Scientists say they’ve cracked a key challenge in scalable quantum hardware after generating an error-correcting, light-based ...

Here, optical quantum computers really seemed to fall down. An optical quantum computer could be easy to set up and measure, or it could be programmable—but not both.

The race to build the first useful quantum computer is on and may revolutionize the world with brand new capabilities, from ...

Building an optical quantum computer. As already discussed, optical computing could bring us much faster and more power-conscious CPUs in the years to come; however, important as they may be, the ...

Now, optical quantum computers have joined the club with a painstakingly configured device that doesn’t quite manage to demonstrate quantum supremacy. But before we get to the news, let's delve ...

"In 2001, all-optical quantum computing became feasible with the discovery that scalable quantum computing is possible using only single-photon sources, linear optical elements, and single-photon ...

All the latest science news on optical quantum computing from Phys.org. Find the latest news, advancements, and breakthroughs.

Optical fibers fit for the age of quantum computing Date: July 29, 2024 Source: University of Bath Summary: A new generation of specialty optical fibers has been developed by physicists to cope ...

Known as “linear optical quantum computing” (LOQC), it usually involves preparing photons in a specific quantum state and then sending them through a series of optical components, such as beam ...

(One of our labs at NTT Research is focused on a combination of photonics and quantum computing.) Niche Applications As with quantum computers, optical computers are far from "general purpose" status.

While classical computers store and process information as “bits” that can have one of two states – “0” or “1” – a quantum computer exploits the ability of quantum particles to be in “superposition” ...

The usefulness of most quantum computers is still significantly limited by the low number of qubits that hardware can support. But simple fiber optic cables – just like the ones used for ...
