Quantitative complementarity between local and nonlocal character of quantum states in a three-qubit system
Xinhua Peng, Jingfu Zhang, Jiangfeng Du +1
Local or nonlocal character of quantum states can be quantified and is subject to various bounds that can be formulated as complementarity relations. Here, we investigate the local…
Quantum simulation of a system with competing two- and three-body interactions
Xinhua Peng, Jingfu Zhang, Jiangfeng Du +1
Quantum phase transitions occur at zero temperature, when the ground state of a Hamiltonian undergoes a qualitative change as a function of a control parameter. We consider a parti…
A Quantum Adiabatic Algorithm for Factorization and Its Experimental Implementation
Xinhua Peng, Zeyang Liao, Nanyang Xu +4
We propose an adiabatic quantum algorithm capable of factorizing numbers, using fewer qubits than Shor's algorithm. We implement the algorithm in an NMR quantum information process…
Generalization of short coherent control pulses: extension to arbitrary rotations
S. Pasini, G. S. Uhrig
We generalize the problem of the coherent control of small quantum systems to the case where the quantum bit (qubit) is subject to a fully general rotation. Following the ideas dev…
Measuring complete quantum states with a single observable
Xinhua Peng, Jiangfeng Du, Dieter Suter
Experimental determination of an unknown quantum state usually requires several incompatible measurements. However, it is also possible to determine the full quantum state from a s…
NMR implementation of Factoring Large Numbers with GaußSums: Suppression of Ghost Factors
Xinhua Peng, Dieter Suter
Finding the factors of an integer can be achieved by various experimental techniques, based on an algorithm developed by Schleich et al., which uses specific properties of Gaußsums…
