Secret parameters in quantum bit commitment
Chi-Yee Cheung
The no-go theorem of unconditionally secure quantum bit commitment depends crucially on the assumption that Alice knows in detail all the probability distributions generated by Bob…

Controlled Quantum Secret Sharing
Chi-Yee Cheung
We present a new protocol in which a secret multiqubit quantum state is shared by players and controllers, where is the encoding state of a quantum secret s…

Distributing a multiparticle state by entanglement swapping
Chi-Yee Cheung
Using entanglement swapping, we construct a scheme to distribute an arbitrary multiparticle state to remote receivers. Only Bell states and two-qubit collective measurements are re…
