Observing Brownian motion in vibration-fluidized granular matter
G. D'Anna, P. Mayor, A. Barrat +2
At the beginning of last century, Gerlach and Lehrer observed the rotational Brownian motion of a very fine wire immersed in an equilibrium environment, a gas. This simple experime…
Fast two-bit operations in inductively coupled flux qubits
J. Q. You, Y. Nakamura, Franco Nori
A central problem for implementing efficient quantum computing is how to realize fast operations (both one- and two-bit ones). However, this is difficult to achieve for a collectio…
Engineering quantum pure states of a trapped cold ion beyond the Lamb-Dicke limit
L. F. Wei, Yu-xi Liu, Franco Nori
Based on the conditional quantum dynamics of laser-ion interaction, we propose an efficient theoretical scheme to deterministically generate quantum pure states of a single trapped…
Scalable quantum computing with Josephson charge qubits
J. Q. You, J. S. Tsai, Franco Nori
A goal of quantum information technology is to control the quantum state of a system, including its preparation, manipulation, and measurement. However, scalability to many qubits…
Quantum computing with many superconducting qubits
J. Q. You, J. S. Tsai, Franco Nori
Two of the major obstacles to achieve quantum computing (QC) are (i) scalability to many qubits and (ii) controlled connectivity between any selected qubits. Using Josephson charge…
Controllable manipulation and entanglement of macroscopic quantum states in coupled charge qubits
J. Q. You, J. S. Tsai, Franco Nori
We present an experimentally implementable method to couple Josephson charge qubits and to generate and detect macroscopic entangled states. A large-junction superconducting quantu…
Quantum information processing with superconducting qubits in a microwave field
J. Q. You, Franco Nori
We investigate the quantum dynamics of a Cooper-pair box with a superconducting loop in the presence of a nonclassical microwave field. We demonstrate the existence of Rabi oscilla…
Effects of dynamical phases in Shor's factoring algorithm with operational delays
L. F. Wei, Xiao Li, Xuedong Hu +1
Ideal quantum algorithms usually assume that quantum computing is performed continuously by a sequence of unitary transformations. However, there always exist idle finite time inte…
Quantum phase estimation algorithms with delays: effects of dynamical phases
L. F. Wei, Franco Nori
The unavoidable finite time intervals between the sequential operations needed for performing practical quantum computing can degrade the performance of quantum computers. During t…
