Phase transition in magic with random quantum circuits
Pradeep Niroula, Christopher David White, Qingfeng Wang +5
Magic is a property of quantum states that enables universal fault-tolerant quantum computing using simple sets of gate operations. Understanding the mechanisms by which magic is c…
Thermal Multi-scale Entanglement Renormalization Ansatz for Variational Gibbs State Preparation
Troy J. Sewell, Christopher David White, Brian Swingle
Many simulation tasks require that one first prepare a system's Gibbs state. We present a family of quantum circuits for variational preparation of thermal Gibbs states on a quantu…
Mana in Haar-random states
Christopher David White, Justin H. Wilson
Mana is a measure of the amount of non-Clifford resources required to create a state; the mana of a mixed state on qudits bounded by ; $S_2…
Conformal field theories are magical
Christopher David White, ChunJun Cao, Brian Swingle
"Magic" is the degree to which a state cannot be approximated by Clifford gates. We study mana, a measure of magic, in the ground state of the Potts model, and argue…
MBL-mobile: Quantum engine based on many-body localization
Nicole Yunger Halpern, Christopher David White, Sarang Gopalakrishnan +1
Many-body-localized (MBL) systems do not thermalize under their intrinsic dynamics. The athermality of MBL, we propose, can be harnessed for thermodynamic tasks. We illustrate this…
