Quantum Teleportation Now Possible Over Everyday Internet Cable

In a groundbreaking scientific achievement, researchers have figured out a way to achieve the unthinkable: quantum teleportation. While the name may suggest that humans could be teleported through the technology, it is far from the real-life implication of the technology. Quantum teleportation allows the transfer of information instantly and over any distance without needing any future technology. Led by Prem Kumar from Northwestern University, Illinois, US, scientists demonstrated quantum teleportation over standard fibre optic cable that already carries everyday internet traffic, according to a report in ScieneAlert.

In simple terms, quantum teleportation involves sending information from one place to another using something called "quantum entanglement". Think of entanglement like an invisible twin connection where two particles, even if miles apart, are linked in a way that what happens to one instantly affects the other. Unlike sending a physical object, you are sending the state or condition of a particle.

"This is incredibly exciting because nobody thought it was possible. Our work shows a path towards next-generation quantum and classical networks sharing a unified fibre optic infrastructure. Basically, it opens the door to pushing quantum communications to the next level," said Mr Kumar.

The study involved the careful management of light scattering to ensure that the delicate quantum information, carried by photons, could survive amidst the swarm of internet data. To achieve the desired result, the scientists utilised a specific wavelength for the quantum signal and implemented filters to minimise interference from other data streams.

"We carefully studied how light is scattered and placed our photons at a judicial point where that scattering mechanism is minimised. We found we could perform quantum communication without interference from the classical channels that are simultaneously present," added Mr Kumar.

The result was a successful teleportation of a quantum state of light, which represents a significant leap towards integrating quantum communication with existing internet infrastructure. Notably, this was not just a simulation; it was done in real-world conditions, showcasing the practical viability of quantum communication alongside traditional data transmission.

One of the biggest appeals of quantum teleportation is that it can occur almost as fast as light travels. The development is a big step towards quantum internet that could revolutionise traditional computing. From secure encryption methods to enhanced sensing capabilities to potentially even connecting quantum computers on a global scale, without needing specialised infrastructure -- the potential for the technology remains immense.

PM Modi To Reschedule 3-Nation Europe Visit As Tensions With Pakistan Soar

Prime Minister Narendra Modi has put his three-nation Europe visit on hold as tensions between India and Pakistan have surged in the wake of the terror attack in Jammu and Kashmir's Pahalgam in which 26 civilians were killed by Pak-linked terrorists in a religiously-motivated terror attack. India responded on Wednesday with precision missile strikes on terror camps in Pakistan and Pakistan-occupied Kashmir. PM Modi, who is closely-monitoring the situation, has reportedly asked for his visit to Croatia, Norway, and the Netherlands, which was due next week, to be rescheduled. As per his original schedule Prime Minister Modi was to commence his official visit to the three nations on May 13. He was also going to participate in the India-Nordic Summit in Oslo on May 15 and 16. All three countries have been informed about the change in PM Modi's schedule. They have also been appraised about the current situation between India and Pakistan. Last month too, on the day of the Pahalga...

Delhi to Get More EV Charging, Battery Swapping Stations as Cab Aggregators Increase E-Bikes

The NDMC is planning to increase the number of EV charging stations in Lutyens' Delhi and even provide battery swapping facilities at some of these points, a senior official said on Wednesday. With Delhi being among the most polluted capitals in the world, the New Delhi Municipal Council (NDMC) has been making a push for electric vehicles to nudge residents to opt for cleaner vehicle options. There are around 100 electric vehicle (EV) charging stations across the national capital at present and this would be the first time that some of them would have battery swapping facilities, which is quite prominent in Western countries, he said. The official said the aim is to provide easy accessibility to charging stations and to save time by providing swapping facilities. This will give a major push to EVs in the city. Various PSUs, including the Rajasthan Electronics and Instruments Limited (REIL) and the Kerala State Electronics Development Corporation Limited (KELTRON), have approac...

After Nitish Kumar's 'Praise', BJP Says Doors Closed For Him

The opposition BJP in Bihar on Thursday said that its doors were "closed" for Chief Minister Nitish Kumar who dumped the saffron party a year ago, stripping it of power in the state. State BJP President Samrat Choudhary made the averment to this effect in reply to queries from journalists about the Janata Dal United leader's address to the convocation ceremony of Mahatma Gandhi Central University at Motihari. Speaking in the presence of President Droupadi Murmu and Governor Rajendra Arlekar, Mr Kumar had freely spoken of the tussle he had with the then Congress government at the Centre for getting a university approved for Motihari, where Mahatma Gandhi had launched the Champaran Satyagraha. Without mentioning Prime Minister Narendra Modi by name, Mr Kumar acknowledged that the project saw the light of the day only after a change of guard "in 2014" as the UPA government "initially refused and after much persuasion agreed in principle but did not move for...
