News — As part of the , a signature initiative of the Arts & Sciences strategic plan, physicist  and his research group use nano-fabrication techniques to  that allow them to probe fundamental questions in quantum mechanics. Qubits are promising systems for realizing quantum schemes for computation, simulation and data encryption.

Murch and his collaborators published a new paper in  that explores the effects of memory in quantum systems and ultimately offers a novel solution to decoherence, one of the primary problems facing quantum technologies.

“Our work shows that there’s a new way to prevent decoherence from corrupting quantum entanglement,” said Murch, the Charles M. Hohenberg Professor of Physics at Washington University in St. Louis. “We can use dissipation to prevent entanglement from leaving our qubits in the first place.”
