- Scientific reports
- 8 August 2013

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 special… Expand

Efficient many-party controlled teleportation of multiqubit quantum information via entanglement

- C. Yang, Shih-I Chu, S. Han
- Physics
- 19 February 2004

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 be… Expand

- 14 June 2001

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 electrostatic… Expand

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 the… Expand

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, forming… Expand

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 two… Expand

Simplified realization of two-qubit quantum phase gate with four-level systems in cavity QED

- C. Yang, Shih-I Chu, S. Han
- Physics
- 14 October 2004

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 each… Expand

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 represent… Expand

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

- C. Yang
- Physics
- 25 February 2008

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 to… Expand
