Reduction of Decoherence in Quantum Information Systems Using Infinite-Dimensional Direct Adaptive Control
Abstract
Using Quantum Mechanical systems to store and retrieve information and use itquantum computing is a new aspect of physical science. These systems are inherently infinitedimensional systems and their dynamic behavior is not well known. What needs to be controlled,are the quantum gates that do all the computational work but must remain reversible because thegates are expected to be unitary operators in the Hilbert space of quantum system states. Thesegates will suffer some decoherence of this unitatrity because they are open systems and subjectto interaction with other related quantum systems. Consequently, they will not operate as theideal systems they are expected to be and will produce significant errors. Direct adaptive controldoes not use detailed information about the gates, but can still be used to reduce decoherence .This proposal focuses on using our research in adaptive control of infinite dimensional systemsto explore how these feedback control ideas in conjunction with quantum gates and quantumerror correction can reduce decoherence in quantum information and computing.
