We have developed an efficient quantum control scheme that allows for arbitrary operations on a cavity mode using strongly dispersive qubit-cavity interaction and time-dependent drives .In addition, we have discovered a new class of bosonic quantum error correcting codes, which can correct both cavity loss and dephasing errors [3]. Our control scheme can readily be implemented using circuit QED systems, and extended for quantum error correction to protect information encoded in bosonic codes. Moreover, engineered dissipation can also implement holonomic quantum computation using superconducting circuits.
Liang Jiang obtained his B.S. from Caltech in 2004 and Ph.D. from Harvard in 2009. He was a Sherman Fairchild postdoctoral fellow in the Institute for Quantum Information at Caltech during 2009-2012. Since 2012, he has been Assistant Professor of Applied Physics and Physics at Yale University. Liang’s research interests are AMO physics, condensed matter physics, quantum information science. Liang has made important contributions to secure quantum communication over long distances, including quantum repeater with encoding, optimization of quantum repeaters, and network based quantum computation. Liang has also worked on room-temperature diamond-based quantum information processing, including ultra-long nuclear spin quantum memories, perfect quantum state transfer via thermal spin chains, nano-magnetometer using color defects in diamond. Recently, Liang has been investigating quantum information processing with electro-opto-mechanical systems and superconducting circuits that have ultra-strong couplings and unprecedented non-linearity of microwave photons. Liang has been awarded the Alfred P. Sloan Research Fellowship, and the David and Lucile Packard Foundation Fellowship in 2013.
