Data centers are huge, industrial-sized buildings that house hundreds of thousands of servers and related technologies that allow Internet traffic to flow uninterrupted.
Although Google, Facebook, Cisco, Amazon, and a few other large companies are building and maintaining their own data centers and addressing energy issues internally, thousands of other data centers are in use and/or being built that demand enormous amounts of energy both to operate and to cool the ‘farm’ because of the tremendous heat servers generate.
Research indicates that unceasing Internet growth is straining the resources and architectures of existing commercial data centers as well as data centers for government, education, and medical institutions. The Internet of Things (IoT), social media, videos, smart phones, and other Internet-dependent devices are all increasing demand on our current data center and server farm infrastructure. As traffic increases, so does the need for increased energy & speed.
In addition, some routes may seldom be used while others over-used. Over-provisioning also introduces greater energy consumption. Our Holographic Optical Switches remove the need to over-provision.
Data centers require enormous amounts of energy to operate, largely to keep their technology cool. Research published as recently as a June 2016 report by the Lawrence Berkeley National Laboratory for the United States Department of Energy shows that
“In 2014, data centers in the U.S. consumed an estimated 70 billion kWh, representing about 1.8% of total U.S. electricity consumption.” 
Post-Quantum Tek intends to commercialize a unique, top-of-rack technology developed by the University of Arizona’s College of Optical Sciences: a holographic optical switch that is cooler … and faster … than switch technology in use today. This optical switch dramatically reduces energy usage, increases data throughput, and enables increased security options.
