Quantum computing offers solutions for a set of information networking and other related challenges that would otherwise be impractical to achieve with classical computers.
Several researchers at Bell Labs have served as pioneers in this field including Peter Shor (integer factorization and discrete logarithm / Shor’s Algorithm) and Luv Grover (amplitude amplification / Grover’s Algorithm.)
Today, Alexei Ashikhmin is collaborating with a number of university departments to increase the efficiency of quantum computing (e.g., Quantum Error Correction Codes, Fault-Tolerant Threshold, and Quantum Overhead).
Quantum interferometer for detecting non-Abelian statistics.
Robert Willett and Gerardo Gamez are exploring the use of topological quantum computational qubits as the basis for a more robust quantum computing solution – specifically leveraging non-Abelian properties in semiconductor crystals grown via molecular beam epitaxy. They have been working on the design, fabrication and characterization of devices that harness the quantum coherence in these macroscopic quantum topological states.
"It is wonderful, interesting new physics … these two states, the unwound and the wound, provide the basis for topological quantum computation — that’s the switch, that’s the on-off switch."

In collaboration with researchers at Rice University and the Max Planck Institute, Gavin Scott is using nanoscale structures as tunable model systems for investigating emergent transport phenomena and highly correlated states that arise as a result of strong interactions between charge carriers.
