Quantum Science & Technology

Quantum physics is the study of the smallest particles which are likely to be the fundamental particles of universe. Quantum physics is necessary to understand the properties of solids, atoms, nuclei, sub nuclear particles and light. Its Subfields include: Quantum computing, Quantum cryptography, Quantum teleportation. Quantum cryptography the science of sending secret messages through a quantum channel. It uses properties of quantum mechanics to establish a secure key, a method known as quantum key distribution. Quantum computers boost processing power as they use quantum bits, or qubits. The most accurate clocks in the world, atomic clocks, use principles of quantum theory to measure time. Quantum techniques can also be useful to reducing the noise present in laser beams, a method known as squeezing.
