TQT-supported graduate student furthers neutron-based quantum material research with visit to Australia
Melissa Henderson, a Ph.D. student at the Institute for Quantum Computing supervised by Dr. Dmitry Pushin, visited the Australian Nuclear Science and Technology Organisation (ANSTO) to perform a small-angle neutron scattering (SANS) tomography experiment and present a seminar. Henderson presented a talk titled “Visualizing Skyrmion Topological Transition Pathways via Three-Dimensional Neutron Tomography” to an audience […]

Implementing High-fidelity Quantum Gates in Multi-level Trapped Ions
Summary The scalability of quantum processors is limited by current error rates for single-qubit gates. By encoding more than a single bit of information within a single ion, multi-level “qudits” offer a promising method of increasing the information density within a quantum processor, and therefore minimizing the number of gates and associated error rates. […]

Quantum State Tomography with Machine Learning
Summary An important challenge in building a quantum computer is quantifying the level of control obtained in the preparation of a quantum state. The state of a quantum device is characterized from experimental measurements, using a procedure known as tomography. Exact tomography requires a vast amount of computer resources, making it prohibitive for quantum […]
