Here’s the deal: Quantum Computers are(potentially) the next big thing in processing power and something really big happened. Essentially, now they have potential for a new bus or a way to transfer data at the speed of light.

This is oversimplified, but quantum computers rather than using binary bits, use superposition to store more information as quantum states till they are retrieved or qubits. Although it might not seem ideal while gaming or regular desktop use, in datacenters it’s a whole different story. What to years before can now be done in days making our life much easier.


Scientists from NUST MISIS managed to get light to interact meaning, they can now use photons to store data and can literally retrieve it at light speed.


Lot’s of scientists have proposed the idea of using photons(the particles making up light) in quantum computers, but none have succeeded up till now. The problem arises with the fact that photons don’t interact very much with each other, so it’s very hard to encode data into them.


The team at NUST MSIS has overcome these barriers by using superconducting qubits which are in a form of qubit. Using these, we can create an active link between many different quantum computers.


Linking different units allowed us to surpass previous limitations due to the amount of cooling required to keep superconducting qubits operational at their required milliKelvin temperatures. The largest computers so far could only have about a 100 of these superconducting qubits.


It’s Effects


This discovery allows us to transfer data t light speed and also paves the way for a potential new form of quantum storage, specially for quantum computers, pushing us a little ahead towards the goal.
