Query: An optical implementation of quantum bit commitment using
  infinite-dimensional systems   Unconditionally secure quantum bit commitment (QBC) was widely believed to be
impossible for more than two decades. But recently, basing on an anomalous
behavior found in quantum steering, we proposed a QBC protocol which can be
unconditionally secure in principle. The protocol requires the use of
infinite-dimensional systems, thus it may seem less feasible at first glance.
Here we show that such infinite-dimensional systems can be implemented with
quantum optical methods, and propose an experimental scheme using Mach-Zehnder
interferometer.
