Research summary

The continuous tendency and progress in downscaling electronic devices to the deep nano-scale already brought to consideration the emergent of quantum effects. Fundamental quantum phenomena, influenced and tailored by surrounding nano-structuring, with no doubt will be the main challenge and the key feature of the future technological progress. Variety of quantum effects were already proposed and even employed for several industrial applications. Devices that are engineered according to quantum-mechanical concepts will find use in various applications, communications, computations, imaging and biomedicine to name a few.

As one of the examples it is worth noting secure communications and quantum computing. While classical security keys are based on exponential complexity in their decoding (using classical computers, available nowadays), the quantum keys are ideally 100% secure, basing on fundamental physical concepts. Most commonly known quantum key distribution protocols are based on single photons and rely on ‘no cloning’ of states postulate or on entangled states, when a secret key is created only after certain measurements take place. The secure quantum channels are already used in Switzerland to connect between banks and even count votes at elections. Computations relying on quantum phenomena, namely replacing classical bit by q-bits, promise much faster and efficient realizations of different computational tasks, such as integer factorization problem. Another example of outstanding application of cross-disciplinary quantum technology corresponds to the bio imaging and medicine. The resonances of most of the molecules in the human body appear in the mid-infrared (MIR) range, and there is a crucial need to improve the quality and widen the scope of medical diagnostic imaging. Recently, a number of solutions based on Quantum Coherence Tomography were demonstrated for detecting MIR efficiently employing the quantum effect of entanglement.
