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…
Quantum Bit Commitment can be Unconditionally Secure
Chi-Yee Cheung
It is generally believed that unconditionally secure quantum bit commitment (QBC) is proven impossible by a "no-go theorem". We point out that the theorem only establishes the exis…
