New Materials enabling Quantum repeaters and modems, a key technology for extremely secure large scale Quantum Internet

The first quantum revolution brought about semiconductor electronics, the laser and finally the internet. The coming, second quantum revolution promises spy-proof communication, extremely precise quantum sensors and quantum computers for previously unsolvable computing tasks.   Quantum secure communication relies on sharing of entangled states between parties. Over short distances (less …

Continuing interest of Space agencies and Militaries to exploit Zero-Point Energy for applications like propulsion and for generating electric power.

Zero-point energy is the energy that remains when all other energy is removed from a system. Zero-point energy  is the lowest energy that a given quantum mechanical system can have (i.e., the ground state of the system). In quantum field theory, it refers to the energy of the vacuum (i.e., …

Graphene Bolometers emerging as high speed and sensitive Quantum photon detectors for quantum computation and quantum communication

Measurement connects the world of quantum phenomena to the world of classical events. It has both a passive role—in observing quantum systems—and an active one, in preparing quantum states and controlling them. In quantum physics, a measurement is the testing or manipulation of a physical system in order to yield …

Quantum Hyper Entanglement is a key enabler for high-capacity quantum communications, teleportation, processing and imaging

The extraordinary promise of quantum technology—depend on quantum “entanglement,” in which the physical states of two or more objects such as atoms, photons or ions become so inextricably connected that the state of one particle can instantly influence the state of the other—no matter how far apart they are. Today, …
