Quantum Information Science emerged in the last years of 20th century. Its roots date back to the studies of foundations of quantum mechanics. Since the discovery of quantum algorithms. 1994, which theoretically give exponential improvements in the number of steps, with respect to the best classical counterparts, great progress has been made in quantum software and hardware. The initial emphasis was at developing a proof of principle schemes and devices, that would show than one can engineer and control quantum processes with the aim of performing quantum informational tasks. Now the challenge is scaling-up to large multi-component processors. Such devices necessarily would involve quantum error correction, decoherence free subspaces etc. Quantum computers of sufficient scale to beat classical computers could be achievable in the long-term. However, quantum communication and processing, which is achievable with less complication, is already giving first fruits. Quantum cryptography is an applied technology now, and there are simple solutions in quantum communication complexity and secret sharing, etc. In the workshop we want to discuss generic properties of controllable quantum systems, which enable one to outperform any possible classical devices in many aspects.
Researchers within the European Union have been, and continue to be, at the forefront of quantum information scientific research. They are often working in or cooperating with companies trying to develop marketable quantum devices or spin-off companies based on experience gained in the research. Thus a big part of the current research effort aims at quantum information technology, a strategic aim for quantum information. Some applications may be feasible in the coming three to six years. The aim of large-scale quantum computation sometimes overshadowed medium-term applications of quantum technology. Knowledge of such quantum applications is scattered. The aim of the course in Gdańsk is to give the student a unified view of all these developments, and to prepare him/her to join active research (both in industry as well as in academia).
