Quantum communicator

A quantum communicator was an advanced communication device.

It allowed communication with quantum-locked beings such as Weeping Angels. One such communicator was acquired by one incarnation of the Meddling Monk, who used it to represent the Time Lords in talks with the Weeping Angel population of New York City in the 1970s. (AUDIO: The Side of the Angels)

In 2019, Director Giles was given a "bootleg" quantum communicator by "a friend", and placed it on the Dr Smith shelf in P.R.O.B.E. HQ, carefully wrapped inside a newspaper. (PROSE: Out of the Box)
