Optical Fiber Breakthrough: Transmitting Quantum and Conventional Data in One Cable - Technology

Scientists have achieved a major breakthrough by successfully transmitting quantum data and conventional data through a single Optical fiber for the first time . The groundbreaking research showcased the ability to send quantum data in the form of entangled photons and traditional internet data as laser pulses over the same fiber - optic cable . This new " hybrid " network could revolutionize the field of quantum communications by allowing both quantum and conventional data to coexist within the same infrastructure.

 Fiber - optic cables are typically made up of thin strands of glass or plastic fibers that transmit data as pulses of infrared light . These cables utilize different color channels to send data , each corresponding to a specific wavelength of light.

The researchers unveiled their findings in a study published on July 26 in the journal Science Advances , highlighting the potential for a more efficient implementation of quantum communications through this innovative approach . While previous research has demonstrated the transmission of quantum data through standard fiber - optic cables , this experiment marks the first time that both quantum and conventional data have been sent simultaneously in the same color channel.

Entanglement , a phenomenon where two qubits are interconnected to share information regardless of their spatial or temporal relationship , is crucial for transmitting quantum data through fiber - optic cables . However , entanglement is easily disrupted by environmental disturbances such as noise or interference from other signals , leading to data loss . To overcome these challenges , scientists employed electro - optic phase modulation to precisely adjust the frequency of laser pulses , ensuring compatibility with the entangled photons ' color . This technique enabled the seamless transmission of both quantum and conventional data in the same color channel without compromising the integrity of the quantum information.

The ability to transmit quantum and conventional data through a single channel not only optimizes the usage of fiber - optic cables but also paves the way for the practical implementation of hybrid networks . By freeing up additional color channels in the fiber - optic cable , more data can be transmitted , enhancing the scalability and applicability of quantum computing and quantum cryptography . The successful integration of the conventional internet with the quantum internet represents a significant milestone in the advancement of quantum technologies . This experiment showcases the promising future of hybrid networks and their potential to revolutionize the field of quantum communications.
