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

Cluster-state quantum computation
TL;DR: In this article, a short introduction to and review of the cluster-state model of quantum computation is presented, in which coherent quantum information processing is accomplished via a sequence of single-qubit measurements applied to a fixed quantum state known as a cluster state.

Robustness and device independence of verifiable blind quantum computing
TL;DR: The robustness of the single server verifiable universal blind quantum computing protocol of Fitzsimons and Kashefi is proved in the most general scenario and the composition of this protocol with a device-independent state tomography protocol that is based on the rigidity of CHSH games as proposed by Reichardt et al.

Controlling polar molecules in optical lattices
TL;DR: In this article, the authors theoretically investigate the interaction of polar molecules with optical lattices and microwave fields and demonstrate the existence of frequency windows in the optical domain where the complex internal structure of the molecule does not influence the trapping potential of the lattice.

Entanglement of superposition of multi-states
Song-Song Li,Yi-Bin Huang +1 more
TL;DR: In this article, the entanglement of superposition of multi-state states is investigated in three cases when the states in the superposition are mutually biorthogonal, mutually orthogonal and non-orthogonal.

Coherence and multimode correlations from vacuum fluctuations in a microwave superconducting cavity
TL;DR: In this article, double parametric pumping of a superconducting microwave cavity was shown to generate another type of correlation, namely coherence between photons in separate frequency modes, which is tunable by the phases of the pumps and are established by a quantum fluctuation that stimulates the simultaneous creation of two photon pairs.

Elementary gates for quantum computation.

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.

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.
