Useful quantum networks are hobbled by the problem of decoherence from environmental "noise." But a new breakthrough could ...

By integrating ultrafast lasers into quantum computing, they have tackled two long-standing challenges that have impeded progress for more than two decades: decoherence and speed. Decoherence ...

Quantum teleportation, once a staple of sci-fi lore, is now edging closer to scientific fact. What seemed impossible a decade ...

Qudit-based quantum systems could store more information and perform computations more efficiently than qubit-based systems, ...

Or Katz from Cornell University. Spin decoherence, the process by which quantum spin information is lost due to environmental interactions, is a key obstacle in the development of quantum ...

The qubit gradually changes to classical behavior. However, purposeful quantum measurement forces a clean 0/1 result, whereas decoherence degrades the qubit. See quantum computing. THIS DEFINITION ...

A quantum state of light was successfully teleported through more than 30 kilometers (around 18 miles) of fiber optic cable amid a torrent of internet traffic – a feat of engineering once considered ...
