Described herein are various technologies pertaining to detecting tampering of a seal based upon quantum optical communication via a communications channel comprising the seal. A plurality of pulses of light encoded with random data are transmitted on the communications channel, whereupon they are received and their data values measured. The measured data values of the pulses are then compared to the known transmitted data to determine a correlation statistic between the transmitted and received data values. Tampering with the seal can be detected based upon identifying that the correlation statistic has dropped below a threshold non-tampered level of correlation between transmitted and received values.

Secure fiber optic seals enabled by quantum optical communication concepts

A multi-mode showerhead has a housing with a front and a back and an offset integrated water filter system incorporated into the showerhead so that the showerhead with the integrated water filter system may be easily mounted to a normal shower arm without the need of special tools. A water filter cartridge is easily added to or removed from a hollow filter chamber formed in the showerhead by the removal of a front facing filter chamber cap. A multi-mode switch thatselectively changes the spray pattern is mounted on the front between the water filter system and a plurality of nozzles. The entire showerhead and integrated offset water filter system is mounted on a shower arm by means of a swivel joint forming an inlet on the back of the housing and fluidly connected to the hollow filter chamber.
