Generating coherent states of entangled spins

Author(s) : Yu, H , Luo, Y , Yao, W
Description : A coherent state of many spins contains quantum entanglement, which increases with the decrease of the collective spin value. We present a scheme to engineer this class of pure state based on incoherent spin pumping with several collective raising and lowering operators. In a pumping scenario aimed ...

Deterministic preparation of Dicke states of donor nuclear spins in silicon

Author(s) : Luo, Y , Yu, H , Yao, W
Description : We present a scheme to deterministically prepare various symmetric and asymmetric Dicke states for donor nuclear spins in silicon. The state preparation is realized by cooperative pumping of nuclear spins by coupled donor electrons, and the required controls are in situ to the prototype Kane's archi...

Cross-listing and pricing efficiency: the informational and anchoring role played by the reference price

Author(s) : Chang, EC , Luo, Y , Ren, JJ
Description : We propose that when a firm cross-lists in segmented markets, in pricing the second issued share, the first issued share price as a reference plays both an informational and anchoring role. We develop a model illustrating the dual-role and relating the anchoring bias to the IPO underpricing of the s...

A note on entrepreneurial risk, capital market imperfections, and heterogeneity

Author(s) : Luo, Y , Gong, L , Zou, HF
Description : Empirical evidence shows that entrepreneurs hold a large fraction of wealth, have higher saving rates than workers, and face substantial uninsurable entrepreneurial and investment risks. This paper constructs a heterogeneous-agent general equilibrium model with uninsurable entrepreneurial risk and c...

M-Channel compactly supported biorthogonal cosine-modulated wavelet bases

Author(s) : Chan, SC , Luo, Y , Ho, KL
Description : In this correspondence, we generalize the theory of compactly supported biorthogonal two-channel wavelet bases to M -channel. A sufficient condition for the M-channel perfect reconstruction filter banks to construct M-channel biorthogonal bases of compactly supported wavelets is derived. It is shown...

Theory and design of arbitrary-length biorthogonal cosine-modulated filter banks

Author(s) : Luo, Y , Chan, SC , Ho, KL
Description : The design and generalization of Perfect-reconstruction (PR) cosine-modulated filter banks (CMFB) have been studied extensively due to its low design and implementation complexity. In this paper, the theory and design of arbitrary-length biorthogonal CMFB is considered. This is a generalization of t...

M-channel cosine-modulated wavelet bases

Author(s) : Chan, SC , Luo, Y , Ho, KL
Description : In this paper, we propose a new M-channel wavelet bases called the cosine-modulated wavelets. We first generalize the theory of two-channel biorthogonal compactly supported wavelet bases to the M-channel case. A sufficient condition for the M-channel perfect reconstruction filter banks to construct ...
