Rishabh Rikhiram Sharma, a sitarist and music producer from the Rikhi Ram lineage of instrument makers, has a separate fan base among music lovers. From being the first sitarist to perform solo at the White House to advocating music as a therapeutic tool for emotional well-being, the musician carries forward a culturally rich classical tradition. He has, however, often called himself the last and youngest disciple of Pandit Ravi Shankar – a claim recently opposed by the legendary musician's daughter, Anoushka Shankar. Rishabh Rikhiram Sharma has often revealed in past interviews how a conversation with Pandit Ravi Shankar marked a turning point in his musical journey. Nullifying his claims, however, Anoushka Shankar mentioned that he was never formally a disciple of her father. “Rishab is really talented, and he is clearly speaking to people in a really wonderful way. I think there is some misunderstanding about his guruship,” Anoushka told Humans Of Bombay . Although Anoushka pr...
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.
