A one-way quantum computer.
TLDR
A scheme of quantum computation that consists entirely of one-qubit measurements on a particular class of entangled states, the cluster states, which are thus one-way quantum computers and the measurements form the program.Abstract:
We present a scheme of quantum computation that consists entirely of one-qubit measurements on a particular class of entangled states, the cluster states. The measurements are used to imprint a quantum logic circuit on the state, thereby destroying its entanglement at the same time. Cluster states are thus one-way quantum computers and the measurements form the program.read more

Quantum interference of photon pairs from two remote trapped atomic ions
Peter Maunz,D. L. Moehring,Steven Olmschenk,Kelly C. Younge,Dzmitry Matsukevich,Christopher Monroe +5 more
TL;DR: In this paper, the authors reported the pivotal element of their scheme in the observation of quantum interference between pairs of single photons emitted from two atomic ions residing in independent traps, and then detected appropriate photon coincidence events.

Mott-Hubbard transition of cold atoms in optical lattices
TL;DR: Greiner et al. as mentioned in this paper showed that in a one-dimensional dilute Bose-gas with a strong transverse confinement, even an arbitrary weak optical lattice is able to induce a Mott-like state with crystalline order, provided the dimensionless interactio np arameter is larger than a critical value of order one.

Scalable architecture for a room temperature solid-state quantum information processor
Norman Y. Yao,Liang Jiang,Alexey V. Gorshkov,Alexey V. Gorshkov,Peter Maurer,Geza Giedke,J. I. Cirac,Mikhail D. Lukin +7 more
TL;DR: This work proposes and analyses an architecture for a scalable, solid-state quantum information processor capable of operating at room temperature that alleviates the stringent constraints currently limiting the realization of scalable quantum processors and will provide fundamental insights into the physics of non-equilibrium many-body quantum systems.

Elementary gates for quantum computation.
Adriano Barenco,Charles H. Bennett,Richard Cleve,David P. DiVincenzo,Norman Margolus,Peter W. Shor,Tycho Sleator,John A. Smolin,Harald Weinfurter +8 more
TL;DR: U(2) gates are derived, which derive upper and lower bounds on the exact number of elementary gates required to build up a variety of two- and three-bit quantum gates, the asymptotic number required for n-bit Deutsch-Toffoli gates, and make some observations about the number of unitary operations on arbitrarily many bits.

Quantum information and computation
TL;DR: In information processing, as in physics, the classical world view provides an incomplete approximation to an underlying quantum reality that can be harnessed to break codes, create unbreakable codes, and speed up otherwise intractable computations.

Good quantum error-correcting codes exist
A. R. Calderbank,Peter W. Shor +1 more
TL;DR: The techniques investigated in this paper can be extended so as to reduce the accuracy required for factorization of numbers large enough to be difficult on conventional computers appears to be closer to one part in billions.
Journal ArticleDOI
Error Correcting Codes in Quantum Theory.
TL;DR: It is shown that a pair of states which are, in a certain sense, “macroscopically different,” can form a superposition in which the interference phase between the two parts is measurable, providing a highly stabilized “Schrodinger cat” state.

Demonstrating the viability of universal quantum computation using teleportation and single-qubit operations
TL;DR: It is shown that single quantum bit operations, Bell-basis measurements and certain entangled quantum states such as Greenberger–Horne–Zeilinger (GHZ) states are sufficient to construct a universal quantum computer.
