Wiring a new path to scalable quantum computing

Last year, Google produced a 53-qubit quantum computer that could perform a specific calculation significantly faster than the world's fastest supercomputer. Like most of today's largest quantum computers, this system boasts ...

Light-emitting silicon for photonic computing

If computers transmitted data using photons instead of electrons, they would perform better and use less power. European researchers are now studying a new light-emitting alloy of silicon and germanium to obtain photonic ...

Broadband enhancement relies on precise tilt

Quantum photonics involves a new type of technology that relies on photons, the elementary particle of light. These photons can potentially carry quantum bits of information over large distances. If the photon source could ...

On-chip single-mode CdS nanowire laser

In recent years, increasing attention has been paid to the integration of active nanowires with on-chip planar waveguides for on-chip light sources. Towards this goal, scientists in China demonstrated a highly compact on-chip ...

What if we could teach photons to behave like electrons?

To develop futuristic technologies like quantum computers, scientists will need to find ways to control photons, the basic particles of light, just as precisely as they can already control electrons, the basic particles in ...

How to verify that quantum chips are computing correctly

In a step toward practical quantum computing, researchers from MIT, Google, and elsewhere have designed a system that can verify when quantum chips have accurately performed complex computations that classical computers can't.

A cavity leads to a strong interaction between light and matter

Researchers have succeeded in creating an efficient quantum-mechanical light-matter interface using a microscopic cavity. Within this cavity, a single photon is emitted and absorbed up to 10 times by an artificial atom. This ...

Quantum photonics by serendipity

A photonic chip with no less than 128 tunable components proves to be a true computing "Swiss army knife" with a variety of applications. During her research on measuring light wavelengths using this photonic chip, Caterina ...

Boosting light-based computing

University of Twente spinoff company QuiX is currently developing a photonic chip using the quantum properties of light for carrying out complex calculations. The new chip, of which a first version is already operational, ...
