Quantum Technology will be used in many different parts in your life. Here you will find some examples of Quantum Technology applications and their scientific explanation.
What are big computers doing nowadays and how are they doing it? If you look at the individual processors in a modern supercomputer, sure they are fast and probably more powerful than what you have in your own machine – but not by much and that is not where their power is coming from.
A new generation of quantum enhanced optical clock is now emerging showing significantly improved accuracy with respect to the present atomic clocks. These clocks will further push the possibility to use clocks for sensing of gravitational waves, dark matter detection, earthquake detection, relativistic geodesy, foundations of physics tests, but the clock accuracy should be available outside metrological labs.
Designing new chemical processes and molecules is a crucial driver of human progress. Doing this in the laboratory alone is slow and difficult – would it not be nice to simulate new compounds on the computer?
How the Smartphone electronic circuitry and CCD camera sensors be replaces by technologies based on Quantum Mechanics
Quantum communication encapsulates a vast array or technologies and applications that range from state of the art laboratory experiments to commercial reality. It has some of the most mature quantum technologies in quantum key distribution (QKD) and quantum random number generators (QRNG) as well as facing some of the most demanding challenges for quantum technologies, such as developing a pan-European quantum communication network, even a global network.
Every day, about one million CPU hours are spent worldwide on calculating properties of materials with the aim of identifying new materials that meet specific requirements. Powerful classical simulation methods are able to predict properties of quantum many-body systems in many relevant regimes.
In quantum-optical metrology and quantum imaging, quantum effects of light, and in particular quantum entanglement, are exploited to improve the sensitivity in phase measurements or the spatial resolution of optical systems. In quantum-optical metrology, interferometers are used to measure the optical phase (and in this way e.g., length differences as in gravitational-wave detectors).
The NV center in diamond behaves like an artificial atom trapped in the diamond crystal with a position controlled at the nanometer scale. Its spin state can be optically polarized and coherently manipulated at room temperature and it can be optically detected. This results in a quantum sensor with extreme sensitivity and nanometer scale spatial resolution.
When you think about Quantum Technologies, you might imagine very small devices, as quantum physics becomes important in the realm of the nano-world. However, a peculiar quantum tool, so called ‘squeezed light’ is used in some of the largest machines on earth: gravitational wave detectors.
