A brand new writer in the fields, Fatima has been taken under my electric spark's RGB- rich and ensures she doesn't engage in excessive snark on the website. It's unclear what command and Conquer are; however, she can talk for hours about the odd rhythm games, hardware, product reviews, and MMOs that were popular in the 2000s. Fatima has been creating various announcements, previews, and other content while here, but particularly enjoys writing regarding Products' latest news in the market she's currently addicted to. She is likely talking to an additional blogger with her current obsession right now.

Researchers at Max Planck Institute Max Planck Institute have developed an efficient method to control the quantum entanglement between photons. They demonstrated it by entangling an unprecedented number of photons. This technique could prove to be an advantage for quantum computers.

Quantum Entanglement is an occurrence that seems like it’s not possible. In essence, particles can be so interconnected that they cannot be considered distinct or separately. Changing a characteristic of one particle can immediately trigger an alteration in the entangled counterpart regardless of how distant they might be. What this means puzzled even Einstein, who famously described the phenomenon in terms of “spooky action at a distance.”

Although it’s not as apparent as it might seem, quantum entanglement has been experimentally proven for a long time. It is even the basis for new technological advancements like quantum computers, in which particles entangled in a network can be utilized to create quantum bits (qubits) that store and process data.

For the best results to be efficient, massive particles must be made and entangled; however, this can be difficult to achieve. This is why, for the latest study that the Max Planck researchers investigated a more reliable method for quantum entanglement. They used it to tie 14 photons successfully – – the biggest group of photons to be entangled.

The team’s experimental setup comprised an optical cavity containing only one rubidium atom.

The research team began with a single atom of rubidium trapped in an optical cavern that bounces electromagnetic waves in specific patterns. A laser hits the particle at a particular frequency, which causes the fraction for specific properties. A second control pulse is aimed at it that causes the atom’s energy to be released as the photon, which is then in a relationship with the atom.

The process repeats by rotating the atom between every photon emission until a complete chain of photons is created that are all interconnected. This process is more efficient than the current techniques and produces more than 43 per cent of the time, about one photon, the two light pulses.

Suppose you’ve been keeping track of quantum records for some time. In that case, 14 particles entangled in a web may not seem like an amount – but scientists have connected hundreds of billions of electrons inside a gas during earlier tests. However, we won’t be capable of harnessing this kind of system to use quantum computers or quantum communications. Photons are far easier to make and utilize in our everyday lives, and the efficacy of this innovative technique is likely to be easy to increase the amount of photon production.

In this regard, the team suggests it is the next stage to test with at least two sources of atoms.

The study is published in Nature.
