A Random Matrix Theory of Pauli Tomography
Nathan Keenan, John Goold, Alex Nico-Katz
Quantum state tomography (QST), the process of reconstructing some unknown quantum state from repeated measurements on copies of said state, is a foundationally important…

Anomalous transport in U(1)-symmetric quantum circuits
Alessandro Summer, Alex Nico-Katz, Shane Dooley +1
In this work we investigate discrete-time transport in a generic U(1)-symmetric disordered model tuned across an array of different dynamical regimes. We develop an aggregate quant…

Can Quantum Computers Do Nothing?
Alexander Nico-Katz, Nathan Keenan, John Goold
Quantum computing platforms are subject to contradictory engineering requirements: qubits must be protected from mutual interactions when idling ('doing nothing'), and strongly int…
