending node so that its state is mapped into a time-symmetric photon wave packet that will enter a cavity at the receiving node and be absorbed by an atom there with unit probability. Implementation of our scheme would enable reliable transfer or sharing of entanglement among spatially distant atoms.
