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…
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…
Navigating the Quantum Resource Landscape of Entropy Vector Space Using Machine Learning and Optimization
Nothando Khumalo, Aman Mehta, William Munizzi +1
We present a machine learning framework to study the dynamics of entropy vectors and quantum resources, including entanglement and magic, focusing on violations of entropy inequali…
Combining Error Detection and Mitigation: A Hybrid Protocol for Near-Term Quantum Simulation
Dawei Zhong, William Munizzi, Huo Chen +1
Practical implementation of quantum error correction is currently limited by near-term quantum hardware. In contrast, quantum error mitigation has demonstrated strong promise for i…
A Compact Framework for Analyzing Asynchronous Entanglement Distribution in Quantum Networks
Emma Hughes, William Munizzi, Prineha Narang
This work introduces a compact framework for analyzing asynchronous entanglement distribution protocols under realistic error models. We focus on two contemporary protocols: sequen…
Efficient Multiparty Entanglement Distribution in Dynamic Quantum Networks
Roberto Negrin, Nicolas Dirnegger, William Munizzi +2
Distributing multipartite entanglement over a quantum network means routing it through a shared resource state. Existing measurement-based schemes search for a fresh path and re-ve…
Bit by Bit: Gravity Through the Lens of Quantum Information
William Munizzi
This dissertation reviews several recent advances at the intersection of quantum information and holography. In holography, properties of quantum systems admit a gravitational inte…
Bounding Entanglement Entropy with Clifford Double Cosets
Cynthia Keeler, William Munizzi, Jason Pollack
Following on our previous work arXiv:2204.07593 and arXiv:2306.01043 studying the orbits of quantum states under Clifford circuits via `reachability graphs', we introduce `contract…
Entropy Cones and Entanglement Evolution for Dicke States
William Munizzi, Howard J. Schnitzer
The -qubit Dicke states , of Hamming-weight , are a class of entangled states which play an important role in quantum algorithm optimization. We present a gene…
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…
An Entropic Lens on Stabilizer States
Cynthia Keeler, William Munizzi, Jason Pollack
The -qubit stabilizer states are those left invariant by a -element subset of the Pauli group. The Clifford group is the group of unitaries which take stabilizer states to…
