A collaboration between McMaster and Harvard researchers has generated a new platform in which light beams communicate with one another through solid matter, establishing the foundation to explore a new form of computing.

Their work is described in a paper published today in the Proceedings of the National Academy of Sciences.

Kalaichelvi Saravanamuttu, an associate professor of Chemistry and Chemical Biology at McMaster, explains that the technology brings together a form of hyrdrogel developed by the Harvard team with light manipulation and measurement techniques performed in her lab, which specializes in the chemistry of materials that respond to light.

Overall, India’s science ministry, which oversees the department of science and technology; biotechnology; and scientific and industrial research, received 144 billion rupees in the 2020–21 budget, a 10.8% increase over promised funds in the 2019–20 budget.

Latest budget includes more than a billion dollars in funding for quantum computing, communications and cryptography.

Most modern electronic devices rely on tiny, finely-tuned electrical currents to process and store information. These currents dictate how fast our computers run, how regularly our pacemakers tick and how securely our money is stored in the bank.

In a study published in Nature Physics, researchers at the University of British Columbia have demonstrated an entirely new way to precisely control such electrical currents by leveraging the interaction between an electron’s spin (which is the quantum magnetic field it inherently carries) and its orbital rotation around the nucleus.

“We have found a new way to switch the electrical conduction in materials from on to off,” said lead author Berend Zwartsenberg, a Ph.D. student at UBC’s Stewart Blusson Quantum Matter Institute (SBQMI). “Not only does this exciting result extend our understanding of how electrical conduction works, it will help us further explore known properties such as conductivity, magnetism and superconductivity, and discover new ones that could be important for quantum computing, data storage and energy applications.”

What our senses allow us to experience may not reflect what actually exists. It may be a creation of our own consciousness, or a computer simulation designed by superintelligent beings.

Still baffled by quantum computing? How about turning to comic books (graphic novels for the well-read among you) for some clarity and a little humor on QC. The National Science Foundation has done just as part of its EPiQC (Enabling Practical-scale Quantum Computing) program. So far eight €˜Zines €™ have been created with more to come.

€œComic books offer approachable ways to convey both humor and information. One might think that comic books would not be able to convey complex information like the ideas behind QC. In this case, one would be wrong, at least for one as creative as the University of Chicago €™s Diana Franklin, as part of the National Science Foundation (NSF) funded https://www.epiqc.cs.uchicago.edu/”>EPIQC Expedition in Computing, € wrote Mark Hill of the University of Wisconsin-Madison in a recent blog for Computing Community Consortium, run by NSF.

€œIn particular, Diana and colleagues have developed eight, with more coming, €œ https://www.epiqc.cs.uchicago.edu/zines”>zines € that are comic-book-like pamphlets obtained by printing and folding a single sheet of paper. The topics include quantum notation, superposition, and history. In my humble opinion, these are great examples of the synergy possible with research and education done together. Enjoy! €.
