(a) Schematic of non-local mode selection by metasurface-integrated quantum analog operation. F^1, F^2, F^3, and F^4 are the differential operators. The green area has been designed to construct ...

Scientists in the Riccio College of Engineering at the University of Massachusetts Amherst and the University of California Santa Barbara have demonstrated key laser and ion trap components necessary ...

Light-based quantum technologies, such as quantum communication and photonic quantum computing, require reliable sources of individual photons and, ideally, pairs of entangled photons. Semiconductor ...

In an ongoing effort to bring quantum science out of the tightly controlled lab environment and into the field, researchers from UC Santa Barbara and the University of Massachusetts Amherst have, for ...

Researchers recently connected their campuses with an experimental quantum communications network using two optical fibers. Researchers at the University of Rochester and Rochester Institute of ...

As quantum computers continue to advance, many of today’s encryption systems face the risk of becoming obsolete. A powerful alternative—quantum cryptography—offers security based on the laws of ...

A new microchip-sized device could dramatically accelerate the future of quantum computing. It controls laser frequencies with extreme precision while using far less power than today’s bulky systems.

Slight temperature changes, imperceptible manufacturing imperfections, and heat generated by their own components can completely ruin an entire quantum quantum system-on-chip. Silicon photonics could ...

In 1925, German physicist Werner Heisenberg published a paper on quantum mechanics, upending classical physics and launching the world into the quantum age. Now, 100 years later, researchers across ...

The German consortium QuINSiDa has achieved a major step toward mobile quantum-secure communication. They demonstrated a ...
