PHY 354/.654 ; An Intro to Quantum Computing will be offered Spring of '24. This class has limited capacity and fills fast, so sign up early.

The Quantum Computing Working Group at Wake Forest University is a community of scientists and engineers from across disciplines, drawn together through an interest in quantum information theory, quantum materials, and quantum sensing. The group sponsors: informal meetings and talks, workshops, as well as some funding for guest scientists that work with our team members. We are also actively involved in Wake's emerging graduate program in Quantum Information Sciences (QIS). Our activities are open to all WFU students, faculty, and staff.

On the left is a five qubit register under development by members of the QCWG. It was fabricated in the WFU cleanrooms at NANOTEQ and its general computation purpose is being tested by groups at WFU and in Germany.

This is just one of several quantum information technology programs ongoing at WFU.

the Quantum teams

Here is what is going on within the group in the quantum information space. Of course this isnt a complete listing, but it is updated regularly.

Ajay Ram Srimath Kandada

We study the chemical and physical factors that govern dynamics in a wide class of materials through advanced optical spectroscopic techniques. Our primary tools are based on sources of ultrafast optical pulses and quantum entangled photons in the visible-NIR spectral regions

Emilie Huffman

The Huffman group devises tests for quantum computing hardware that measure the degree to which the behavior cannot be explained classically, and thus provide metrics for quantum performance. Dr. Huffman designed quantum circuits to demonstrate that the original IBM quantum hardware violated classical mechanical assumptions (macrorealism) through violating Leggett-Garg inequalities. These inequalities can be applied to systems as small as a single qubit. Moreover, rather than requiring spatial separation of qubits the way Bell inequalities do, they instead rely on time separation of measurements and thus are more easily adaptable to a variety of quantum platforms. Huffman currently also works on error-mitigated simulations of quantum systems relevant to condensed matter physics and particle physics using quantum link models, which can be straightforwardly set up with two-level building blocks.

Stephen M. Winter

We do theoretical condensed matter physics in the area of Quantum Materials — including quantum magnets and topological insulators. We use a variety of theoretical approaches – including large numerical simulations and analytical (pen on paper) calculations – to try to model experiments on real materials, as well as classify and predict new quantum phases.

David L. Carroll

We study qubits based on topological systems for use in quantum information processing. We use lithography and direct writing technologies to create qubit registers similar to those using transmons but with our own twist.

Synthesis and characterization studies of higher order topologies in materials systems for testing of the stabilization conjecture - a concept that we believe will lead to room temperature QC.

Topological systems are also being studied as ideal many-body accumulation platforms (MBA) in Floquet systems - ie. topological time crystals.

Vojislav Krstic (FAU - Erlangen DE)

Transport and magneto transport properties of 2D chalcogenide topological systems. The focus is currently on chiral materials.
