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. Entanglement links …

With the age of quantum computing drawing ever-closer, traditional encryption methods are at risk. While brute force attacks can take months to break through security, quantum attacks can use more advanced techniques to break standard public key cryptography in a much shorter timeframe. Quantum cryptography is an emerging technology …
Read More »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., …
