Overview:

A team of Stony Brook University physicists and their collaborators have taken a significant step toward the building of a quantum internet testbed by demonstrating a foundational quantum network measurement that employs room-temperature quantum memories.

About Quantum Internet

  • It is a theorized and much sought-after network of interconnected quantum computers that will allow people to send, compute, and receive information using quantum technology.
  • A quantum internet would be a network of quantum computers, sensors, and communication devices that will create, process, and transmit quantum states and entanglement.
  • It is anticipated to enhance society's internet system and provide certain services and securities that the current internet does not have.
  • The purpose of the quantum internet is not to replace the internet we know today, but to instead create a co-existent network that can be used to solve specific types of problems.
  • Working
    • Quantum computers use fundamental units of information similar to the bits used in classical computing. These are called “qubits.”
    • However, unlike conventional computer bits—which convey information as a 0 or 1—qubits convey information through a combination of quantum states, which are unique conditions found only on the subatomic scale.
    • Qubits are not either 0 or 1, but rather both and neither, in a quantum phenomenon called superposition.

Q1) What is Quantum mechanics?

It is a subfield of physics that describes the behavior of particles — atoms, electrons, photons and almost everything in the molecular and submolecular realm. Developed during the first half of the 20th century, the results of quantum mechanics are often extremely strange and counterintuitive.
