Such stuff as magic is made on: compact operator algebra, stabilizer polytope and the structure of reduced density matrices in a Kitaev spin liquid
Snigdh Sabharwal, Nic Shannon, Paul Skrzypczyk
Quantum many-body systems exhibit rich and complex behaviour. Magic has recently emerged as a powerful new diagnostic for probing such systems, complementing other key features suc…
Reducing measurement error with adaptivity
James Byrne, Noah Linden, Paul Skrzypczyk
We show that adaptivity, also called feed-forward, is a powerful resource in reducing the error of measurement circuits that combine multiple uses of a noisy measuring device. In p…
Resource theory of interactive quantum instruments
Chung-Yun Hsieh, Armin Tavakoli, Huan-Yu Ku +1
Quantum instruments describe both the classical outcome and the updated quantum state in a measurement process. To do this in a non-trivial way, instruments must have the capabilit…
Automated quantum circuit optimization with randomized replacements
Marcin Szyniszewski, Aleks Kissinger, Noah Linden +1
Quantum circuit optimization - the process of transforming a quantum circuit into an equivalent one with reduced time and space requirements - is crucial for maximizing the utility…
Unspeakable Coherence Concentration
Benjamin Stratton, Chung-Yun Hsieh, Paul Skrzypczyk
Unspeakable coherence is a key feature separating quantum and classical physics. Modelled as asymmetry with respect to a continuous transformation generated by a physically relevan…
Characterizing entanglement at finite temperature: how does a "classical" paramagnet become a quantum spin liquid?
Snigdh Sabharwal, Matthias Gohlke, Paul Skrzypczyk +1
Quantum spin liquids (QSL) are phases of matter which are distinguished not by the symmetries they break, but rather by the patterns of entanglement within them. Although these ent…
