"Protecting Quantum Information" - The interaction of a quantum system with its environment leads to decoherence and is the most important challenge facing the construction of a quantum computer. My research group studies two methods for reducing decoherence: quantum control and quantum error correction. Quantum control is described in terms of physical processes, such as time-dependent Hamiltonians, while quantum error correction is described algorithmically in terms of parity check operators and decoding strategies. In this talk, I will focus on our quantum error correction studies where we have examined how the underlying physics of the system changes the performance of the error correction algorithms. | Faculty Host: Warren S.
