Classical Simulability of Quantum Circuits with Shallow Magic Depth
Yifan Zhang, Yuxuan Zhang
Quantum magic is a necessary resource for quantum computers to be not efficiently simulable by classical computers. Previous results have linked the amount of quantum magic, charac…
Eliminating Surface Oxides of Superconducting Circuits with Noble Metal Encapsulation
Ray D. Chang, Nana Shumiya, Russell A. McLellan +15
The lifetime of superconducting qubits is limited by dielectric loss, and a major source of dielectric loss is the native oxide present at the surface of the superconducting metal.…
Characterizing MPS and PEPS Preparable via Measurement and Feedback
Yifan Zhang, Sarang Gopalakrishnan, Georgios Styliaris
Preparing long-range entangled states poses significant challenges for near-term quantum devices. It is known that measurement and feedback (MF) can aid this task by allowing the p…
Nanoscale sensing of spatial correlations in nonequilibrium current noise
Yifan Zhang, Yifan F. Zhang, Rhine Samajdar +1
Nitrogen-vacancy centers are spatially resolved probes of current noise. So far, current noise sensing with NV centers has primarily been used as a way to probe equilibrium transpo…
Nonlocal growth of quantum conditional mutual information under decoherence
Yifan Zhang, Sarang Gopalakrishnan
Local measurements cannot create entanglement, but they can convert short-range entanglement to long-range entanglement, as in quantum teleportation. This phenomenon of measurement…
