Scientists take a step closer to creating light swords

Scientists have found a way to bind photons of light that can produce fixed and fixed light.

Scientists are about to build lightsaber light swords

The dream of many people wanting to become a Jedi Knight holding a lightaber stick may not be far away, as scientists have found a way to condense photon light to form a certain shape.

Photons are massless particles and they move at very fast speeds, forming light rays. It is also therefore that light rays always follow straight lines to the end and cannot be limited and create a certain shape.

But the new discovery by NIST Institute scientists and the University of Maryland may change that. This new finding is based on previous research in 2013, when scientists found a way to attach a photon to the top of another photon.

The lightsaber light sword is a limited and shaped high-energy light.

From that study, scientists changed some conditions to link these photons together and bind them to a certain distance limit in the charge environment. No matter how far they move, this link is not broken and the distance between them remains the same.

Theoretically, it is like a link between two hydrogen atoms in a hydrogen molecule . Researcher Alexey Gorshkov from NIST said: 'This is the first time we have found a way to bind two photons at a fixed distance. This finding promises to build more complex objects based on photons of light '.

And if we can shape the light, the future of a lightsaber sword won't be too far away. Although scientists believe that creating a compact handheld device capable of shaping such light is very difficult.

Currently, only under conditions and in laboratory devices can ensure the alignment between photons is fixed. And the adjustment process with these devices is extremely complicated.

By using a charge environment, scientists can link photons together.

However, according to scientists, the application of this new discovery is also extremely important. For example, if engineers need to correctly determine the size of the light sensors, scientists can provide a standard template with the exact number of photons they want.

More importantly, linking photons will open up prospects for photon-based information processors. It not only creates a completely new computer technology platform, but also significantly saves energy.

Previously, light signals transmitted by optical fiber would have to go through a system that converted into electrical signals. This process causes loss and huge power consumption. If data transmission and information processing can be carried out directly on photons, it can increase processing efficiency and reduce power consumption.

Gorshkov added: ' Previously, photons had no mass and moved at the speed of light. So if we can link these photons and slow them down, we can detect things that we never knew about them before. '

Why can't lightsaber become a reality?
