Encoding One Logical Qubit Into Six Physical Qubits (2008)
Shaw, Bilal, Wilde, Mark M., Oreshkov, Ognyan, Kremsky, Isaac, Lidar, Daniel A.
We discuss two methods to encode one qubit into six physical qubits. Each of our two examples corrects an arbitrary single-qubit error. Our first example is a degenerate six-qubit quantum...
Classical Enhancement of Quantum Error-Correcting Codes (2008)
Kremsky, Isaac, Hsieh, Min-Hsiu, Brun, Todd A.
We present a general formalism for quantum error-correcting codes that encode both classical and quantum information (the EACQ formalism). This formalism unifies the entanglement-assisted formalism...
Observation of the radiative decay mode of the free neutron (2006)
Nico, Jeffrey S., Dewey, Maynard S., Gentile, Thomas R., Mumm, H. Pieter, Thompson, Alan K., Fisher, Brian M., ...
The theory of quantum electrodynamics (QED) predicts that beta decay of the neutron into a proton, electron and antineutrino should be accompanied by a continuous spectrum of soft photons. While this...
