Fast and simple scheme for generating NOON states of photons in circuit QED
The generation, manipulation and fundamental understanding of entanglement lies at very heart of quantum mechanics. Among various types of entangled states, the NOON states are a kind of specialExpand

Efficient many-party controlled teleportation of multiqubit quantum information via entanglement
We present a way to teleport multiqubit quantum information from a sender to a distant receiver via the control of many agents in a network. We show that the original state of each qubit can beExpand

Structure and Dynamics of Calcium-activated Calmodulin in Solution
Abstract Two 4-ns molecular dynamics simulations of calcium loaded calmodulin in solution have been performed, using both standard nonbonded cutoffs and Ewald summation to treat electrostaticExpand

10-Qubit Entanglement and Parallel Logic Operations with a Superconducting Circuit.
Here we report on the production and tomography of genuinely entangled Greenberger-Horne-Zeilinger states with up to ten qubits connecting to a bus resonator in a superconducting circuit, where theExpand

Phase gate of one qubit simultaneously controlling n qubits in a cavity or coupled to a resonator
We propose how to realize a three-step controlled-phase gate of one qubit simultaneously controlling n qubits in a cavity or coupled to a resonator. The n two-qubit controlled-phase gates, formingExpand

n-qubit-controlled phase gate with superconducting quantum-interference devices coupled to a resonator
We present a way to realize an n-qubit controlled phase gate with superconducting quantum-interference devices (SQUIDs) by coupling them to a superconducting resonator. In this proposal, the twoExpand

Simplified realization of two-qubit quantum phase gate with four-level systems in cavity QED
We propose a method for realizing two-qubit quantum phase gate with 4-level systems in cavity QED. In this proposal, the two logical states of a qubit are represented by the two lowest levels of eachExpand

Realization of an n -qubit controlled- U gate with superconducting quantum interference devices or atoms in cavity QED
We propose an approach to realize an n-qubit controlled-U gate with superconducting quantum interference devices (SQUIDs) in cavity QED. In this approach, the two lowest levels of a SQUID representExpand

Comparison of the sensitivity to systematic errors between nonadiabatic non-Abelian geometric gates and their dynamical counterparts
We investigate the effects of systematic errors of the control parameters on single-qubit gates based on nonadiabatic non-Abelian geometric holonomies and those relying on purely dynamical evolution.Expand

A new protocol for constructing nonlocal n-qubit controlled-U gates
We present a new protocol for constructing a nonlocal n-qubit controlled-U gate. In this protocol, no prior sharing of entanglement is needed and only one ancilla qubit is sent once from one party toExpand
