A scientist working for the U.S. Navy has filed for a patent on a room-temperature superconductor, representing a potential paradigm shift in energy transmission and computer systems.

Salvatore Cezar Pais is listed as the inventor on the Navy's patent applicationmade public by the U.S. Patent and Trademark Office on Thursday.
The application claims that a room-temperature superconductor can be built using a wire with an insulator core and an aluminum PZT (lead zirconate titanate) coating deposited by vacuum evaporation with a thickness of the London penetration depth and polarized after deposition.
An  is circumferentially positioned around the coating such that when the coil is activated with a pulsed current, a non-linear vibration is induced, enabling room temperature superconductivity.
"This concept enables the transmission of electrical power without any losses and exhibits optimal thermal management (no )," according to the patent document, "which leads to the design and development of novel energy generation and harvesting devices with enormous benefits to civilization."
No data was included in the patent documents.
A room-temperature superconductor is a material that is capable of exhibiting superconductivity at temperatures around 77 degrees Fahrenheit.
Current superconductors work when cooled near absolute zero, and the warmest superconductor, hydrogen sulfide, works at -95 degrees Fahrenheit.
Others have claimed to have invented a room-temperature superconductor in the past. Last year, two Indian scientists claimed to have made a room-temperature superconductor using particles of gold and silver. Other physicists are using pressurized lanthanum and hydrogen.

Why Quantum Computing's Time Is Now

...

There are dozens of textbooks that cover an introduction of this topic. Michael Nielsen and Isaac Chuang authored Quantum Computation and Quantum Information back in 2000, which has been updated and is now in its third printing. This text has been used for both graduate and undergraduate courses.

Universities such as MIT, Caltech, Berkeley and UT Austin all have graduate and undergraduate courses specifically on quantum computing. While one can search to find locations where it is taught, it is not yet mainstream in computer science curricula. When it is offered, it is often as a special topics course. However, this is changing.

MIT x-Pro offers an excellent online introductory course to quantum computing taught by MIT quantum professors Isaac Chuang, Aram Harrow, William Oliver and Peter Shor.

Krysta Svore, leads the Quantum – Redmond (QuArC) group at Microsoft Research. She also teaches an undergraduate course entitled “Intro to Quantum Computing” at nearby University of Washington. She shared with me this week that she even has freshmen successfully taking the course.

The NQIA authorizes $1.2 billion over five years for federal activities to increase investment in quantum information science, and specifically supporting the development of a quantum-smart workforce. The law also establishes a National Quantum Coordination Office and creates an advisory committee to advise the White House on quantum computing.
