Strengthened quantum Hamming bound
Sixia Yu, C. H. Lai, C. H. Oh
We report two analytical bounds for quantum error-correcting codes that do not have preexisting classical counterparts. Firstly the quantum Hamming and Singleton bounds are combine…
Nonadditive quantum error-correcting code
Sixia Yu, Qing Chen, C. H. Lai +1
We report the first nonadditive quantum error-correcting code, namely, a code which is a 12-dimensional subspace within a 9-qubit Hilbert space, that outperforms the o…
Controllable Quantum Switchboard
D. Kaszlikowski, L. C. Kwek, C. H. Lai +1
All quantum information processes inevitably requires the explicit state preparation of an entangled state. Here we present the construction of a quantum switchboard which can act…
Manipulating Quantum States of Molecules Created via Photoassociation of Bose-Einstein Condensates
Xiao-Ting Zhou, Xiong-Jun Liu, Hui Jing +2
We show the quantum state transfer technique in two-color photoassociation (PA) of a Bose-Einstein condensate, where a quantized field is used to couple the free-bound transition f…
General formalism of Hamiltonians for realizing a prescribed evolution of a qubit
D. M. Tong, Jing-Ling Chen, L. C. Kwek +2
We investigate the inverse problem concerning the evolution of a qubit system, specifically we consider how one can establish the Hamiltonians that account for the evolution of a q…
Experimental Quantum Cloning with Prior Partial Information
Jiangfeng Du, Thomas Durt, Ping Zou +5
When prior partial information about a state to be cloned is available, it can be cloned with a fidelity higher than that of universal quantum cloning. We experimentally verify thi…
