Empirical Evaluation of Circuit Approximations on Noisy Quantum Devices
Noisy Intermediate-Scale Quantum (NISQ) devices fail to produce outputs with sufficient fidelity for deep circuits with many gates today. Such devices suffer from read-out, multi-qubit gate and cross-talk noise combined with short decoherence times limiting circuit depth. This work develops a methodology to generate shorter circuits with fewer multi-qubit gates whose unitary transformations approximate the original reference one. It explores the benefit of such generated approximations under NISQ devices.
Enhancing Simulations of Curved Spaces with Qubits
One of the mind-bending ideas that physicists and mathematicians have come up with is that space itself—not just objects in space—can be curved. When space curves (as happens dramatically near a black hole), sizes and directions defy normal intuition. Understanding curved spaces is important to expanding our knowledge of the universe, but it is fiendishly difficult to study curved spaces in a lab setting (even using simulations).
UMD Leads New $25M NSF Quantum Leap Challenge Institute for Robust Quantum Simulation
The University of Maryland has been tapped to lead a multi-institutional effort supported by the National Science Foundation (NSF) that is focused on developing quantum simulation devices that can understand, and thereby exploit, the rich behavior of complex quantum systems.
