That would be the Quantum logic clock.

The most important gate is probably the CNOT gate, because combined with qubit superpositions and measurements, it forms the basis of a universal quantum computer. A quantum computer uses CNOT gates instead of conventional logic gates (such as NAND) because quantum mechanics requires that quantum computations be reversible.

• Quantum applied science is a young discipline of physics and technology, which transitions, some of the stranger characteristics of quantum mechanics, especially quantum entanglement and most recently quantum tunneling, into virtual applications such as quantum computing, quantum coding, quantum simulation, quantum metrology, quantum sensing, and quantum imaging.

In the universe energy, matter and go as per quantum. Energy is released in quantum of photon. Electron has a quantum mass. Proton has quantum mass. Both has a quantum charge. Neutron has a quantum mass. Speed of light is a quantum. Big bang is a quantum event essentially occurring at particular mass. It takes a quantum energy for shifting of electrons from one shell to other. In photo-luminescence light energy is released in quantum.
