Qubits—the fundamental units of quantum information—drive entire tech sectors. Among them, superconducting qubits could be ...

One of those detections was EP240408a, an unusual blast that lit up discussions between astronomers. Zhang and his colleagues immediately utilized the spacecraft's second instrument, the Follow-up ...

Quantum computing takes a leap forward with fiber-optic-connected qubits, making large-scale and networked quantum systems ...

This consists of an input layer that receives a signal, an optical cavity that acts like a second layer containing feedback loops (or recurrent loops) that can be tweaked to change the device behavior ...

A time lens is one possibility — able to image the temporal profile of a short optical signal, analogous to a conventional lens. Such a device has now been created on a silicon chip. Ultrafast ...

For gamers, some optical switches can provide analog signaling that can be picked up in gaming software as a signal from 0 to 100% based on how far or how fast the key is pressed. See mechanical ...
