Photonics Focus Magazine Vol. 1 Issue 6

November/December 2020 | Vol. 1 | Issue 6

As governments pour money into quantum R&D, Photonics Focus explores the ways this burgeoning field intersects with people working in optics and photonics. Light-based methods of quantum computing offer an alternative approach to the better-known approaches pursued by Google and IBM; we take a deep dive into quantum encryption to find out whether our information can ever really be secure; and we explore a fundamental question surrounding a most fundamental particle by asking "what, exactly, is a photon?"

Select articles are available online, but the complete issue is available for download as a PDF.

Quantum encryption makes headway in the quest to keep our secrets secure
Hacking the unhackable
So far, quantum computing has been ruled by ions and electrons, but does its future lie with photons?
A new kind of quantum
With new experiments and technologies, physicists have shown they can control individual photons with unprecedented precision. But the enigmatic elementary particle still hides its true colors.
What, exactly, is a photon?
