Multi-purpose quantum laboratories from superconducting circuits
Arpit Arora, Emily M. Been, William Munizzi +4
Superconducting circuits (SCs) are the cornerstone of modern quantum technology, enabling scalable computing through coherent control of macroscopic quantum states. Through a legac…
Clifford Orbits from Cayley Graph Quotients
Cynthia Keeler, William Munizzi, Jason Pollack
We describe the structure of the -qubit Clifford group via Cayley graphs, whose vertices represent group elements and edges represent generators. In order to obtain the ac…
Magic and Non-Clifford Gates in Topological Quantum Field Theory
William Munizzi, Howard J. Schnitzer
Non-Clifford gates, used to generate quantum magic, are essential for universal quantum computation. We show that non-Clifford gates arise naturally from path integrals in topologi…
Gravitational back-reaction is magical
ChunJun Cao, Gong Cheng, Alioscia Hamma +3
We study the interplay between magic and entanglement in quantum many-body systems. We show that non-local magic, which is supported by the quantum correlations is lower bounded by…
Topological Preparation of Non-Stabilizer States and Clifford Evolution in Chern-Simons Theory
William Munizzi, Howard J. Schnitzer
We develop a topological framework for preparing families of non-stabilizer states, and computing their entanglement entropies, in Chern-Simons theory. Using the Kac-Mood…
Monogamy of Mutual Information in Graph States
Jesus Fuentes, Cynthia Keeler, William Munizzi +1
The monogamy of mutual information (MMI) is a quantum entropy inequality that enforces the non-positivity of tripartite information. We investigate the failure of MMI in graph stat…
