Experimental demonstration of coherent superpositions in an ultrasonic pseudospin.

We experimentally demonstrate the existence and control of coherent superpositions of elastic states in the direction of propagation of an ultrasonic pseudospin i.e., a φ-bit.

Redetermination of junitoite, CaZn(2)Si(2)O(7)·H(2)O.

The crystal structure of the mineral junitoite, ideally CaZn(2)Si(2)O(7)·H(2)O (calcium dizinc disilicate monohydrate), was first determined by Hamilton & Finney [Mineral. Mag. (1985), 49, 91-95] based on the space group Ama2, yielding a reliability factor R of 0.
