Quantum Information Processing & Communications
Fet Proactive Initiative in the 6th Framework Programme
Recent technological and experimental progress has allowed an unprecedented capacity of control at the atomic level. This has given rise to an effort to build a quantum computer that would exploit quantum phenomena such as entanglement, up to now not accessible to experiments. Quantum computers hold the promise for solving efficiently some computationally hard problems, like e.g. large integer factorisation or the simulation of quantum systems.
This call follows two earlier calls which led to encouraging results promising scalable quantum computers in the future; quantum algorithms were already successfully implemented on small size (less than 10 qubit) quantum computers. At present, it is still too early to decide which implementation will ultimately be the most successful, (candidates are among others neutral atoms, ions, super-conducting gates, and q-dots) nor are all fundamental problems, like controlling de-coherence and finding promising quantum algorithms, fully understood. The present initiative wants to go one step further towards the practical realisation of a quantum computer.
The objective of this initiative is to contribute to building systems that successfully implement quantum algorithms on small scale systems - including writing, processing and reading of qubits .
The research shall be carried out by teams that integrate as much as possible the theoretical and the experimental aspects. Only approaches that will ultimately be scalable should be considered. Highly important for achieving scalability will be to develop novel experimental schemes to overcome de-coherence, refined quantum-error correction protocols and new protocols for networking of qubits. A possible approach to scalability could also be 'hybrid' systems obtained by interfacing qubit 'memories' (atoms, Q-dots, squids) and carriers of quantum information (photons, phonons, electrons).
Work on developing few qubit applications is highly encouraged, for example in the area of metrology, or simulators of quantum systems.
Theoretical work should aim at further developing quantum information theory. Specific problems to be addressed include physical aspects of quantum information for elucidating concepts such as multi-particle entanglement, work on communication complexity, relation with classical computational complexity theory, etc. In particular work on the development of new quantum algorithms, new schemes for error correction, and protocols for distributed computing, and work in new areas like quantum random walks, etc. is highly encouraged. It should promote a thorough exchange between scientists working in the areas of physics and computer science.
