Engineered dissipation for quantum information science
نویسندگان
چکیده
Quantum information processing relies on the precise control of non-classical states in presence many uncontrolled environmental degrees freedom. The interactions between relevant freedom and environment are often viewed as detrimental, they dissipate energy decohere quantum states. Nonetheless, when controlled, dissipation is an essential tool for manipulating information: engineering enables measurement, quantum-state preparation stabilization. advances technologies, marked by improvements characteristic coherence times extensible architectures control, have coincided with development such tools that interface classical This Review presents a fundamental aspect measurement devices, highlights role error correction simulation. Controlled can be used to protect information, dynamics enforce constraints. explains basic principles overviews applications correction, sensing

متن کاملOptical Technologies for Quantum Information Science
A number of optical technologies remain to be developed and optimized for various applications in quantum information processing, especially quantum communication. We will give an overview of our approach to some of these, including periodic heralded single-photon sources based on spontaneous parametric down-conversion, ultrabright sources of tunable entangled photons, near unit efficiency sing...
متن کاملQuantum Information Science and Complex Quantum Systems
My subject in this paper is using quantum information science as an approach to the study of complex quantum systems. The work I describe has involved many collaborators at the University of Queensland and MIT, but I would especially like to emphasize the contribution of Tobias Osborne. Let me begin by asking what it is that makes quantum information science a science? Friends outside the field...
