The concept of multiple-particle interference is discussed, using insights provided by the classical theory of error correcting codes. This leads to a discussion of error correction in a quantum

It is shown that a classical error correcting code C=[n,k,d] which contains its dual, C/sup /spl perp///spl sube/C, and which can be enlarged to C'=[n,k'>k+1,d'], can be converted into a quantum code
Overhead and noise threshold of fault-tolerant quantum error correction
Fault-tolerant quantum error correction (QEC) networks are studied by a combination of numerical and approximate analytical treatments. The probability of failure of the recovery operation is
High-fidelity readout of trapped-ion qubits.
A single-shot qubit readout with a fidelity sufficient for fault-tolerant quantum computation and an optical pumping scheme to transfer a long-lived hyperfine qubit to the optical qubit, capable of a theoretical fidelity of 99.95% are demonstrated.
Active Stabilization, Quantum Computation, and Quantum State Synthesis
Active stabilization of a quantum system is the active suppression of noise (such as decoherence) in the system, without disrupting its unitary evolution. Quantum error correction suggests the

  • 8 August 1996
It is shown that information theory provides valuable concepts for the experimental use of ion traps, especially error correction, and conversely the ion trap provides a valuable link between information theory and physics, with attendant physical insights.
Isotope-selective photoionization for calcium ion trapping
We present studies of resonance-enhanced photoionization for isotope-selective loading of ${\mathrm{Ca}}^{+}$ into a Paul trap. The
Religious Language

Religion is considered as a social phenomenon, having both good forms and bad forms. The widespread modern nervousness around religion is recognized, but that nervousness itself often misconstrues
Radiation force in the magneto-optical trap
An overview of the theory of the magneto-optical trap is presented, along with measurements of the effect of an imbalance in the intensities of the trapping beams. This investigation tests the theory
