Model-Checking Linear-Time Properties of Quantum Systems
Mingsheng Ying, Yangjia Li, Nengkun Yu +1
We define a formal framework for reasoning about linear-time properties of quantum systems in which quantum automata are employed in the modeling of systems and certain closed subs…
Analytic control methods for high fidelity unitary operations in a weakly nonlinear oscillator
J. M. Gambetta, F. Motzoi, S. T. Merkel +1
In qubits made from a weakly anharmonic oscillator the leading source of error at short gate times is leakage of population out of the two dimensional Hilbert space that forms the…
Quantum query complexity of minor-closed graph properties
Andrew M. Childs, Robin Kothari
We study the quantum query complexity of minor-closed graph properties, which include such problems as determining whether an -vertex graph is planar, is a forest, or does not c…
Entanglement-Enhanced Classical Communication over a Noisy Classical Channel
R. Prevedel, Y. Lu, W. Matthews +2
We present and experimentally demonstrate a communication protocol that employs shared entanglement to reduce errors when sending a bit over a particular noisy classical channel. S…
Beating the channel capacity limit for linear photonic superdense coding
Julio T. Barreiro, Tzu-Chieh Wei, Paul G. Kwiat
Dense coding is arguably the protocol that launched the field of quantum communication. Today, however, more than a decade after its initial experimental realization, the channel c…
Passive sources for the Bennett-Brassard 1984 quantum key distribution protocol with practical signals
Marcos Curty, Xiongfeng Ma, Hoi-Kwong Lo +1
Most experimental realizations of quantum key distribution are based on the Bennett-Brassard 1984 (so-called BB84) protocol. In a typical optical implementation of this scheme, the…
