We spell out details of a simple argument for a security bound for the secure relativistic quantum bit commitment protocol of Ref. [1].

The impossibility proof on unconditionally secure quantum bit commitment is critically reviewed. Different ways of obtaining secure protocols are indicated.

This paper has been withdrawn by the authors due to some technical problems in the paper.

A quantum protocol for bit commitment the security of which is based on technological limitations on nondemolition measurements and long-term quantum memory is presented.

This paper has been temporarily withdrawn for corrections.

The ``impossibility proof'' on unconditionally secure quantum bit commitment is examined. It is shown that the possibility of juxtaposing quantum and classical randomness has not been properly taken into account. A specific protocol that…
